Did the ShakeAlertLA system fail to provide an earthquake early warning?
Los Angeles residents were asking that question after Thursday
s earthquake that was felt throughout Southern California, when they didn
t get an early warning from the much-anticipated ShakeAlertLA app, released by the city of Los Angeles earlier this year.
Did it fail? Not quite. The ShakeAlertLA smartphone app was only designed to alert users of cellphones physically located in Los Angeles County if there was a decent chance of destruction, with the warning system forecasting at least
light shaking,
or level 4 on the Modified Mercalli Intensity Scale.
What was actually felt Thursday in Los Angeles County, while seemingly scary, was actually not that bad. It was forecast by the earthquake early warning system as bringing shaking too weak to cause significant damage in Los Angeles County, said U.S. Geological Survey research geophysicist Rob Graves.
It didn
t meet the threshold for the L.A. area,
said Doug Given, the U.S. Geological Survey
s earthquake early warning coordinator.
The level of shaking in the city of Los Angeles was not damaging,
Graves said.
Why L.A.’s early warning system didn’t send an alert before the magnitude 6.4 quake
Why didn’t users of Los Angeles’ earthquake early warning system get an alert for Thursday’s 6.4 magnitude temblor?
