Why LA's early warning system didn't send an alert before the 6.4 magnitude quake

Why LA's early warning system didn't send an alert before the 6.4 magnitude quake Did Los Angeles' ShakeAlertLA smartphone app fail to provide an earthquake early warning? Los Angeles residents were asking that question after Thursday’s earthquake that was felt through 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 app was only designed to alert users of cellphones physically located in Los Angeles County if there was at least “light shaking,” or level 4 on the Modified Mercalli Intensity Scale, expected for Los Angeles County.

Southern California isn't doing enough to fix earthquake-vulnerable buildings, expert says.
"I don't want to frighten people," one expert said. "But I think it's important to be transparent. This is a real issue." O'Dell estimated that half a million people likely call these structures home. That estimate is drawn, in part, on a recent survey done in the city of Los Angeles that found roughly 12,000 soft-story structures built before 1978. Extrapolating out across a county that has dozens of cities and a population of more than 10 million, O'Dell said the area could easily have double that number.
