Hi Mike:

Thanks for LVZ. Brews ohare (talk) 23:42, 21 February 2010 (UTC)

You're welcome, thanks for the expansion. I need to find out a bit more about the other LVZ, known also as the ULVZ Ultra Low Velocity Zone. I'm working on a Plate reconstruction page, which is nearly ready to go live, I'll value your input when it's ready. Mikenorton (talk) 23:45, 21 February 2010 (UTC)

Need help to save current Articles for deletion at WP:EARTHQUAKES

Hi-I saw your name on the talk page for WPEarthquakes. There was an anonymous IP who nominated four articles for deletion on Feb. 27th. I would really like to save these articles, as it would be a shame to see them go. Could you provide some input at their AfD talk pages, as I'm worried that the "delete" votes may outnumber the "keep" ones. Thanks, --Funandtrvl (talk) 03:04, 6 March 2010 (UTC)

I've voted to keep the Eureka event as clearly notable for its magnitude, but I'm in two minds about the others and have therefore not voted. Mikenorton (talk) 09:01, 6 March 2010 (UTC)

Gardner's relation

Hi. I saw you edited this article and also saw that you have a lot of experience with wikipedia and its methods. I want to ask you a questions. Is it possible to put up this image in the article? [[1]] It's taken from the original paper that is cited under the references. -Hamsterlopithecus (talk) 00:30, 9 March 2010 (UTC)

I'm afraid not. You would need the permission of the copyright holders, which is unlikely in this case. I'll see if there's any data around online from which such a plot could be reconstructed. Cheers, Mikenorton (talk) 07:42, 9 March 2010 (UTC)
Gotcha. Let me know if I can help! Hamsterlopithecus (talk) 01:42, 10 March 2010 (UTC)


Hey there Mike, I tried to come up with a hook [[2]]. Feel free to tweak it or change it completely if you wish. I listed you as the expander and myself as the nominator: that way, you get more credit, as you deserve. Best as always! ceranthor 04:32, 11 March 2010 (UTC)

Oh, and btw, nominate more of those articles at DYK! They make some great hooks: people are really into powerful earthquakes (particularly their effects ;). ceranthor 04:33, 11 March 2010 (UTC)
Thanks, the hook is fine, sometimes it's tough to get one that really grabs people's attention. I've nominated lots of my articles for DYK, but some of these with no 'human interest' are pretty difficult, like the 1965 Rat Islands earthquake, for instance, cracks in a runway and $10,000 damage are a bit underwhelming for one of the strongest ever quakes. Mikenorton (talk) 22:23, 12 March 2010 (UTC)
Agreed, some earthquakes are a lot more fascinating than others! Apart from this, the article looks good. We should try to collaborate on articles more often. ceranthor 22:37, 12 March 2010 (UTC)
Ha, you would almost think that I'd copied the infobox from the 1730 Valparaiso quake, thanks for spotting that. As to earthquake articles, I'm always happy to collaborate. I'm currently building an article for the 1963 Kuril Islands earthquake here, although I can't find a lot of information. Cheers, Mikenorton (talk) 22:43, 12 March 2010 (UTC)

Volcanologist request

Hi Mike,

Ceranthor, Carcharoth, and I brought the article on David A. Johnston, the volcanologist who died in the Mount St. Helens eruption, to FAC. We're hoping that if we get enough reviews to get it through FAC in a reasonable amount of time that it can be the featured article of the day on May 18, the 30th anniversary of the eruption.

If you have the time, could you please look through it and review it? (And if you don't have the time, don't worry.) Thanks!

By the way, I still intend to help on lithology and the others in your sandboxes; this article just took up all of my Wikipedia time, and I'm headed out of town Wednesday. Someday... Awickert (talk) 04:20, 13 April 2010 (UTC)

Hi Andy, I hope to take a look at this later today - I've been a bit tied up at DYK when I've had some spare time, as the backlog of unapproved nominations there was getting rather serious. Cheers, Mikenorton (talk) 11:47, 17 April 2010 (UTC)
Thanks very much - as you may have noticed, I've been pretty tied up recently as well. Wikipedia is a fun project, but work gets in the way! (Yes, your sandboxes are still in the back of my mind.) Awickert (talk) 05:51, 21 April 2010 (UTC)

Re DYK nominations

Hi, just saw your note that you were looking for feedback on your DYK vetting. I'm new to the process myself so take this with a grain of salt but one thing I noticed was that your comment for Sound, Cheshire didn't mention the image. Hooks with an attached image also require you to check that: (a) the image has rollover text (b) the image has alt text (c) the image has no obvious copyright/free use problems Hope that's helpful! - DustFormsWords (talk) 07:35, 13 April 2010 (UTC)

Thanks for that, I had forgotten about the rollover text. I can't find anything that requires alt text, although I know that its very useful. I've checked through the DYK rules but couldn't find anything about this. Maybe I'm just looking in the wrong place. Mikenorton (talk) 22:07, 13 April 2010 (UTC)
Per Manual of Style - Images, best practice is for all images to have suitable alt text. The main page should as far as possible always conform to the Manual of Style and best practice. Hope that helps! - DustFormsWords (talk) 00:12, 14 April 2010 (UTC)

Consulting (Geology)

Iceland: Lava from the Katla and the Hekla volcanic systems result in transitional alkalic basalts and the central volcanos ones result in tholeiitic basalts. Question: Is transitional alkalic basalts the same as high alumina basalt? Thx for an answer :) --Chris.urs-o (talk) 09:43, 17 April 2010 (UTC)

Don't you just love scientific terminology. I had a look at this when the question was raised elsewhere (I can't remember either where that was or whether I got round to replying (apparently the answers are by you at Talk:Basalt and no)). From what I gathered, they were considered by some to be the same but not by everyone, which isn't very helpful. Transitional I take to mean transitional between tholeiitic and alkaline. High alumina basalt was a term introduced by Kuno,[3] who interpreted them to be primary melts of mantle material at depths intermediate between those at which tholeiite and alk-basalt magmas were formed. Others have reckoned that they are more likely to be a result of differentiation of a primary magma at depth. Brody & Marsh reckon that they are primary melts, but of quartz-eclogite from the subducting slab - they also point out that it has been shown experimentally that the High-Al basalts can never have been in equilibrium with either an olivine-bearing magma or source rock. I think that this was where I gave up last time :-). This more recent note by Draper [4], does at least define High-Al basalts as aluminium rich tholeiites (which others would probably call transitional I'm guessing). I just found another ref that suggests that some HAB magmas originate by partial melting at the base of continental crust above a mantle upwelling in a rift setting (I have full text access for this one, unfortunately the abstract doesn't go into any detail). I'm not sure if any of this helps. Cheers, Mikenorton (talk) 11:43, 17 April 2010 (UTC)

Thx :) No easy way out so --Chris.urs-o (talk) 11:50, 17 April 2010 (UTC)

Wikipedia:Australian Wikipedians' notice board#WA Earth Quake

Hello again! I was wondering if you could help us out and answer some questions about the 2010 Kalgoorlie-Boulder earthquake. We're wondering about the differences in measuring earthquakes by the Richter and/or the moment magnitude scales. Is the Richter scale used in Australia because that's the quickest measurement from the seismograph? Why does the USGS use the MW scale instead? Do they have different instruments? Thanks, --Funandtrvl (talk) 04:30, 23 April 2010 (UTC)

Not wanting to put Australian earthquakes down, but the Mw scale is used for larger earthquakes M>7 or thereabouts, whereas the local magnitude scale (or Richter) is fine for M<7 earthquakes - it just becomes a poor measure of released energy for biggere events. Hope that helps. Mikenorton (talk) 06:40, 23 April 2010 (UTC)


for this. I was planning on going back to expand it, but looks like you beat me to it. ;) ceranthor 21:13, 10 May 2010 (UTC)

New sources of amber (incl. blue)

Hello Mikenorton.

Did you delete my addition to the Amber page on New sources of amber (incl. blue)? If so, why?

Irwan Holmes (talk) 09:53, 22 May 2010 (UTC)

The edit summary I gave was rv - you'll need a source for this and I've not been able to find any on a quick search - see talk and on the talk page I started a new section to explain why and said I reverted the addition of a new section on blue amber from Indonesia as it was unsupported by sources and I have been unable to find any - it read a bit like an advert. So that's why. If you have a good source for this Indonesian blue amber, then you can add it back. Mikenorton (talk) 10:06, 22 May 2010 (UTC)
Amber (including blue amber) was just discovered in Sumatra a few months ago, so no one has written about it yet—but we can supply photos. Irwan Holmes (talk) 11:30, 30 May 2010 (UTC)

Technical hooks

Technical words are allowed in articles and it's preferable for them to be linked. There is no rule that technical words aren't allowed: Wikipedia:Did you know#The hook. Joe Chill (talk) 20:55, 22 May 2010 (UTC)

Thanks for that, the summary I added was perhaps aimed more at Yoninah in mild exasperation, I have had more technical hooks than this accepted at DYK before, the whole purpose of the project should be to get people to delve deeper into subjects that they haven't encountered before. Mikenorton (talk) 21:01, 22 May 2010 (UTC)
Hopefully he doesn't say anything about my hook: "...that that fungus Epidermophyton floccosum can cause the diseases tinea pedis, tinea cruris, tinea corporis, and onychomycosis?". I hate it when editors that don't understand DYK at all try to check hooks. Joe Chill (talk) 21:05, 22 May 2010 (UTC)
But there are never enough people out there checking hooks (I did one long stint at it when the backlog was huge last month, but I didn't find it the most enjoyable activity), so we have to accept those that are prepared to put in the time and hope that the experienced DYK editors catch any problems that result. Mikenorton (talk) 21:11, 22 May 2010 (UTC)

I changed my wording. I though that it would be obvious what hook I was verifying, but now I think that isn't so. Joe Chill (talk) 23:10, 22 May 2010 (UTC)

Hello. Your account has been granted the "reviewer" userright, allowing you to review other users' edits on certain flagged pages. Pending changes, also known as flagged protection, will be commencing a two-month trial at approximately 23:00, 2010 June 15 (UTC).

Reviewers can review edits made by users who are not autoconfirmed to articles placed under flagged protection. Flagged protection is applied to only a small number of articles, similarly to how semi-protection is applied but in a more controlled way for the trial.

When reviewing, edits should be accepted if they are not obvious vandalism or BLP violations, and not clearly problematic in light of the reason given for protection (see Wikipedia:Reviewing process). More detailed documentation and guidelines can be found here.

If you do not want this userright, you may ask any administrator to remove it for you at any time. –xenotalk 20:44, 15 June 2010 (UTC)


Hi Mike,

I was looking over your first sandbox, and I have two thoughts/questions before I'd feel OK proceeding.

  1. To me, "lithology" is both a long-winded definition (e.g., calcite-cemented sandstone with 93% quartz, 2% feldspar, 5% lithics, well-rounded, well sorted with a grain size distribution of [insert full distribution here, either fine/coarse/very coarse/etc. or actual diameters], and onandonandon..., AND a simple description (e.g., vesicular basalt). Is this the same on the other side of the Atlantic?
  1. Do you think that it would be better to organize the article into "sedimentary", "igneous", and "metamorphic" sections, into which many of the current sections will become subsections? Or do you like the way it is (with classification schemes for different rock types naturally falling into those)?

Awickert (talk) 03:44, 16 June 2010 (UTC)

HI Andy,
You're right that the lede needs to mention both definitions - many of the sources that I found described the term in that way, which is how I use the term as well, so no transatlantic differences in this case I think.
The current layout is just the way that I first thought about it. Dividing it up into the main groups of rocks might mean less tortuous text e.g. in fabric. Would it be too much work to produce two versions? - actually given the rate that we're moving ahead on this I'm not sure that that's a very good idea. I can see advantages to both ways of organising it. I'll prevaricate think about it some more. Mikenorton (talk) 20:46, 17 June 2010 (UTC)
Yes - let's get done with this before we set our sights higher. You're working with me here...
Let me know when you finish contemplating. My family will be in town next week, and I'll be going into the field on the 5th of July, so the week after next (including the preceding weekend) would be my window of opportunity. Awickert (talk) 04:16, 18 June 2010 (UTC)

-- Cirt (talk) 12:03, 17 June 2010 (UTC)

Vangjel Meksi

Hi, thanks for your note on my talk page for the DYK. I actually don't think I can expand that much the article, I think I exhausted all the sources and I don't want to be wordy, unless I bring some citations of the letters of Pinkerton. Do citations count? --Sulmues Let's talk 23:28, 20 June 2010 (UTC)

I'm afraid that they don't. Sorry to disappoint you, it's worth getting hold of DYKcheck or similar if you plan to do more expansions. Mikenorton (talk) 23:31, 20 June 2010 (UTC)

Your note

Hi Mikenorton, what I try to do is make sure the ones which have serious issues don't get through by mistake. I do mark borderline cases with '?', but just the other day I marked one with problems as a '?', and Rlevse still picked it by mistake, which he later had to reverse. He then told me it's better to fail such cases, because of the possible errors in picking them by mistake. I guess the orange color stands out more, so people are less likely to pick it by accident. I assume that any nominator with any interest will be following closely the review comments, and that 'failed' items can still be resurrected with some effort, before they are removed. Crum375 (talk) 23:36, 20 June 2010 (UTC)

Hi Mike, I only now noticed your reply. I agree that people have to be notified, and I do it fairly regularly, although not always immediately. In this case, I felt the orange icon with the simple message "Fails WP:DYKCHECK 5x expansion" would attract the attention of the nominator fairly quickly. I also felt that given that message, the nominator would immediately run WP:DYKCHECK on it to verify (and take the one minute to add it to his Monoboook.js if he doesn't already have it), if he cares about his nomination. As far as the 4.7x as an allowable mark, I would have appreciated knowing about it when I recently spent a lot of extra time and effort expanding my own DYK article to 5x. This is why we have written rules, and being a wiki they are easy to modify at any time, and if there is a special rule that "if your article is over X kB long, you only need to expand it by 4.7x", it should be added to the rule set. If it's not there, I would assume there is no consensus for it, and therefore the 5x remains, even for larger articles. The point is that we can't fool around with rules, because people would get demoralized if they think we have one rule for them, and another for our buddies. Sometimes being "harsh" in the short term, works out as the kindest and most productive approach in the long run. Crum375 (talk) 22:18, 21 June 2010 (UTC)

Looks like we were editing Torridonian at the same time, hope I didn't cause a conflict - I wasn't even aware of it. Might want to explain Sphaeromorphic -- I'm not into paleontology and don't know what it is :) Vsmith (talk) 18:30, 25 June 2010 (UTC)

Unfortunately, it's what the source uses. I think it just means somewhat spherical in shape - it's probably from the original 1907 reference. I think I'll replace it with acritarch, which just means an organic structure that can't be classified, which is obviously true in this case. Thanks for adding all those links - I should have done it before I copied the expansion over from my sandbox, but I kind of get to the stage where I just want rid of the thing. Cheers, Mikenorton (talk) 18:38, 25 June 2010 (UTC)
Acritarch... looks like that one is on my watchlist - edited it way back when, then forgot. Ok, makes more sense now. As to "...all those links...", when reading something new (to me) it's kinda compulsive. Thanks for writing "new stuff"! Vsmith (talk) 03:10, 26 June 2010 (UTC)

Earthquake Map Suggestion

It might be better to find a way to merge the two pictures. The earthquake is near the border but WAS centered in Quebec, so reading about how it affected Toronto, Ontario and seeing no Ontario on the map...

Just a penny for thought. =) CycloneGU (talk) 05:19, 26 June 2010 (UTC)

The infobox uses a location map template which uses the coordinates provided to place the marker in the right place on the location map. The number of location maps is limited, so in this case it's either the whole of Canada or Quebec. If someone created a location map for Central Canada, that would be ideal, but I have no idea how you would go about either doing that or finding someone to do it for you. The alternative is to make a custom map of the area, the location maps are just a really quick solution and in many cases good enough. Mikenorton (talk) 10:20, 26 June 2010 (UTC)

Help out with reviewing DYK nominations!

Hi Mikenorton, the nomination entry system for DYK is backlogged - nominations up till as early as July 4 have yet to receive a single review. There have only been reviews on some articles sporadically, across the board (July 3 to July 10). You may want to consider volunteering your services as a reviewer at this time. We need to clear the "older nominations" before it turns old (and stale). Quick link here. Thanks! AngChenrui (talk) 09:38, 11 July 2010 (UTC)

Actually this is nothing like as backlogged as it was a few months ago, when there often less than 20 approved hooks at any one time. That was the point when I did quite a bit of reviewing. At the moment I concentrate on checking image rollover and alt texts, but if I get some time, I'll see what I can do. Mikenorton (talk) 10:53, 11 July 2010 (UTC)

To create the valley, it's probably transtensional, but I've found no sources that mention that, so I've just added the strike-slip bit and the ref to the article. It would be good to have a geology section, but I fear that there wouldn't be much to go in it. Cheers, Mikenorton (talk) 20:51, 16 July 2010 (UTC)
Thanks, very much, I can just barely pretend that I understand the lingo (I only have a BA in Bio &Phil) but I very much appreciate the contribution.

I was curious if you might be able to generate and upload an image of the valley from the Nasa WorldWind program? I am trying to install it on my MAC but have not yet done so and have never before uploaded an image to wikimedia. If you have the time and the capability and would be willing it would be nice to have an image of the valley itself or an image focused on the valley which includes the local features, lakes alakol and ebinur and some of the steppe, dzungarian plian, and the alatau range. The article goes on DYK tomorrow morning.μηδείς (talk) 21:04, 16 July 2010 (UTC)

DYK for 1949 Khait earthquake

RlevseTalk 06:03, 21 July 2010 (UTC)

Even without being able to check the references (One seems to be on paper, the other is behind a paywall), there must be a unit error somewhere. The DYK and the article itself both talk about volumes measured in Mm3 - as far as I can tell, this is impossible. Note that Mm3 does not mean millions of m3, it means (Mm)3.

The area covered by the Yasman valley slide is about 24.4 km2, with a total estimated volume of 245 Mm3.

If you put that volume on top of that area, it would have an average thickness of about 10 000 000 000 km, or 25 000 times the circumference of the earth! Even with Mm replaced by km, it would still be about 10 km thick. --Ørjan (talk) 09:09, 21 July 2010 (UTC)

The unit 1Mm3 is 1 million cubic metres and is the unit normally used to describe landslide volumes, unless they are more than 1000 Mm3, in which case researchers use km3. That may be confusing (although I never met a Megametre in real life), but it is the unit that is used. The Evans et al. Engineering Geology ref. link should show you the abstract for free and contains the volume information with the units used exactly as they appear in the article and the DYK hook. Mikenorton (talk) 09:30, 21 July 2010 (UTC)
I've added an explanation of the non-standard unit in the article text to prevent any possible confusion. Mikenorton (talk) 09:37, 21 July 2010 (UTC)
Huh. After writing the above, I had a bad hunch about this, so I checked SI prefix which clearly says this usage is not allowed. Maybe that article should be updated to reflect de facto usage. --Ørjan (talk) 09:49, 21 July 2010 (UTC)
Scientists are just looking for units that offer a nice range for what they are describing, most landslides fit neatly in the 10 to 500 million cubic metres range, using 0.01 to 0.5 km3 for some reason doesn't look so good. The M still means million, which is OK in SI but it should probably be rendered as M(m3) (or of course the correct hm3), if a note is needed it should go on the cubic metre page. Hectometres just don't get used very often (at least in the literature I'm familiar with), I would have to think even harder about what a hm3 was. Mikenorton (talk) 10:03, 21 July 2010 (UTC)

Hi, I've got two problems. 1. A lot of articles started by me were nominated for deletion. I do not hope that everyone's gonna think every article worths to be here. If you think there's some article which should be kept, please just keep watching it. 2. I was sent a notification about the deletion nomination for EVERY ARTICLE BY THE SAME GUY and it's annoying.

I try to keep an eye on the AfD lists and contribute when I find an earthquake article up for deletion.

And I certainly wouldn't have had a clear enough head to tell you that I just took a short course on how to use Gale, and if/when I learn it better, I'll try to set up a model run to make figs / animations for WP. And/or I'll just ask for permission to use one of their examples. You can create some pretty nice critical tapers and rifts; if you want to play around, they have prebuilt binaries you can download, sample input files, and a tutorial in their manual. Awickert (talk) 06:28, 11 November 2010 (UTC)
That sounds like fun! I would have killed for that sort of software when I was doing my PhD, attempting to model the propagation of shear zones, perhaps I should have a look at it myself. Mikenorton (talk) 13:23, 11 November 2010 (UTC)
It is fun! I don't even do tectonics and I'm enjoying it. Technology has progressed!
What it does is solve the heat equation coupled with Stokes flow. Faults, etc. are formed in the Stokes flow model via strain weakining and a Mohr-Coulomb-esque criterion. The downside is that the input is written in xml, which makes it sort of a pain to write. It's based on an Australian (Monash U.) code called "underworld", if that means anything to you.
If you have some time, you should download it and go through their "cookbooks" (chapter 5 of the manual). It goes through how to set boundary conditions, etc: maybe you could even try to propagate a shear zone. Awickert (talk) 17:35, 11 November 2010 (UTC)
Never heard of 'underworld' but then I've been a consultant for more than 21 years, so I'm way out of date. I should try to give it a go, maybe even finally write up some of my PhD (like that's going to happen), thanks for mentioning it. Cheers, Mikenorton (talk) 00:04, 12 November 2010 (UTC)

When u make ur maps based on many maps, how do u avoid copyright problems? What one has to avoid doing? Any advices? --Chris.urs-o (talk) 13:50, 11 November 2010 (UTC)

I start with a basic map , e.g. for the Moine Supergroup, File:MainlandMoineOutcrop.png I started with figure 4.3 of the Geology of Scotland, following most, but not all of the boundaries, simplifying a bit here and there, using different symbols and colours instead of patterns, before combining it with figure 4.12 of the same book. This is no different to how I would proceed if I was writing a scientific paper, with the normal formulation being 'modified after author, date or 'based on author, date. As far as I know that's OK, but of course I'm not completely certain. A direct copy needs the permission of the copyright holder, naturally, and the question of how much you have to change the original to stay clear of copyright concerns is not entirely clear. If you compare the originals you'll note that I've left off the inset maps of Orkney and Shetland, I've left off the Loch Quoich Line (LQL) and all the location labels, simplified the Moine Thrust by missing out later faults, distinguished 'older' from 'newer' granites based on another map in addition to producing a single map rather than two. Slavish copying is what you need to avoid, but precisely how much change from the original is 'enough'? - good question. Mikenorton (talk) 14:22, 11 November 2010 (UTC)
For the File:Hebridean Terrane.png map I wanted to show detail in the Lewisian and the breakdown of the post-Lewisian cover, which meant taking boundaries from three of the maps in the book, I also needed to use another one of Graham Park's papers to check up on (and modify) some of the boundaries in the Geology of Scotland, so my map differs from all the other three, because, as I was using colours, I could distinguish more rock units than on the original. I'm almost certain that no-one would claim that as a copyright infringement. Mikenorton (talk) 14:31, 11 November 2010 (UTC)
Thx, which software do u use? --Chris.urs-o (talk) 14:50, 11 November 2010 (UTC)
Inkscape, which I like using and has good functionality (that and the fact that it's free of course), although I have so far been unable to export .svg files, something that I've so far failed to get to the bottom of. I just upload .png files, which is good enough. Mikenorton (talk) 14:55, 11 November 2010 (UTC)

Hi Mike! I'm trying to finish the Ambato article and ship it off to FAC. I just realized that a few of the sources in the final section are ones that I'm unfamiliar with; it appears you added them. Thanks, first of all, and second, are they reliable? One of them isn't fully sourced; if you could finish the reference or supply the url for it I'd appreciate that! Thanks. ceranthor 00:00, 14 November 2010 (UTC)

Hi Ceranthor, yes those were down to me after the GA reviewer suggested that an 'aftermath' section would help. The source with no url (#18) was borrowed from the Ambato article, I've replaced it with a better one, although it is in Spanish. Ref no. 20 should be fine as is, the cathedral one (#19) is not ideal, as it comes from a travel company and I'm doing my best to find an alternative - if all else fails, that sentence will need a rewrite to match a better quality, if possibly less informative, source (I mean, building a huge white cathedral is a very clear statement of something). Ref #17 could be better, maybe the new spanish one will be sufficient on its own. Mikenorton (talk) 11:08, 14 November 2010 (UTC)
I've added a new source about the cathedral, in spanish again, which I think says that it "stands out, due to its great size, in the context of the architecture of its urban surroundings", which fits the existing text pretty well. Mikenorton (talk) 14:11, 14 November 2010 (UTC)
Hmm, all that's left is the blog. ceranthor 15:18, 14 November 2010 (UTC)
