March 10, 2005 Newport, Oregon – An abnormally large number of small earthquakes swarmed in the Juan de Fuca region off Vancouver Island, British Columbia, Canada, between February and March 4. Then on March 8, 2005, Mount St. Helens released a 30,000-foot-high plume of gas and ash. Offshore, U. S. Navy hydrophones picked up at least 4,000 low magnitude rumblings over six days, which provoked university and NOAA scientists to recently dive down to the sea floor to check out what was happening. Of all the seismic regions off shore around the continental United States, the Juan de Fuca ridge is one that could have a subduction event in which plates violently slide over each other as they did in the huge December Indonesian event. If that did happen in Juan de Fuca, there could be a very large tsunami as well.Click for report.
