I'm an EQ geologist that is happy in a trench with a fault & my family with two minerals the hubs in there with me. Born at 334.9 ppm CO2 concentration.
FOP Ridgecrest! M7.1 stop today and 6 years ago with Olivine for scale. Scarp is modified by channelized rainfall but offset berm is still visible!

I did but the test EQ was in Berkeley? KCRW announced it if you happened to be listening.

These little earthquakes in Berkeley are reminding me that the ShakeOut drill is happening in ~25 minutes!

Felt that earthquake! Very lightly though - so much that I had to check our house seismometer!

@lastweektonight.com John, absolutely love you and your analyses - top notch and the best! But … you might want to work on your resting pause faces. Trust me when I say that my kid had to poop and I had to go support her and this is where I landed.

Chris modified this figure from a Temblor article which is modified from Shirzaei & Burgmann (2013) showing location of this very early morning's M4.3 earthquake in Berkeley along the Hayward fault. It looks like it happened in the zone where it goes from creeping zone to locked zone.

Seriously felt that one - woke 3/4 of us up! From our house seismograph.

M2.4 EQ in Oakland! Didn’t feel it b/c we 🏃♀️🏃♂️ errands, so instead our house ChatGPT user (Chris) asked about energy analogies for an M2.4: 1)🐜 420 quadrillion marching ants; 2)🦍 7,900 sprinting gorillas; and 3)🐋 8.4 sprinting blue whales! 0.4=whale front or tail? Screenshot of calculations below.

The revised focal mechanism is RLSS. Wikipedia has a nice map with the fault sections on it and Ray thinks that is was the section that hasn’t ruptured since 1839.

I learned so much today at the Taber Drilling class in the gorgeous Capay Valley; I was in awe of the breadth of experience and expertise of our presenters. Excellent program! And now I get to enjoy the tiniest sliver of the crescent moon, Venus & Jupiter setting on the flanks of Mt. Tam. #grateful

I see it just gives abs “ocean” option for background and not terrain or satellite.

Didn’t feel the pair of M3 earthquakes in Hayward while sitting at my desk, but others did and so did our house seismometer! BTW, what happened to the background map for USGS recent EQs page?

So not on/near the CT and about 1.25 miles east of the sag pond we visited on the Concord fault just south of downtown.

Oooo. It’s strike slip! Wonder how much the location will change. #runningtocomputertoplotonmymap
