Meaning change by Typo?[edit]

"A massive debris avalanche triggered by an earthquake measuring 5.1 on the Richter scale caused an eruption that reduced the elevation of the mountain's summit from..."

Is the word 'by' missing from that statement? (to wit..

"A massive debris avalanche triggered by an earthquake measuring 5.1 on the Richter scale caused *BY* an eruption that reduced the elevation of the mountain's summit from ..."

I'm suspicious of the idea that the debris avalanche, or the earthquake, caused the eruption - rather the other way around..

The sequence is very well understood. The earthquake happened first causing the bulge to slump, the "massive avalanch", downslope. That released the explosive pressure.98.164.84.48 (talk) 20:22, 19 May 2018 (UTC)

360° panorama is a beautiful photo, but it's not a 360° panorama[edit]

Near the bottom of the article is a beautiful photo of the crater up close, whose caption begins with the description:

"360° panorama from the summit of Mount St. Helens as seen in October 2009".

But this photo cannot possibly be a 360° panorama, simply because its left side does not anywhere match up with its right side.

I suggest that whoever introduced the photo relabel it — but this time, correctly. (Such as: "Wide-angle panorama . . .".)Daqu (talk) 21:24, 8 July 2013 (UTC)

P.S. This is the very same photo that appears directly above this section on this talk page, as the photo that apparently was the picture of the day on April 10, 2013, taken by Gregg M. Erickson.

See the discussion on this very point several sections above at Talk:Mount St. Helens#Edit request. Mikenorton (talk) 22:20, 8 July 2013 (UTC)
As mentioned in the earlier discussion, the two sides do in fact match-up (the clouds shifted slightly during the exposure, but the landmarks all tie-out when you adjust for the camera apparently not having been held level - ie: the left side of the image is is pointed marginally lower than the far right side). This can be easilly seen by downloading the image, then pasting two copies of it side-by-side in whatever program you have available - even office products like Excel work for this. When doing this, the image appears to be just under 360° (there's a thin sliver missing, so maybe closer to a 359.5° image. Close enough.) --- Barek (talkcontribs) - 22:58, 8 July 2013 (UTC)
The panorama can be viewed with [1]. Barek is right -- it's 360, with a little vertical mismatch. —hike395 (talk) 10:36, 9 July 2013 (UTC)
To check this, I downloaded the image, sliced it in half vertically, and ran it through Photoshop to see if the edges would match; they do, albeit with a slight shift, but that is down to the photographer and environment, not a lack of angular coverage.  drewmunn  talk  11:07, 9 July 2013 (UTC)
  • I know this is old, but I've just realised why the issue was brought up. Having seen it now on my iPad, the container in which it is stored cuts it down on smaller screens.  drewmunn  talk  14:39, 25 October 2013 (UTC)

NRHP listing[edit]

Mount St. Helens was listed on the National Register of Historic Places on September 11, 2013, under its Native American (Cowlitz) name, Lawetlat'la, as a Traditional Cultural Property. This has not yet been mentioned in the article. I don't have time to add it myself, especially since the addition needs to be done well so as not to degrade the quality of an article that has reached FA status. Here is a link to a feature page about it on the National Park Service's website, which also includes a link to the full NRHP nomination documentation. SJ Morg (talk) 11:26, 27 October 2013 (UTC)

I have added a bit more information about this from the nomination. There is definitely more that could be written about the significance of the mountain to the local indigenous cultures, and it probably also deserves a sentence or two in the lead. Magic♪piano 17:14, 30 October 2013 (UTC)

Revegetation of Mount St. Helens following the 1980 eruption[edit]

I was a bit surprised to find no encyclopedic summary of the revegetation process following the massive eruption 34 years ago.

Am I looking in the right place? Is there some other article in Wikipedia that covers this topic, based on all the research papers that have been written about plant and wildlife regrowth and repopulation of the damaged area and new topographical features?

I searched the Talk page and archives for "revegetation", "vegetation", "regrowth", etc. No luck. Surprising. N2e (talk) 01:11, 14 September 2014 (UTC)

Photo- Mt St Helens as seen from Portland OR[edit]

The one which describes it as Mt Fuji of the US. That's news to me. Someone has good eyes. Could it be Mt Hood?161.97.140.117 (talk) 16:21, 30 October 2015 (UTC)

The source of this picture (an engraving not a photo) looks reliable enough [2] and the viewpoint seems OK when checked on Google Earth - the description says " Detail of engraving of Portland, Oregon and Mount Rainier and Mount St. Helens, Washington. (Click to enlarge). The Columbia River is middleground and the Willamette River is in the foreground. Created by E.S. Glover. Published 1879, San Francisco. "Bird's-eye-view", looking east to the Cascade Mountains. Original lithograph shows Mount Rainier, Mount St. Helens, Mount Adams, and Mount Hood, and also the Columbia River and the Willamette River". Mikenorton (talk) 16:53, 30 October 2015 (UTC)

Using peakfinder ( www.peakfinder.org ) both Mt Hood and Mt St Helens are visible from Portland Oregon, and if the view point is adjusted to the line of hills to the SW, eg https://www.peakfinder.org/?lat=45.4977&lng=-122.6822&azi=75&zoom=5&ele=122 the view fits quite well, and the small peak to the left in the lithograph matches the shape of Goat Mountain in PFinder, with nothing of similar shape near Mt Hood.

Semi-protected edit request on 24 May 2016 alter: catastrophic[edit]

2nd para reads: "Mount St. Helens is most notorious for its catastrophic eruption on May 18, 1980, at 8:32 a.m. PDT" however "catastrophic" is actually a technical term referring to the magnitude of the eruption under the volcanic explosivity index (VEI) and not just descriptive. 1980 St Helens was a VEI 5 eruption and so is paroxysmic. 131.217.40.224 (talk) 04:55, 24 May 2016 (UTC)

Check sources (outside of WP) and it seems to be right. Thanks — Andy W. (talk ·ctb) 00:21, 26 May 2016 (UTC)
