20 minutes ago, very deep (600 km) Mw7.1 earthquake below Sabah, Malaysia.
Deep enough to be harmless, I suppose, but (due to the depth) were felt at great distances
This type of events are relatively common more to the east, at Celebes Sea, not here...

Signal on seismic station AU.FITZ from a Malaysian earthquake February 22, 2026.

Magnitude 7.1 #earthquake just over an hour ago off the coast of #Malaysia (2026-02-22Z16:57) The good news is that it is deep (over 600 km) which greatly reduces the harm it can cause.

Research shows that ChatGPT is changing your brain People worry that students are increasingly using generative AI in their work. It saves time, but what is it doing to their brains?

What happens to your brain when you use ChatGPT to write your essay? MIT watched students’ brain activity to find out. The results are worrying.

Experienced an earthquake a few minutes ago. Aftershocks are still coming, some strong and some are alright but felt.

Apparently the epicenter is around mag. 7 and our region is feeling around mag. 5 πŸ₯²

Trailblazers: Chemists with disabilities rethink how we do science C&EN’s 2025 Trailblazers issue, curated by guest editor Mona Minkara, looks at how chemists can solve problems in new ways

It so was hard to imagine having successful career in science as a disabled PhD student that eventually I just left.

Who could have guessed that years later I would help create a magazine issue dedicated to highlighting Trailblazing disabled chemists!

Deadly M6 earthquake strikes northeastern Afghanistan Shallow thrust faulting in a highly vulnerable region

βš’οΈ πŸ§ͺ

A magnitude 6 earthquake struck northeastern Afghanistan just before midnight on August 31st. Vulnerable homes built of mud, brick, stone, and wood collapsed; the reported death toll has exceeded 800 people.

Why do earthquakes occur here, what happened in this one, and why was it so deadly?
