Two earthquakes struck near Ontario within 30 minutes on Saturday morning, with a magnitude of 3.5 and 3.9, respectively, according to the U.
S. Geological Survey. They were the largest in a series of smaller quakes that continue to rattle the area.
The first quake, a 3.5, struck at around 10:05 a.m.
It was followed by the 3.9, about 30 minutes later. Quakes of those magnitude produce weak shaking.
No immediate reports of injury or damage. A shake alert message was sent. There's a roughly 5% chance that a bigger quake could strike some time in the next few days.
Although seismologist have advised us it would likely be only slightly more powerful. This is the standard forecast for all quakes, since the question comes up frequently. We don't want to scare you, but the Big One is coming .
We don't know when, but we know it'll be at least 44 times stronger than Northridge and 11 times stronger than the Ridgecrest quakes in 2019. To help you get prepared, we've compiled a handy reading list:.
