Breaking: An earthquake has just shaken Los Angeles. Preliminary reports from the @USGS says it was a 6.6 magnitude quake.

If you're safe, tell us if you felt the earthquake, if you see any major damage and if you received a notification from ShakeAlertLA on your phone.

We'll update this story as we learn more about the earthquake that just hit Los Angeles  https://www.latimes.com/local/lanow/la-me-earthquake-california-shake-quake-20190704-story.html 

If the initial report of a 6.6 magnitude holds up, this will be the first California quake in 5 years that is or stronger than a magnitude 6. Here's a story from @ronlin that explains more:  https://www.latimes.com/local/lanow/la-me-ln-earthquake-drought-storm-20190402-story.html 

While quakes are on your mind, here are some tips for preparing for the next big one  https://www.latimes.com/local/lanow/la-me-ln-how-prepare-earthquake-20170909-htmlstory.html 

Breaking: The earthquake has been downgraded to a 6.4 magnitude. Its epicenter was in the Searles Valley, a remote area of San Bernardino about 100 miles from Los Angeles.  https://www.latimes.com/local/lanow/la-me-earthquake-california-shake-quake-20190704-story.html 

Today's earthquake was the largest in Southern California since the 1994 6.6 Northridge quake, which killed dozens and caused billions in damage. Northridge hit in the center of a populated area, while this quake was located far from the metropolitan Los Angeles area.

The earthquake was based in Kern County which is dealing with a number of emergencies following the 6.4 magnitude shaker

Wondering why you didn't receive a ShakeAlertLA notification?
It's because the earthquake's epicenter was in Kern County and the ShakeAlertLA system is designed to cover quakes that occur within L.A. County.  https://www.latimes.com/local/lanow/la-me-earthquake-california-shake-quake-20190704-story.html 

In L.A. Today's earthquake shook buildings and swung light fixtures. Closer to the epicenter in Ridgecrest, CA, the quake caused some fires and threw merchandise off shelves at stores.  https://www.latimes.com/local/lanow/la-me-earthquake-ridgecrest-scene-20190704-story.html 

If you've got kids who are troubled by today's earthquake, here are some tips on how to talk to them about it  https://www.latimes.com/local/lanow/la-me-edu-kids-disaster-preparedness-20171027-htmlstory.html 

The 4th of July earthquake hit in a relatively rural area, but if a big quake hits L.A. again, many buildings won't be able to withstand the shaking. This story by @ronlin from January explains  https://www.latimes.com/local/lanow/la-me-northridge-earthquake-california-20190117-story.html 

Why didn't you receive a ShakeAlertLA notification?

The app was only designed to alert users physically located in Los Angeles County if there is at least “light shaking.” Today's 6.4 magnitude quake was only registered as "weak shaking" in L.A.  https://www.latimes.com/local/lanow/la-me-earthquake-early-warning-system-64-quake-20190704-story.html 

The towns of Trona and Ridgecrest are the closest to the epicenter of the 6.4 magnitude earthquake. We're sending reporters @r_valejandra and @alexalucina to those areas where there are reports of fires, buckled sidewalks and broken water mains.  https://www.latimes.com/local/lanow/la-me-earthquake-ridgecrest-scene-20190704-story.html 

Here's how earthquake magnitudes work:

For each whole-number increase in magnitude, the seismic energy released increases by about 32 times. That means a magnitude 7 earthquake produces 32 times more energy — or is 32 times stronger — than a magnitude 6.  https://www.latimes.com/nation/la-fg-mexico-earthquake-magnitude-20170921-htmlstory.html
