RE:  Seafloor earthquakes signal eruption off Vancouver Island http://www.fivedoves.com/letters/mar2005/deborah37-3.htm

 

I saw this on yesterday's list of letters (I start at the bottom)... the first thing that popped into my mind was "you've got to tell those people to run!"  I thought this seemed silly, that I would be the one to tell everyone to run... but the Holy Ghost is insistent (I'm so stubborn)... soooooo....

Oregon’s vulnerability to volcanic events varies statewide.  The Cascade Mountains, which separate Western Oregon from Central Oregon, poses the greatest threat for volcanic activity.  Those regions that include the Cascade Mountains are most vulnerable to the effects of a volcanic event. Within the State of Oregon, there are several volcanoes that may pose a threat of eruption; these include Mount Hood, which most recently erupted about 200 years ago, the Three Sisters, and Mt. Jefferson, wh! ich has not erupted for about 15,000 years, but is not considered to be extinct.

Deschutes County is most vulnerable in the Central Oregon Region because the region’s most populous city, Bend, is located here and the greatest numbers of “composite” volcanic mountains are located near the county’s population centers.  Klamath and Jefferson counties are also vulnerable within this region. Other regions are also vulnerable to damage from volcanic eruptions.  If Mt. Hood erupted, the Northern Willamette Valley/Portland Metro Region and the Mid-Columbia Region would both be impacted.  Because of Mt. Hood’s proximity to Portland, the Columbia River, the I-84 freeway, and major dams on the Columbia River, the potential for a large disaster exists.
