6.4 Earthquake in Searles Valley, CA 7/4/19 & 7.1 7/5/2019

[lostngone]

I heard that there is an over 70% chance that there will be another California earthquake, magnitude 6 or higher, as followup to yesterday's quake.

Also as a followup, the city of Los Angeles is going to make a software change. This year they released an app named Shake Alert LA that notifies residents if a quake is starting and is likely to cause damage in Los Angeles county. But people are complaining that it didn't alert anyone to this week's 6.4 earthquake. The reason is that the quake in central California was estimated to register as 4.5 in L.A. county, below the app's "likely to cause damage" threshold of 5.0. Since the quake did in fact cause damage, the city has announced that it will lower the notification threshold.

People will complain either way, we have a tsunami warning system where I live that has a tendency to over alert on the possible affected area and a lot of people get upset because they get the alerts.

Perhaps they should let users set their "alert threshold" as an app preference, from "tell me everything" to "alert me only for the biggest threat."

Both were far stronger feeling here in Ventura Cali and stronger than the 5.3 we had in the Channel Isalnds last August.
I was surprised my Alert didn’t sound for either of these.

btw - the app does need some work. LA should look at Japan and what they have done.

What damage did it cause in LA county?

2 days, no major aftershock. Friday night until Saturday morning sucked, though. All those little aftershocks could be felt all the way out here and it got annoying fast. Even a 2.6 could be felt. If the thing about animals could be 100% true, then that would explain why everyone's pet around here couldn't shut up all week long.

Just saw Dr. Lucy Jones from CalTech on the news giving the rundown on this. She is absolutely the best at breaking this all down so the average person understands what is going on. She is always so calm and reassuring.

I remember seeing her on the news after the 1992 Joshua Tree earthquakes with her baby. I think she did not have a babysitter, so just brought him to work with her and did live broadcasts holding her son.

Now there is someone I'd happily be a groupie for. She's got it all, brains a heart, and can carry an intelligent conversation. Awe.

Felt the one on July 4th and 5th. The one on the 5th was a pretty good one. I am in the Long Beach area. It was no where near as violent of a jolt as what locations closer to the epicenter felt, but it was pretty good. Not to mention it seemed to last a very long time...

Anyone near Ridgecrest? Hope all is well.

Wife and I are in Upland, CA - we felt it enough for it to shake our apartment that we're in (3rd floor). Lasted a good 15 seconds too. Family in Northridge, Pasadena, and further east in San Bernardino felt it really well.

We were in Bakersfield and felt it, a few days before we were in Ridgecrest itself. Felt very weird - water in the pool at the motel was sloshing around.

This before-and-after image was created by geologist Sotiris Valkaniotis using Google Earth and DigitalGlobe. It shows how the ground shifted during the earthquake. Sorry, but I don't know the scale.
