Default Possible new underwater volcano off WA coast

First there were several mag. 4 quakes off Vancouver Is, Canada, which I think are in the same area but I haven't confirmed that yet. Then this news report came last night. This is exciting but it will be a while before we get any scientific reports. There have been other volcanoes at the San Juan de Fuca plate edge. But it is always exciting to have a new one as each time we seem to have better monitoring equipment.

Quote:
On board the research vessel Thomas G. Thompson, a scientific rapid response team was en route Saturday to check out some underwater earthquakes.

"We've had about 3,000 earthquakes reported," said Dr. Ed Baker of the National Oceanic and Atmospheric Administration (NOAA)

The scientists believe an underwater volcano is erupting along the undersea Juan De Fuca Ridge, some 300 miles off the coast of Neah Bay.

The underwater earthquake swarm began last weekend and scientists say it produced nearly 1,500 small quakes in the first 36 hours.

Would it be too speculative to invest in real estate on the new volcanic island that may form? :wink:

Well that hasn't seemed to have affected the price of land in California. :P

Well...California is a little less wet than the potential off-shore real estate.

Would the volcano be in US or Canadian territory?

From what I've read, the Pacific Northwest is as vulnerable to earthquakes and other catastrophic events as California is. Being at the boundary of a continental and a Pacific plate is very helpful if you want to build a new volcano. Fascinating story. I'll be watching the news for more.

It would be Canada's.

However, that area has calmed down. The activity is now off the coast of Oregon. In the last two days there has been a 4.3, 4.7, 5.1, and 5.2 off the coast of Oregon.

Is this a sign of future activity/trouble for the Pacific Coast? Does this increased activity make it more likely there will be a major "event" in a current, active volcano (Mt. St. Helen's for example) or along a major West Coast / Alaskan fault line? Or is there little geological relationship here?

Just trying to separate the woo-woo warnings from the scientific facts! :roll:

I don't know, but it would be neat if there's a hydrothermal vent out there. Those are great!

Pretty much normal goings on for that region of North America.

Historically, the areas are active.

Coast of Oregon

Coast of Vancouver

Within a 100 km radius of one of the Vancouver quakes, there has been 345 earthquakes 2.6 and greater since 1973 (NEIC catalog search).

There is a whole ridge of vents out there.

Just trying to separate the woo-woo warnings from the scientific facts! :roll:
While the volcanoes are all related to plate movement, these underwater eruptions are from the plate's edge where it is spreading apart. The Cascade volcanoes are the result of the subducting edge of the plate re-melting as it sinks below the Earth's crust. The plate movement is somewhat constant so this doesn't represent an increase in activity.

There have been frequent undersea volcanoes in this region. NOAA and the U of WA researchers are hoping to view one in action. So far, they've gotten there after the fact.

If its 300 miles off the coast, it would be in international waters. Until it breaches surface (probably unlikely) and someone claims.

I dunno, the laugh I got about the platoon sergeant and the lieutenant showing off with his pistol was worth the exposure to insanity.

I went to college here in Olympia, at the scenic Evergreen State College. I was in our poorly-designed dorms when the Nisqually quake hit.

since then, I've become very, very good at explaining plate tectonics to out-of-state students, especially ones from (in the case of one of my friends) Minnesota. unfortunately, I can't deliver the speech to full effect here, because I use my hands to symbolize the plates.

long story short, the Juan de Fuca plate is slowly disappearing under the North American plate. my geology teacher seemed pretty sure it would never completely go under, but that's what's causing the majority of seismic activity around here.

Yeah... And a lot of the lighter elements that have been subducted have risen through the upper mantle and continental crust to form the Cascade range. It's one of the really cool natural laboratories of the world.

I'd love to see the full lecture with the hands and everything. Living through something like that to generate a healthy respect for nature and lots of interest in how it works.

and our government claims that 25% of ozone gasses is emitted by household fires in the garden?

There is an incredible amount of stuff on that site. The volcano is incredible but what I found most interesting was how the island evolved to what it is today. The rounded boulders on the beach are fascinating, (how they evolved to be there, not just that they are round rocks).

Iz all right, had a night of sleep and an ice cream sandwhich. Brain seems to have sustained no permanent damage.
