Apparently surface rupture during the Myanmar 2025. I'm very surprised by the weak shaking along the rupture. I'm not sure if this is the main rupture (I would say no - nonetheless, VERY COOL). Author unknown, location Thazi (to be confirmed)

New satellite imaging of the Myanmar earthquake area confirms that the rupture was unusually long: ~500 km.
We discuss the data, the rupture, and the implications, in our latest post.

Impressive rupture 👇 for 28/03 #Myanmar #earthquake. Straight, simple. ⚒️ 🧪
It extends far to the south, much further than initially thought. Suggests that large part of segment broken in 1930 (Pyu quake) broke again. In addition to 1839 one of course.
Congrats @zaxonlee.bsky.social for this work

Two days after the M7.7 earthquake in Myanmar, what have we learned?
Rapid seismological analyses shared by scientists suggest that the rupture was both longer and faster than expected - two factors that could have increased damage.

This is an excellent post, summarizing the scientific data from the Myanmar earthquake. The long fault and close proximity to major cities indicate a high level of damage and we should expect the death toll to rise. But the ongoing civil war near Mandalay suggests we may never know.

People have been talking a lot today about it being the fifth anniversary of the first #covid #lockdown in the UK. Weirdly, it feels like it was both yesterday and ages ago.
Hearing about people's memories made me think of how incredibly different my own experience was, at least in the beginning.

A M7.3 earthquake recently struck the island nation of Vanuatu, causing significant damage: collapsed buildings, crushed cars, landslides, and a small tsunami. The UN reports that at least six people have been killed.
Why did this earthquake occur, and what made it so damaging?

Earthquake Q&A thread 🧵
Q1: Why didn’t this earthquake generate a tsunami?
A1: This earthquake moved the ground sideways. Underwater quakes where the ground moves up are the ones that usually generate tsunamis. This video explains.

At this spot, three tectonic plates come together, and since they're all moving in different directions and at different speeds, there's a lot of activity. This area has M6+ earthquakes more often than anywhere else in California.

The Triple Junction is the most seismically active part of California. Three M6+ earthquakes here since 2021 (2021, 2022, 2024)—all in December. This event appears to be farther offshore, and we will need to wait and see aftershock patterns and ground motions to get a better sense of the event.
