The following are technology issues that need to be addressed in the United States.
Earthquake detection and warning systems — like Japan’s that worked effectively during its latest quake — are still just on the drawing boards in California. The Cascadia Subduction Zone that runs from British Columbia to off the coasts of Washington, Oregon and California is a perfect candidate for such a warning system. Because of its extreme length there could be minutes of warning for portions of the quake zone.
The existing tsunami warning system is not currently effective for a quake that is this close to the coast. Having an earthquake detection and warning system tied into the existing tsunami siren warning system would provide a dramatic improvement in warning capabilities and give people a head start on escaping any tsunami generated by a subduction zone quake.
