5.5 Ridgecrest Earthquake Aftershock Rocks Southern California

A quake measuring greater than magnitude-5 struck east of Ridgecrest around 6:30 p.m. tonight.
The U.S. Geological Survey gave a preliminary measurement of 5.1 magnitude and said it stuck a little more than 10 miles south of Searles Valley at a depth of 6.9 kilometers.
Quake expert Lucy Jones said the quake measured in at 5.5 magnitude, though, and she called it a "large late aftershock."
Yes, an earthquake. A M5.5 at the very southern end of the 2019 Ridgecrest aftershock zone. This is a large late aftershock - do you remember that I said these are common?

Ridgecrest was hit last year by major back-to-back earthquakes last summer. The first quake, a magnitude 6.4, hit on July 4. That earthquake, the biggest to strike the region in many years, turned out to be a foreshock of a 7.4 magnitude quake that struck the next evening.
As she did when the first big Ridgecrest earthquake happened last year, Jones reminded everyone tonight that there's about a 5% chance that a bigger quake will follow.
Jones told us:
"It is indeed an aftershock to the earthquake that occurred last July. It's been 11 months since the main shock."

THE BIG ONE IS COMING. GET PREPARED
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 Ridgcrest quakes last year. To help you get prepared, we've compiled a handy reading list

Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.

Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.
