A mudslide caused by excessive rain occurred about 55 miles north of Seattle Sunday. It killed several people and caused extensive property damage. This is nothing compared to what will happen when Mount Rainier blows it's top. The rock on the slopes of this volcano is very unstable and when it rumbles it will make the mudslides of today pale in comparison.

In that part of the world, I would have thought the Cascadia subduction zone was a bigger concern.

They are all related, but the big event will be when Mt. Rainier blows it'd lid and the Tacoma Seattle area becomes history.

When Rainier blows Seattle could get a lot of ash but the entire Puyalup river valley down to and including Tacoma could get burried under a massive lahar, a mud flow. All of us in the Puget Sound region could see a lot of ash depending on the wind. The prevailing winds are usually west to east so it is Eastern Washington that would probably get most of the ash as it was with St Hellens in 1980.

Excessive rain in Washington State, surely you jest. LOL!

We woke up years ago thank you.

The material I read, and I cannot at the moment recall what or where it was, indicated that the next big Cascadia earthquake could be one of the biggest in history. The last one in 1700 was probably about a 9.
It also though that the buildings in coastal cities of Washington and Oregon would not be able to withstand an 8, that's about what hit SF in 1906. Add that to the flooding which would probably occur on most of the coast from CA to Canada and you are in for a very big disaster. And as stated above if Mt. Rainer erupts it will "only take out" the area to the south of Seattle.

Given the reported instability of Mt.Rainer it is possible that "the big one" would set that heap of rubble off, just adding to the woes of Washington State and the whole West coast :-(

We had a pretty good shaker of 6.8 here in 2001 with the Nisqually earthquake. It put cracks in most of the homes here including ours.

All jest aside the mudslide is a tragedy and we have friends that have not check in from that area.

I am sorry but there are places I will not live in and or by no matter how beautiful and peaceful and serene they seem. Yes you could say I am taking my chances living here in the shadow of several mountains but I also take a chance every time I drive on the byways to the market.

That is scary when the very ground moves out from under you. I felt the earth quake that damaged the Washington Monument; it wasn't that big but my house moved and I heard a crack. I really thought something was pushing on my house. When I went outside the ground was moving. This was my first quake and my mind couldn't grasp what was happening. I sort of know how these people must have felt. Imagine being in bead one minute then instantly hundreds of feet away under mud.

Some day the Rocky Mountains will look like the Applications; this is how it happens.

Hopefully the wind is not blowing your way that week or it will be in your back yard for sure.

On a side note; have you seen any of the pottery glazing done with St. Helen's ash or any volcanic ash for that matter? ;^)

Cool stuff...

I watched NOVA on PBS last night, it was about Mt. St. Helen. For such a large blast only 57 people died but unlike the mud slide there were many warning to get out. There was a warning this slide could happen but like the warnings the Jersey Shore will someday be sweep into the sea people don't/can't change their lives because of a someday event. "We've known it would happen at some point,"
A scientist who documented the landslide conditions on the hillside that buckled had warned in a 1999 report filed with the U.S. Army Corps of Engineers of "the potential for a large catastrophic failure,"

Luckily Mt. St. Helens is located in a fairly remote part of the state. Some residents decided not to heed the warnings and some of those who died were scientists observing the mountain for signs of an eruption.

I think Mount Baker is more of a concern as it is almost certain that the ash will blow up this way.

Nah, IMO the prevailing winds are down the Frasier river or from the west so you are probaly safe atleast from Baker.

I live just south of Tacoma. The predominate weather direction is southwest to northeast for us.

1980 Mount st helens ash distribution pattern.

If the pop is big enough and high enough it will go around the world and give every body a dose of ash. LOL

The Juan Defuca plate is the extension of the San Andreas fault off the Washington and Oregon coast. A Makah fishing village was buried in [place in around 1700s near Port Angele's it is surely buried by a tsunami.
