Cascadia Rising

On Thusday, people across the state will be taking part in the Great Washington ShakeOut. It’s an earthquake drill.  You might remember this sort of exercise from grade school, but kids aren’t the only ones who need to know what to do.

A major earthquake-preparedness drill takes place this Saturday in Seattle. It’s called “Hubs and Spokes” and this time, the emphasis is on emergency communications.

The report cards are in and it's not pretty if you worry about how you'll fare after a magnitude 9 Cascadia megaquake and tsunami. Washington and Oregon's emergency management divisions have now published after-action reviews of last June's multi-state disaster drill called Cascadia Rising .

As part of earthquake preparedness, Seattle has identified community hubs where people can gather after a quake. On Saturday, the hubs will be activated for an exercise. But, there are no hubs in some of the city’s most popular neighborhoods, including Belltown, Downtown, the Central District and Capitol Hill.

Imagine being on a rural island when a major earthquake hits off the coast. After five minutes of shaking that registers 9.0 on the Richter scale, devastation is all around. Food, water, medicine and fuel are in short supply.  Along with power and phone service outages, all bridges and ferry connections are down.
