Active Terran Volcanoes - Formerly "Mount St. Helens"

Palomar · 2004-10-01 05:54:18

*Anyone else here keeping an eye on the news regarding this volcano? (Mt. St. Helens) Yesterday scientists said there's a 70% chance it will erupt. I can't recall actual figures of how many times per minute there are tremors and etc.

I remember May 18, 1980 quite well (and not just because it was my 15th birthday). That volcanic eruption was terrible; over 50 people died as a result, all that ash...and thousands of pine trees flattened down like toothpicks.

Really hope it only has a case of indigestion and then quiets down again. Anyone here have relatives/friends in the area, or are you yourself close by?

*First time in 18 years. I don't recall *that* most recent event [ ??? ] and it must have been similar to the current eruption, because I don't remember.

1980 though...whoa.

Hopefully this'll be the last of the current activity.

*Tourists instructed to get out ASAP. Predictions that an eruption resulting in loss of life and property is pending.

News is changing rapidly on this volcano. Just this a.m. the "line" was relative calm, nothing much to worry about.

Saw on TV news last evening people milling about at a scenic overlook, taking photos, watching the ash and smoke billowing up. :-\

This latest headline...yipes (again).

*Volcanic blue moon:

From spaceweather.com (who is hosting the photo):

***
According to modern folklore, a Blue Moon is the second full moon in a calendar month. Most months have only one. A Blue Moon, by that definition, isn't blue; it's just surplus.

On Oct. 2nd, Ryan Tiedeman at Bonney Lake, Washington, saw a moon that was really blue. "At first, when the moon was near the horizon, it looked yellow-white. As the evening continued, the moon climbed higher and moved south--toward Mount St. Helens. That's when the blue tinge appeared." Tiedeman is an experienced moon photographer...

The key to this blue moon could be Mount St. Helens, which is now spewing huge plumes of ash and steam. Sometimes volcanic aerosols act like a color-filter. In recent years people have seen blue moons after the eruptions of El Chichon in 1983, Mount St. Helens in 1980 and Mount Pinatubo in 1991.

Sky watchers in northwestern North America should be alert for more blue moons as volcanic activity there intensifies.

P.S.: Actually, the moon in that pic looks more greenish to me. ::shrugs::

http://www.livescience.com/forcesofnatu … Scientists amazed at dome growth

*Wow. They give a really good descriptive, too, all throughout the article.

An unusually smooth and swiftly growing lava dome within the crater of Washington state's Mount St. Helens volcano is an extraordinary and perplexing event with an unknown outcome

"There's a truckload of hot rock coming out of the mountain every second," said Dan Dzurisin of the U.S. Geological Survey. "We're scratching our heads about it."

Inside a crust about 10 meters (33 feet) thick the dome is loaded with magma, scorching molten rock. The whole structure is pushing its way south as it grows, "bulldozing its way into the glacier," Dzurisin said, "shoving it out of the way, cracking it, lifting it."
The scene looks a bit like a train wreck, with colossal chunks of ice angling in every direction.

John Pallister has been down there. More than once. He gets dropped off by helicopter so he can explore the dome up close, touch it.
"It's a rather dramatic terrain," said Pallister

*Yeah, I'm sure that's an understatement. Would be fascinating to be there, but I'd be too...well...*bwak, bwak, bwak!* :laugh:

Says the sides of the dome are as "vertical as a spine" in some areas. Geez. Wish they had more pics!

*Anyone else here keeping an eye on the news regarding this volcano?

*To answer your original question: Apparently not. Teehee.

http://www.livescience.com/forcesofnatu … .html]Dome building slows

The new lava dome has a total volume of 44 million cubic yards.

There was an explosion on the 16th of January which destroyed a camera and measuring equipment that'd been placed in the crater. Otherwise, all news reports I've read/heard seem to indicate the worst has passed (for now).

By the way, I heard on a Discovery Channel special this weekend that Mt. St. Helens is *the* major player in the chain of volcanoes forming the "Ring of Fire" in the Pacific Ocean regions.

http://www.livescience.com/forcesofnatu … ml]Kilauea wowing tourists

Nice, crisp photos in the link. Recently saw (on Discover Channel) a special about Kilauea. The volcanic activity there is so varied. Maybe it's that way with all volcanoes (I've never lived near one, haven't seen any activity first-hand)...

Sprays of lava, like a fountain going off, resulting in cascading curtains; slow, trundling globs of lava crawling along (so slowly scientists can walk right up to the flow and poke at it with a stick or instrument of some sort); dripping lava, like in the photos -- falling into the ocean; undercurrents (visible through holes) of lava which flow in steady streams or via swiftly-moving rivers of the stuff.

*Image from NASA's Terra spacecraft, obtained February 24. The volcano's name is "Klyuchevskaya." Its peak rises 15,584 feet/4750 meters. Is in northeastern Russia.

The lava belcher is also the region’s most active volcano. In January 2005, multiple steam and ash plumes – along with atypical seismic activity – suggested that Klyuchevskaya was again ready to speak.

On BBC 1 this sunday/monday there is a factual drama called Supervolcano to be shown. It was planned for earlier this year but due to the Tsunami it was delayed.

It is from the same team that brought us Space Odyssey and is about what would happen should the Yellowstone Supervolcano go off and what effects it would have to the people who live nearby and in the world around. Apparently it has very good special effects.

Spectacular Eruption from Mexican Volcano
March 10: MEXICO CITY (AP) _ Western Mexico's Volcano of Fire spewed hot lava and rock Thursday, the latest in a series of spectacular but non-threatening eruptions in the past few weeks. The volcano near the city of Colima, 430 miles northwest of Mexico City, unleashed a column of smoke and ash along with a flow of burning orange lava on Sept. 29. Since then, scientists have reported nearly daily eruptions from its 12,533-foot peak. The eruptions have been caused by seismic activity, and scientists can't predict how long they will last. The activity has sometimes left a light coating of ask on nearby communities, but officials say there is no immediate danger.
A major eruption in 1999 sent glowing rock down the volcano's slopes and fired a plume of ash more than five miles high. In 1913, an explosion created a crater 1,650 feet deep, blasted fast-moving flows of hot ash down the volcano's slopes and rained ash on Guadalajara, 75 miles to the north. Vulcanologists consider the Colima volcano to be one of the most active and potentially the most destructive of the volcanoes in central Mexico. It has erupted violently dozens of times since its first recorded eruption in 1560. -- Associated Press

*Egad...the interaction of cool seawater with pyroclastic flows, reverse surge, etc. A newly-recognized threat scientists are studying.

The expanding turbulent cloud of rock, steam and ash flowed back onto land at temperatures of 600 degrees and speeds of about 130 miles per hour.
The reverse surge reached 1,050 feet above sea level and flowed nearly two miles inland, devastating an area of nearly three square miles that had not been affected by the main eruption.

Killed cows, scorched plants to the ground. Thankfully no humans hurt.

This occurred with the Soufriere Hills Volcano, on the island of Montserrat.

Yellowstone listed as a high eruption threat. I didn't realize there was much chance of it acting up anymore, but they say the large volcanic complex in yellowstone is the 21st most dangerous volcano in the US. Still, there doesn't seem much reason to think it will erupt tomorrow, so maybe not a big deal. I imagine a big eruption there could cause some serious damage though, considering the size of the volcanic complex. Interesting anyway.

A caldera was formed during the eruption; its depth is 850 meters and has become Lake Tianchi (Sky Lake); the border of China and Korea cut across the caldera. Lake Tianchi is considered sacred by the Koreans who live nearby, and they've reported seeing mysterious creatures in the waters of Lake Tianchi.

Mexican Volcano Erupts
MEXICO CITY (AP) -- A volcano in western Mexico unleased its most powerful eruption in more than a decade Monday, shooting ash two miles into the sky and sending burning gas and rock fragments down the slopes. No injuries or damages were reported -- the nearest settlement is about four miles away. Winds blew the ash cloud toward the west, away from the most heavily populated areas.
Tonatiuh Dominguez, a seismologist at the volcano observation station operated by the University of Colima, warned that the peak "`is still in an explosive stage.'' Experts said it was the biggest explosion at the volcano in the western state of Colima since 1991. The Colima volcano, which has erupted violently dozens of times since its first recorded eruption in 1560, is considered to be among the most active and potentially the most destructive of the volcanoes in Mexico. The eruption at the 12,533-foot volcano, 430 miles northwest of Mexico City, was considered larger than one in 1999 but smaller than a 1913 blast that created a crater 1,650 feet deep and rained ash on Guadalajara, 75 miles to the north. -- Associated Press
