Seven more volcanoes

[Matthew5]

When Mt.hood go's much of Portland is in deep trouble...I would not be surprized if a few feet of ash landed on my roof...With rocks the size of my computer landing on everything. It will be a very bad day.

Gulfhills I will explain a caldera as much as I can to you.

Bascially a caldera is a collapse. Image magma rising alright? it makes a chamber deathly close to the surface of the earth. when a hole or tunnel is formed, the magma and pressure "seep" out. as this happens the crust above the chamber needs that magma to hold up. but as the magma gets drained, it leaves a huge sinkhole. the crust above the magma chamber fills in below where the magma use to be, thus creating the Caldera. Yellowstone Caldera is in need of major attention. Animals have been found dead, and co2 levels are on the rise in the sections where the gas is escaping the earth. a big buldge is in the yellowstone lake, and this buldge is called a lava dome. This lava dome is much like a pimple. its an area where magma is presses up, and the crust above it, the earths ground is raised in a hill like structure. when these burst, an eruption happens. yellowstone caldera is so big, that its 1/3 the size of the lake itself, and is actually "tilting" the lake, making the water flood sections of the park. image the eruption sizes. I will compare it to Mt Saint Helen of 1980. Pretend the size of the eruption was a peanut. an ordinary peanut, not the dual peanut shells, but just one peanut. The yellowstone eruption would be a beachball if compared. that is huge, knowing the ash cloud from saint helens in 1980 reached 80,000 feet in 15 minutes. Yellowstone quakes are on the rise in the area under the caldera, and time is running out for this volcano to blast. the intervals were every 600,000 years about for this volcano, and the years are up and we are due for it. If this happens, people will die east of the volcano. The pyroclastic flows, which are avalanche like flows will destroy areas 300 miles from the volcano in 1,200 degrees of superheated ash and rock. It will be terrible. If you think you are safe from that, get away from the ash cloud trajectory. Microscopic images of volcanic ash show that they are really like tin pieces of glass, with jagged edges. that would tear your lungs apart if you dont protect yourself. If it happens today, or tomorrow, or whenever, keep in mind,. if you are in FL, you are safe. Everyone that is in kansas and oklahoma, go to extreme southwestern tx, california, oregon, washington, arizona, will be untouched, the Northeast states, head north to canada, and the northern plains, head into canada. the ash cloud will follow the high alltitude west to east winds, and spread south and north of the site as well, so you would image the size of it, and also where to be safe. New Mexico will not be, must travel to SW texas, or even Arizona, which is safer. With earthquakes, hurricanes, extreme weather, asteroids, why not a volcanic blast from yellowstone? It seems that all this is happening within 1 month, so it's very odd, but keeps the eye on. If you would like to monitor yellowstone, theres plenty of sites online about it. you can look at data of earthquakes, reports of lava dome size, etc.

A Volcano like Yellow stone blown around 70,000 years ago. It was close to cleaning are clock. Afterwards there was around 1,000 human on earth...This from a smaller volcano like Yellow stone that blown around the indian ocean...It will block the sun out for years...Rocks the size of houses or bigger will fly out in maybe get miles if not 10s of miles away from it. Pretty much would look like what happen 65 million years ago.

Oh my gosh - I just don't understand. I can see the logic in people wanting to still live in Florida, even with the risk of hurricanes and such, because there is not always a constant threat lurking there. But to live in a volcano's shadow???? WTH???? Did they not learn anything from the 1980 eruption?
At least with a hurricane you have notice and can LEAVE.
Volcano - you're toast - literally.

I just don't get it.

Well, in Mount Hood's case...it's an extinct volcano....according to the U.S.G.S., the last eruption occurred in 1865. There are several large ski resorts on the side of Mt Hood, as well as campgrounds and resorts galore in the area (not to mention resort towns such as Sandy and Hood River). If Mount Hood ever becomes active again, an explosive eruption could be catastrophic.

Sis's in-law's live in scenic Hood River, Oregon.....almost in the middle between two extinct volcanoes...Mount Hood, Oregon and Mount Adams, Washington. You can clearly see both peaks from their living room.

In fact, even though sis lives in the Portland suburbs....45 miles from the 11,239' peak, on a clear day, you can see Mount Hood in the east....and the view is spectacular. Here's an awesome photo of Mount Hood, taken from west Portland...with downtown Portland's skyline in the foreground:

I wouldn't exactly say extinct because volcanoes are never extinct they are just dormant. The reasoning behind this is because when continents shift they go over hot spots of magma. Kileaua is one of these types going over a hot spot and after severl million years it will cool down and become dormant..

Thanks Tornado Chaser. Great explanation, and verrrrryyyyy scary.

Yellowstone is a caldera volcano. If it erupted it would bury a substantial portion of the U.S. under ash. The devastation wouldn't be epic it would be biblical.

If Yellowstone ever has a major eruption, it'd be a global killer(or close to it).

You watch the SUPERVOLCANO thing on TV?

Considering the seemingly renewed interest in this subject, I wonder if S2K shouldn't consider adding a VOLCANO FORUM to their community?

That view is reason enough to live there!!!!!
In spite of anything that "could" happen...
Hey living in Florida gives you winter days in the 70's while the North shivers. So, you put up with an occasional hurricane to live in paradise.
People in Portland can live with the threat of a dormant volcano coming active to have THAT view!!!

a caldera is basically a huge crater like thing. Yes, Yellowstone would probably obliterate the plains and rockies if it erupted. However, it wouldn't end the world. Ash would probably fall on the East Coast, if it was big enough maybe even Europe.

SouthernWx-- 1974... your sis wasn't in one of the tornadoes of the April 1974 "Super Tornado Outbreak" was she? Me, too. I've been thinking of starting a Super Tornado Outbreak Veteran's thread (or site?) near the anniversary next Spring for all of us Storm2kers who were there.

I fared well, but was scared out of my mind. I was six that year, and I had SEEN the Wizard of Oz and knew what could happen!!
