Earthquake Geologist in public service. Mostly tweets about earthquake geology and a cat..mostly. The “Earthquake Whisper who bakes bread and rocks out” per BlueskyRoast AI. Maybe a bit more Grateful Dead commentary than on the other site.

In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.
The Edmund Fitzgerald was the last.
The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.
Why?
It's NOAA. Of course it's NOAA.

This weekly roundup is a good reminder that earthquakes happen everyday in California. While most are small, eventually there will be one that will be disruptive and, knowing this, it is best to be prepared.
Between November 3 (12:00 AM PST) and November 9 (11:59 PM) there were 50 earthquakes in California of magnitude 2.0 or larger.
🔸45 quakes between magnitude 2.0 - 2.9
🔸5 quakes between magnitude 3.0 - 3.9
The largest earthquake was a magnitude 3.8 near San Ramon, CA.

Glad I took today off. It is 75 degrees and I’m in shorts and a tshirt. It is the San Francisco summer day I waited all summer and fall for.

The San Ramon earthquake cluster seems to be dying off, but this behavior could pick up again. There isn’t a way to say for sure what is next, which is why we focus on preparedness, rather than prediction. Hopefully this pattern continues and activity continues to diminish with time.

Quoted supporting our counterparts and friends at the Alaska Earthquake Center. The cost of the U.S. tsunami warning and mitigation effort is really a pittance. None of it has ever been adequately funded in any administration, and now things are worse. ⚒️ www.nbcnews.com/science/tsun...
U.S. tsunami warning system, reeling from funding and staffing cuts, is dealt another blow
Seismic monitoring stations in Alaska are closing after a denied federal grant, risking delayed tsunami warnings for people living on the West Coast.

I did not feel this or the M3.7 a bit later, but I was in the east bay working outside. A reminder that despite the federal government shutdown, a group of dedicated scientists at the USGS works to maintain networks that monitor earthquakes and other hazards. earthquake.usgs.gov/earthquakes/...

More than six years after the 2019 Ridgecrest earthquake, the surface rupture is looking very degraded south of the Spangler Hills, only well-preserved in select locations.

Civil liberties are under attack in the USA like never before. It’s scary, it’s real — and that’s why I hope to raise $100,000 this week to empower the American Civil Liberties Union (@aclu.org). But I’ll need your help.

I’m very impressed by the coverage of what should have been branded as the “Love America Protest”. Because, despite what Mike Johnson wants you to believe, everyone out there and millions more care about democracy and our country and want to push back those who embrace fascism.
