This 4-day exercise tested the emergency management community’s approach to a disaster in the Cascadia Subduction Zone, using an earthquake and tsunami scenario.

Recent FEMA publications tell us that science points to a large 8.0 – 9.0 magnitude Cascadia Subduction Zone (CSZ) earth-quake ripping across the 800-mile CSZ fault line on an average of once every 200 to 500 years. The fault zone follows the coastline of the Pacific Northwest states somewhere between 60 and 100 miles offshore. The last major CSZ earthquake and tsunami occurred in 1700.

When the next CSZ event happens, there will be significant loss of life and infra-structure damage. Normal means of communications, vital to response operations, will be cut throughout the Northwest. It’s then that Amateur Radio has to work and must respond. A CSZ event will be a disaster of national scale that will require many years of recovery. The major earth quakes in Japan, Indonesia, and Chile serve as a stark reminder of what is likely to happen.

There is a 17 to 20 percent chance that northern Oregon will be hit by a magnitude-8 quake in the next 50 years.

For about the last 30 million years, a small tectonic plate named Juan de Fuca has been sliding under the far vaster North American plate into the Earth’s mantle. Today, this mostly happens without anyone’s notice—even though it causes minor, near-undetectable earthquakes about every 300 days—but sometimes the pressure pent up is released suddenly and catastrophically.

This is what happened on January 26, 1700. The plate slipped, and a magnitude-9.0 earthquake resulted, devastating the coast of modern-day Oregon and Washington. According to one story, an entire First Nation on Vancouver Island, the Pachena Bay people, died in flooding overnight. And the quake triggered a tsunami that rode across the Pacific Ocean for 10 hours before slamming the east coast of Japan, where merchants and samurai recorded flooding and damage.

As hundreds of thousands of Americans now know, this could happen again—except now, millions more people inhabit the Pacific Northwest. The existence of the Cascadia subduction zone, and its power to jolt the region with a “really big one,” was revealed to mass audiences last year by the writer Kathryn Schulz in a barn-blazing story for The New Yorker.

However, it now seems these coastline-altering events happen more frequently than previously thought. A team of researchers led by Chris Goldfinger, a geologist at Oregon State University, has found evidence that at least 43 major earthquakes have occurred in the last 10,000 years. That number is slightly larger than previously estimated, which means that—over the long time period—it significantly alters the likelihood of any one event occurring.

Seldom used back roads outside Astoria and Seaside could offer a lifeline in a Cascadia earthquake.

Clatsop County Public Works is exploring ways to create alternate and evacuation routes and have identified several possibilities, including some that are currently gated off on private timberland.

Clatsop County isn’t as far along in prepping for a Cascadia earthquake and tsunami as Tiffany Brown, the county’s emergency manager, would prefer. But that’s nothing to be ashamed of, given that the region only realized the full magnitude of the threat within the last decade.
