Talk:Mount St. Helens

Red Zone and Blue Zone

Adding to my previous entry, the Red Zone and Blue Zone also played a major role in keeping the death toll to a minimum. The Red Zone and Blue Zones were roughly ten-and-20 mile boundaries around the volcano (with exception to the northwest side, in wich the Red and Blue Zone bordered only three miles away from the summit, and both restricted zones weren't full complete "circles" as some thought), and were signed into order on April 30 by Dixy Lee Ray. The Red Zone was a restricted area closed to all persons except those in the scientific community, while the Blue Zone was a limited-access restricted area, which allowed approved persons in only on a day-to-day basis, and only during daylight hours.

Interestingly, of the 57 killed, only three were in the Red Zone. The remainder were both either within, or totally outside the Blue Zone entirely.Srosenow 98 (talk) 10:02, 18 January 2008 (UTC)

The "Source" note was part of Srosenow's preceding post, yes? (Otherwise, since the signature precedes it, it almost looks as though the note was added by the author of the following paragraph.) Memetics (talk) 07:20, 20 August 2009 (UTC)

The american goverment set a 25 mile radious and anyone who lived in that radious were evacuated from there homes to be protected from the eruption but one person who refused to leave was Harry Trumen who was 84 years old and had lived in his house for 50 years and that is why he would not leave —Preceding unsigned comment added by 86.163.147.223 (talk • contribs) 11:04, 3 November 2008 (UTC)

Carbon contribution?

I came looking for info on how much carbon Helens has been releasing with it's new activity. I ended up googling since nothing was here, one newspaper reported between 500-1000 tons a day (as compared to a typical US family contributing 50 tons a year). That's the amount of 5,000 families... Is there some hard reference that could be added? -RJFerret 03:01, 17 July 2006 (UTC)

No -- 12.116.162.162 21:05, 23 August 2007 (UTC)

Could you provide a link to the article you alluded to? I think it may have been referring to tons of total material, not carbon / greenhouse gases, being ejected during that eruption. (During a lecture in fall 2006, I recall the geology instructor at Lower Columbia College in Longview saying that the eruption was releasing about a cubic meter of material every second. Anyone care to convert that figure to British tons per day?) Memetics (talk) 06:58, 20 August 2009 (UTC)

{{geodata-check}}

Please note that the coordinates in this article need fixing as:

THE COORDINATE IS 48 DEGREES WHICH I SEEN IN ANOTHER WEBSITE

The other website appears to be incorrect.[1] Walter Siegmund (talk) 22:53, 14 January 2009 (UTC)

{editsemiprotected}} Error in image caption

Incorrect: Mount St. Helens the day before the 1980 eruption, which removed much of the northern face of the mountain, leaving a large crater (caldera).

It is not a caldera, just a volcanic crater. A caldera is a collapsed volcano. —Preceding unsigned comment added by Ddrmaxgt37 (talk • contribs) 18:45, 17 February 2009 (UTC)

"Johnston uttered his famous last words" seems ambiguous. Would seem more accurate to say "Johnston radioed his famous last words", based on the content of the article cited for the info. Memetics (talk) 05:22, 20 August 2009 (UTC)

Edit request

{{editsemiprotected}} In the "360-degree panorama," the picture is actually only a "180-degree panorama' as the entire mountain is visible as the photographer positioned along the southern rim. If this were a 360-degree panorama, half the photo would be filled with the rolling hills to the South and you'd see Oregon to the South, etc.

Mortonjhop (talk) 18:51, 27 March 2010 (UTC)

As far as I can tell, this is a true 360 degree image. The right hand end of the picture matches up with the left hand end (pretty much perfectly). Note that the lakes referred to at the right hand end of the image, lie south of the mountain. Mikenorton (talk) 19:16, 27 March 2010 (UTC)

It seems 360 to me too. But, if consensus shows otherwise, someone else can do the edit for you or you can request an edit again. --JokerXtreme (talk) 19:38, 27 March 2010 (UTC)

It appears to be a full (or very close to a full) 360 to me as well - at the very least it's clearly much more than the 180 claimed in the edit request. Any aparent inconsistency on each end can easilly be attributed to artifacts from the stitching of multiple images.

To get some clarification, I've requested that Farwestern (talk · contribs) - who uploaded the image - to provide feedback/clarification on the image. --- Barek (talk • contribs) - 19:55, 28 March 2010 (UTC)

also, can some one enter what was learned after the eruption?

The details of the photo says it is 360°, the photo poster says s/he often shoots 360° photos, and it has survived commons Featured Photo review with that description—no small feat. Besides it looks 360° to me too (Mount Hood at 80% from left edge; Mount Jefferson, 88% (with the Three Sisters just to its left); Mount Rainier, 50%; Mount Olympus, 25%; possibly Saddle Mountain, 15%; and all the lakes around the south side. The split appears to be approximately WSW. —EncMstr (talk) 20:28, 28 March 2010 (UTC)

Yes, it really is a true 360. To help clarify this point I have created a map on google that identifies various notable landmarks in the image. http://maps.google.com/maps/ms?hl=en&client=firefox-a&ie=UTF8&msa=0&msid=116803011662351216901.000482fdf07a6e4870a4d&ll=46.191358,-122.184277&spn=0.027034,0.075102&t=p&z=14 I hope this helps --Farwestern (talk) 06:41, 30 March 2010 (UTC)

"I hope this helps". May help to point out how close to the crater you were standing when you took the picture. I am guessing the crater would normally fill a person's vision from where you were standing, when looking at its center. It looks "normal" in the photo, which may be what is throwing off people's perception. —Preceding unsigned comment added by 72.102.189.120 (talk) 02:27, 28 July 2010 (UTC)

Who walked out with a video camera?

There was a man on the south side of the mountain when it erupted, who managed to find his way to safety through nearly complete darkness from the ash blocking the sun. He had a portable video camera (which 30 years ago was barely carryable by one person) and recorded his ordeal. I remember seeing part of it on TV once.

Dave Crockett -- see [2] and [3]. — Myasuda (talk) 02:14, 23 April 2010 (UTC)

There's a very short bit on him in When Yellowstone Erupts but no mention of his name or any other details. Bizzybody (talk) 07:13, 1 September 2010 (UTC)

The two links I included above have plenty of information on Crockett (then age 28, a photographer for KOMO-TV in Seattle). — Myasuda (talk) 14:33, 1 September 2010 (UTC)

Bigfoot stuff

I've removed the addition of "bigfoot" to the "Exploration by Europeans" as it was not supported by the references given and was rather out of place. Vsmith (talk) 13:40, 18 July 2010 (UTC)

Ecological recovery.

Have been up to St. Helens several times in the past few months and am amazed by the devastation some of the land still exhibits after 30 years. The only "recovery" of note that I can see are where trees were planted by the lumber companies around the edges of the park. Anyone interested in adding a section talking about this? Cannot provide the scientific expertise to discuss this, but can take photos. The one of Johnston Ridge does not convey the moonscape still present in parts of the park. 72.102.189.120 (talk) 02:35, 28 July 2010 (UTC)Bill

Different earthquakes cause 1980explosion/eruption?

Thanks for spotting that, I've changed the 5.0 to 5.1 in the lede, because that matches the sources. Mikenorton (talk) 07:13, 25 March 2011 (UTC)

Mushroom cloud picture

The May 18 mushroom cloud as seen from Toledo, Washington, 35 miles west of the mountain.

I think this picture would be a useful addition to the article. It shows the full profile of the initial mushroom cloud. Within a couple of months I may be able to upload a high resolution version made from a dozen different negatives stitched seamlessly together. This crude version is all I have for now. (Another composite from these same negatives was printed in a National Geographic book in the 1980s.) The photographer has agreed to make the negatives available for reprocessing with modern digital technology. It should make a spectatular image; in the meantime this low-resolution image is uniquely informative. HowardMorland (talk) 02:59, 3 May 2011 (UTC)

I think the overall appearance of this article is becoming degraded by too many images. Granted many if not most are important to the text but things are getting crowded.

Edit request from Durahan26, 10 August 2011

Under "Modern eruptive period" you have the following sentence. "The removal of the north side of the mountain reduced St. Helens' height by about 1,300 feet (400 m) and left a crater one to 2 miles (3.2 km) wide and 0.5 miles (800 m) deep, with its north end open in a huge breach. The eruption killed 57 people, nearly 7,000 big game animals (deer, elk, and bear), and an estimated 12 million fish from a hatchery.[7]" Please change the "and left a crater one to 2 miles (3.2 km) wide" to "and left a crater 1 to 2 miles (3.2 km) wide". Might as well keep things consistent and use the number "1" instead of the letters "one." Thanks. Durahan26 (talk) 05:16, 10 August 2011 (UTC)

Cause of earthquake

The intro text says "The earthquake was caused by a sudden surge of magma from the Earth's mantle.[3]". However, the archived reference table does not address this particular issue. How sure are we of this? I would have thought a fault movement would be the most likely cause. Anyway, the article does need a reference which deals with this question. Macdonald-ross (talk) 09:46, 15 December 2011 (UTC)

You're right, that's not supported by source #3. I've moved the citation to the end of the previous sentence, which it's fine for, and added a 'citation needed' tag after the 'sudden surge of magma' sentence. I've had a good look around for a reference that gives this as the origin, but I've failed to find any. Mikenorton (talk) 17:33, 15 December 2011 (UTC)
