Expected Mega-quake could Kill 15,000 in 30 Minutes



The June 7-10 exercise is called Cascadia Rising.

It is named after the Cascadia Subduction Zone — a 800-mile-long fault just off the coast that runs from Northern California to British Columbia.

Recent subduction zone earthquakes around the world underscore the catastrophic impacts we will face when the next Cascadia Subduction Zone earthquake and tsunami occurs:
  • Indonesia (2004): M9.1 --- 228,000 fatalities
  • Chile (2010): M8.8 --- 500 fatalities
  • Japan (2011): M9.0 --- 18,000 fatalities

Seismologists and federal officials are predicting a devastating earthquake in the Pacific Northwest along the Cascadia Fault line that could, theoretically, leave tens of thousands of people dead and even more displaced. RT’s Simone Del Rosario speaks with seismologist John Vidale about the possibility of a disaster striking.
The Cascadia Subduction Zone off the coast of North America spans from northern California to southern British Columbia.

The Cascadia Subduction Zone off the coast of North America spans from northern California to southern British Columbia. This subduction zone can produce earthquakes as large as magnitude 9 and corresponding tsunamis. Scientific evidence indicates that a magnitude 8.0-9.0 earthquake occurs along the 800-mile long fault on average once every 200 to 500 years. The last major earthquake and tsunami along the fault occurred over 300 years ago in 1700.

‘Doomsday EQ drill’ in Northwest, largest in US ever: Mega-quake could kill 15,000 people in 30 minutes

by The Extinction Protocol
June 2016 - PORTLAND — Imagine a devastating earthquake and tsunami have cut off Pacific Northwest coastal communities. Phone and internet service have collapsed. Ham-radio operators living on the stricken coast fire up their radios, contact emergency managers and report on the magnitude of the disaster so that no time is wasted in saving lives. This is the kind of scenario that will be rehearsed during the second week of June in a massive earthquake and tsunami readiness drill that has been developed by the U.S. government, the military, and state and local emergency managers over the past few years to test their readiness for what — when it strikes — will likely be the nation’s worst natural calamity.

The June 7-10 exercise is called Cascadia Rising. It is named after the Cascadia Subduction Zone — a 600-mile-long fault just off the coast that runs from Northern California to British Columbia. “This is the largest exercise ever for a Cascadia break,” said Lt. Col. Clayton Braun of the Washington State National Guard. Braun has been a key planner of the doomsday drill, which is being overseen by the Federal Emergency Management Agency. 

Federal officials say about 20,000 people will be involved in the disaster drill, representing various federal agencies, the U.S. military, state and local emergency response managers across the Pacific Northwest, Native American tribes and emergency management officials in British Columbia. One main goal of the exercise is to test how well they will work together to minimize loss of life and damages when a mega-quake rips along the Cascadia Subduction Zone and unleashes a killer tsunami.
Awareness of the seismic threat looming just off the Pacific Northwest dates back to the 1980s, when researchers concluded that coastal lands long ago had been inundated by a tsunami. Research also indicated that a tsunami that was documented in Japan in January 1700 originated from the Cascadia Subduction Zone, also known as the CSZ. Research suggests that the CSZ on average produces magnitude 9.0 quakes every 500 years, but big quakes have been separated by as few as 200 years and as many as 1,000. So it is impossible to predict when the next monster quake occurs. However, tectonic stresses have been accumulating in the CSZ for more than 300 years and seismologists say it could rupture at any time.

More than 8 million people live in the area that is vulnerable to the Cascadia Subduction Zone. It contains the most heavily populated areas of the Pacific Northwest, including Seattle and Portland, as well as Interstate 5, one of the nation’s busiest roads. Coastal towns are especially at risk. Studies have forecast that while 1,100 people could die from a 9.0 magnitude quake, 13,500 could perish from the tsunami that would slam into the coast within 15 to 30 minutes after the shaking begins.

A scenario document written in preparation for Cascadia Rising exercise states “the scale of fatalities across the coast may overwhelm the resources of local governments.” Whole towns along the coast may disappear. Hospitals could either collapse or be too severely damaged to handle casualties. All across the region between the Pacific and the Cascade Range, bridges and roads could be destroyed, fuel supplies and communications disrupted, and buildings and crucial infrastructure may sink into soil that’s been liquefied by the intense shaking. –Seattle Times

    " Ham radio operators living on the stricken coast "
    Kind of a non sequitur , donchya think ? Didn't everything within MILES OF THE COAST get WASHED AWAY by the " devastating tsunami " ? OH NEVER MIND !
    LOSING Seattle/Tacoma , Portland & surrounding area and ALL POINTS SOUTH down the coast down to BAJA ( save for the few Hawaiian natives selling genuine Polynesian food there ), would be an IMPROVEMENT. BRING IT ON ! ! !
