#New Volcano ?
6 messages in this thread
Hi …
I don't actually have a reply to this, although I'm going to try to find out.
Meanwhile, if you do find out, I would really like to know. The Juan de Fuca
subduction zone seems to be younger than most subduction areas (10,000,000
years … just a kid). Other such small fry have produced some really violent
earthquakes as well as ubiquitous vocanoes, but this one doesn't seem to have
done so, according to some. Others cite geological evidence of Tsunamis coming
ashore from sea quakes. An undersea volcano is an interest proposition …
Do you have coordinates for this mysterious little puffer? If so, please
forward. I will try to get to the USGS when they're not quite so busy and see
what they have to say. If I find something, I'll send it right on back to you.
Meantime, reference is made to two articles on the Juan de Fuca from the
magazine database accessible under Reference.
First is reference #A5101290 by Richad Monastersky.
Second ref is: #A10688560, no author stated.
Both are out of Science News.
I was in Oregon and Washington a few months ago, and when you see these volcano
peaks rising up out the clouds, and then have a look at Crater Lake, it
certainly does bear witness to the immense forces involved. …
————————- The Strait of Juan de Fuca, an inlet of the Pacific
Ocean, separates Vancouver Island in British Columbia from the state of
Washington. The strait is about 161 km (100 mi) long and 18-27 km (11-17 mi)
wide; the U.S.-Canada border runs through the center. The strait links PUGET
SOUND and the Strait of Georgia with the Pacific Ocean.
Hi …
Thanks for the info. …
My main concern here isn't particularly the Strait, though I would love to sail
it sometime, but rather the Juan de Fuca plate, with its ridges and transform
faults and subducting regions that stretches out from just south of the Queen
Charlotte Islands to northern California. Its complex and unpredictable
relationship with the Pacific Plate and the mainland has me wondering if my
son, who goes to school in Oregon, is in for a shake sometime this year or
soon. But hell, he lives in San Francisco generally, so what am I worried about
Oregon for?
When I was there recently I took a trip down the Columbia River Gorge, which
was magnificent, and also spent some time in the mountains. Some of the
national forest folks said that St. Helens is expected to erupt again within a
hundred years because it has a very active magma chamber down there. Also, when
you look at the remnants of Mt. Mazama, the explosion of which sent ash to
Mississippi and gave us the deepest lake on Earth, you can't help but wonder if
this small, young plate is going to have something significant to say despite
its youth.
So … I was really talking about this plate, and wondering if an undersea
volcano was literally letting off some of the steam that would otherwise wind
up on land in the forms of earthquakes and volcanic activity, which is why I
wanted to know where this postulate undersea volcano was. … Or, if we'd get
another Surtsey soon!
Thanks for writing …
Morgaan,
I got this info from a curious, but probably reliable source, a local service
station owner. He said that he had heard it on the National TV news. The news
cast said that the new volcano was located approximately 230 miles off the
Oregon coast. I am the one, based on this crude location, that presumed that
it must be on the Juan De Fuca Ridge. If not there, where else?
Thanks for the help, Bruce
Dear Bruce,
Many thanks. I will go get my scuba gear …
Will let you know if I get anything. Does a woman's heart good to find a new
volcano!

Did you fly over St, Helens? That gives a graphic picture, even 13+ yrs later.
I live about 150 air miles north and felt the shock wave when it blew.
