Once again drawing my paranoid mind back to Eve's favorite movie San Andreas, a pair of theoretically unrelated earthquakes struck hundreds of miles from each other Tuesday evening within just 13 minutes. The first hit offshore, 61 miles northwest of Eureka, which would be in the San Andreas Fault zone, and was recorded at 5:35 p.m. Tuesday with a preliminary magnitude of 4.9, as the SF Chronicle reports. The second, with a magnitude of 4.4, hit 6 miles northwest of Rialto in San Bernardino County, and was recorded at 5:48 p.m. It was widely felt across the county.
The Southern California quake, while not far from the San Andreas Fault Zone, appears to be more along the San Jacinto Fault. There was an immediate aftershock there of 3.8 magnitude.
Both areas have been seismically active lately, with the same area off the coast of Eureka experiencing a 4.8 magnitude quake Monday evening at 7:35 p.m., and the Rialto area has experienced four quakes of 3.0 or greater in the last 10 days, as the LA Times reports.
These modest but similarly timed quakes come as a newly published study is rethinking how the San Andreas functions, and just as Congress approved another $8.2 million for a statewide earthquake early warning system, which has been in the works for several years and is currently in a testing phase. It's expected to cost over $38 million to complete, and will require $16 million a year in operating costs, but it will provide Californians with critical extra seconds of warning, via text messages and other alerts, before a major quake strikes also allowing train operators to stop trains or get them out of tunnels.
Again, these quakes are, in all likelihood, way too far from each other to be related. But do you trust the state of earthquake science? Because I don't.
Here's your friendly reminder to get your earthquake kit together.
