An earthquake with a preliminary magnitude of 4.1 struck near Westlake Village at 1:03 p.m., according to the U.S. Geological Survey. Shaking was felt as far as Santa Clarita and Huntington Beach.
No reports of damage or injuries so far.
The quake was quickly followed by three smaller temblors in nearby Malibu, each between 2.5 and 3.0 magnitude.
A ShakeAlert was issued.
As Jacob Margolis, LAist's resident earthquake expert has previously noted: ShakeAlerts are part of California's robust earthquake early warning system, and can give you a 10-plus second heads up when a quake is on the way. Using a widely distributed network of seismic sensors, it can detect, estimate the size and direction of an earthquake and transmit a warning to you, sometimes, before the waves get there.
The MyShake app from UC Berkeley allows you to adjust warnings based on intensity, so if you want to know about the tiniest of temblors, get ready to be inundated.
