The USGS received more than 31,000 reports following yesterday's M4.3 #earthquake in Berkeley, California. The quake was followed by 7 aftershocks > M1, some of these may have been felt by residents near the epicenter. #DYFI 🧪⚒️ #Geology

Some of you might have felt light to moderate shaking near Berkeley, California following the M4.6 #earthquake just 5 mins ago. ⚒️ #Geology 🧪 Report here: earthquake.usgs.gov/earthquakes/...

Just deleted my science twitter and made a bsky... My feed was getting full of crazy stuff, and I pretty much just want to see things about rocks, earthquakes, and fluffy dogs/cats. Wassup?

Hey bluesky! I finally took the plunge. Posting links to the 2025 Santorini - Amorgos zone crisis as I figure this thing out 🌋

Today marks the anniversary of La Palma’s Cumbre Vieja eruption in 2021. Three years before the eruption I stood right at that very spot. By coincidence, I just booked our January trip to another Canary Island today - Tenerife! It will be great to be back. ⚒️🌋 youtu.be/EOIwjeJMNxM?...

Taking a look at Båth’s Law, which says the biggest aftershock is usually ~1.2 magnitudes smaller than the mainshock. For the M8.8 mainshock that's roughly M7.6 for the biggest expected aftershock - so this M7.8 aftershock is huge, yet still within the expected range. 🧪⚒️ #geology

⚒️ 🧪 Another big addition to the remarkable M8.8 earthquake sequence offshore Kamchatka: a M7.8 - the biggest aftershock so far. With foreshocks, aftershocks, aftershocks of foreshocks, and foreshocks of aftershocks, it's hard to keep these earthquakes straight! Read more about what's going on:

#Kamtchatka earthquakes sequences update. The activity remains concentrated to the north of the rupture zone.

A big #earthquake a few minutes ago at Kamchatka with a magnitude of M7.8! I guess this makes it the biggest aftershock following the M8.8 on Jul 30th. Here's the seismogram of my @raspishake.bsky.social - the seismic waves arrived about 11 mins after origin time here in Herne, Germany. 🧪⚒️ #geology

The USGS just released their ShakeMap for the M7.8 Kamchatka aftershock. Tsunami threat for Hawaii - 0.3 to 1 meters! A preliminary tsunami warning for Russian coasts within 1000 km of the epicenter has also been issued. #earthquake 🧪⚒️ #geology www.tsunami.gov

Big sigh. Watch this. Can you see why the Yankees’ moment of silence, the lowered flags, the promise of the Presidential Medal of Freedom, feel like a gut punch to the very people he spent years targeting? No one wished death on this man, but what we’re seeing right now is too f*cking much.

Here are some things that Charlie Kirk said in his life. The man is dead, and so it only seems fair to share his legacy by cataloguing the values he spread while alive.

Temblor's analysis of the July 2025 magnitude 8.8 Kamchatka quake explores some mysteries (a moderate tsunami, a curious eruption), and finds that the 10-day foreshock was exceptionally productive. temblor.net/earthquake-i...

There has been a small M2.2 #earthquake this early morning at 05:53 (02:53 UTC) in Gangelt, NRW, close to the Dutch border. Below you can find the seismogram of my @raspishake.bsky.social seismometer which is 100 km away from the epicenter. 🧪⚒️ #Erdbeben
