Heading down to LA to visit family for the holidays and the 5 is closed - eek! Detouring to eat dinner at Harris Ranch - first time for everything. :)
Holy moly. Landslide ruptured buried gas line which caused an explosion (apparently?) and now a major N/S artery from Central Cal to SoCal is still shut down.

Definitively felt my tuchus wiggle on the couch and heard our house shake after this M3.9 earthquake in San Ramon. Didn’t feel the M4.0 last night at all. Wondering if the magnitude will end up higher? earthquake.usgs.gov/earthquakes/...

October 2025 was the warmest October on record for the #Arctic. Arctic sea-ice extent is currently the lowest on record for late November. My newest 'climate viz of the month' summarizes some of this latest data: zacklabe.com/climate-viz-...

Did you know that scientist don’t really use the Richter scale anymore? The most common magnitude scale used these days is called the “Moment Magnitude” scale. Here’s more info 🧪

Happy Thankssfhusihfsudfhd ...M4.3 Earthquake in San Juan Bautista plotted with Qfaults and historical seismicity 1984-present (Waldhauser's catalog). I wasn't planning on Shake-n-bake today!

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!

@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.

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?

I quickly put together a seismicity map for the region of today’s M7.4 Drake passage #earthquake. An uncommon location for a large thrust event in a tectonically complex area. 🧪⚒️

People having been asking: "Are these cuts really that big of a deal? Could people really die?"
And the answer is: This exact situation, during a major hurricane/flood/tornado/wildfire event, is precisely how that would happen.
