Don’t let ShakeAlert die

-

Experts can’t predict earthquake­s, but they can warn you that they’re coming. For a dozen years, West Coast scientists working with the United States Geological Survey have been developing an earthquake early warning system — called ShakeAlert — that could provide anywhere from a few seconds to a few minutes of warning not only about the shaking that’s imminent but also about its intensity.

That’s enough time to stop a train in its tracks, let an elevator open at the nearest floor or warn your dentist to pull the drill out of your mouth. But just as a pilot program for the system is ramping up, President Trump’s budget would eliminate $10 million in federal funding for it and end the U.S. Geological Survey’s involvemen­t in it. That would be a colossal mistake. Pulling federal money and federal scientific support would not just slow the ShakeAlert project, it would likely kill it altogether.

The system received $10 million in state funding this year; in addition, the federal government has put in $23 million over the past three fiscal years. The system needs the continued federal funding to finish building out an already extensive network of ground sensors as well as seismic stations to transmit the informatio­n from the sensors. Eventually it will need money for annual maintenanc­e and upgrading the system’s software and hardware and for researcher­s and other staff.

Early warning systems detect the seismic waves rippling outward from the rupture in the earth, calculate the maximum intensity of the expected shaking and send alerts to electronic devices — smart phones, public address systems, computers, television­s — faster than the seismic waves can travel through the ground. The farther you are from the epicenter, the more time you have between the alert and the shaking. But even a few seconds is enough time to find a place to, literally, duck and cover.

L.A. City Hall is already connected to the system, as is the fire station at Universal City. Of course there haven’t been any major quakes recently in this area. But researcher­s in San Francisco got eight seconds of warning when a magnitude 6.0 quake hit Napa in 2014.

The city of Los Angeles has aggressive­ly supported the system. It invested $5 million to set up a network of 125 seismic stations in southern California that have sensors and transmitte­rs.

The system has bipartisan support among members of Congress from California. They should work hard to add federal funding to a warning system that could save lives and crucial infrastruc­ture.
