Sunday’s quake: UC Berkeley scientists gave 10-second warning; a wake-up call for emergency preparedness
Unbeknownst to some, the magnitude 6 Napa County earthquake that woke many people up in Berkeley at 3:20 a.m. on Sunday morning was “predicted” by scientists in our very city with a 10-second warning about the trembler.
The alert was issued by the UC Berkeley Seismological Laboratory’s ShakeAlert earthquake early-warning project. The demonstration warning system provided 10 seconds warning (as shown in the video above) at laboratories in Berkeley, San Francisco, Oakland and San Jose. It preceded a quake that was the largest to hit the San Francisco Bay Area since the devastating 6.9-magnitude Loma Prieta earthquake 25 years ago in 1989.
ShakeAlert is not a predictive tool — predicting quakes is still beyond the expertise of even the most eminent seismologists; rather it is being developed to act as an early-warning system to help minimize quake damage. For example, with even a little warning, BART trains could slow down to avoid derailment, utilities companies could shut off gas vales to prevent fires, elevators could be stopped and their doors opened at a floor, and surgeons could stop operating. … Continue reading »

People took to Twitter almost immediately after the quake, which was felt around the Bay Area and lasted a significant time. It was described by one person as “a long roll.” … Continue reading »
