UW Tests New Earthquake Early Warning System

UW Tests New Earthquake Early Warning System

Washington and Oregon will be covered by software program which opens testers’ computers and shows the earthquake epicenter, its magnitude, and the time before shaking. The trials will run about a year.

The trial group includes Boeing, Microsoft, Sound Transit, Providence Hospital and other hospitals, transportation agencies, utilities and emergency managers. They are meeting Feb 12th to implement the trial.

In Japan, similar earthquake alerts have been used to slow bullet trains to prevent derailment, trigger automated earthquake and tsunami alarms in schools, and shut down expensive manufacturing equipment to avoid damage due to shaking.

Some 240 seismometers are linked in Washington and Oregon. The new early warning system being tested will create an automated alert as quickly as four seconds after a quake’s fast-moving but harmless P wave is first detected. That could mean a few seconds to more than a minute’s warning before people would start to feel the ground-shaking S waves.
