Did you feel the M3.1 while you were in Oakland Tim?

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

Did my duty for the Great ShakeOut drill and loved that @kcrw.com reminded me to do it while I was under my table!!!

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!

A full day of astronomical delights: moonset this morning over Mt Tam and sunset just south of Mt Tam this evening

That's terrifying!!!!! Thank goodness the bicyclist walked away; lucky. I always try and take Milvia through there rather than Shattuck. Was it at Shattuck and University?

Half moonset over Mt Tam this morning

Moonset over Mt Tam this morning

Loving weather wonks texts; the map with predicted totals would be an awesome addition to the text, but am also grateful for the link to the article in the texts.

@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.

Seismic swarm hits Hayward Fault: What does it portend? - Temblor.net One may think that these quakes are small, so why do they matter? Why should I care?

Temblor article: temblor.net/earthquake-i...

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.

Agreed!!!! Yikes!!!

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

I think this is a perfect question for @dieworkwear.bsky.social

Here’s the recording of the M8.0 off Kamchatka from our @raspishake.bsky.social earthquake.usgs.gov/earthquakes/...

Woo! Felt that shaker! We’ll see how early I can follow asleep now. M3.4 Pinole earthquake!

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.

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. 🧪⚒️

A map of the contiguous 48 states titled: Thirty National Weather Service offices are without a chief meteorologist Some of these offices issue forecasts for major population centers such as New York City, Houston and Cleveland. Several are prone to hurricanes and tornadoes. Callouts include: Upton, NY - Covers New York City and southern Connecticut Tampa, FL - Hard hit by Hurricane Milton in 2024 Houston, TX - All management positions vacant Paducah/Louisville/Jackson, KY - Nearly the whole state of Kentucky is covered by forecast areas without leadership

Donald Trump and Elon Musk have left Houston, Tampa, New York and other major cities without head meteorologists just ahead of what will be another busy hurricane season

This is straight-up life-threatening malpractice

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.

This #poweroutage in the Berkeley Hills came just as we were starting to make dinner - extra terrible timing!

As a former Annapolitan, I recommend the Baltimore Aquarium if you have some time to walk around! Get there safely!

Ohh "America First" was a hit list

Map of Myanmar area showing sharp color change along the fault running roughly north-south. Red on west side where land moved northward.

NASA JPL ARIA project analysis of data from Copernicus Sentinel-2 optical and Sentinel-1 radar images measured the slip on the Sagaing Fault in Myanmar. Quick preliminary map. More details later. Fault ruptured about 500 km (300 miles) in the magnitude 7.7 […]

USGS map and diagram showing fatality probabilities and the area with extreme shaking and damage

USGS updated PAGER estimate. It's frightening. Zone of extreme damage is now shown elongated along Sagaing fault for >500km. 70% probability of fatalities > 10000 (~35% >100000). ⚒️ 🧪

These are probabilities, hopefully overestimated. In any case it's a massive disaster. Thoughts for the victims 💔

Map showing the segmentation of the Sagaing fault and the hypothetic historical ruptures

Today's #earthquake near Mandalay, Myanmar, had magnitude Mw 7.7 to 7.9.

Prelim. source models point to rupture duration & length of ~120s and at least 200km. It likely filled large part of seismic gap S of Sagaing (previous rupture in 1839) ⚒️ 🧪

Seismicity map with aftershocks as purple squares

Updated seismicity map for today’s M7.7 #earthquake in Myanmar: labeled earthquakes down to lower M (7.0) and included aftershocks located until now. Most early aftershocks appear to be located close to the mainshock epicenter. Also, apart from the one M6.4 aftershock, no M5+ (yet). 🧪⚒️

Staffing shortage puts office that forecasts weather for SFO in 'uncharted waters' The weather service unit, collocated within the FAA office in Fremont, provides forecasts for SFO, Oakland airport, San Jose airport and Hawaiian airports.

A Bay Area weather service unit that forecasts for SFO, all Hawaiian airports, California, Nevada and Pacific Ocean airspace is experiencing serious staffing shortages. The office currently employs just one meteorologist. Typically, four meteorologists work out of the FAA office in Fremont.
