A M5.5 earthquake killed at least ten people in Bangladesh today. What made this moderate event so deadly? And what do we know about seismic hazards in the country?

Earthquake Insights is making *almost* $20k a year - which is simultaneously more than I ever thought it would make, and not nearly enough to raise a family.

Throwback to International Geophysical Year, 1957-1958, when WHOI leased the USCG cutter Yamacraw for acoustic studies of the N. Atlantic & Mediterranean.
After the last logs were recorded, scientists & crew gathered below deck for a jam session. Let's hope the banjo didn't influence their data!

The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

A M6.8 earthquake struck offshore Japan today - another large earthquake from the subduction zone that produced two recent great earthquakes. The earthquake was preceded by a "cascade up": foreshocks progressively increasing in maximum magnitude.
What do we know? What might happen next?

A M5.7 earthquake shook the island of Cebu in the Philippines today - an aftershock of the deadly M6.9 on September 30th.
Although the mainshock was strike-slip, this aftershock was a thrust - consistent with mapping of this newly discovered fault based on field studies and satellite imagery.

October 10th was marked by two M7+ earthquakes on the same day - 14,000 km apart! How unusual is that? We crunch some numbers.
Also: what’s going on in the Drake Passage? 2025 has seen three mid-M7 earthquakes there, after decades of relative seismic silence. What can the limited data tell us?

It was a pleasure to contribute to this article, which talks about how AI contributes to seismology - indeed, we have seen tremendous progress in the use of machine learning to detect small events.

M7.4 just struck the coast of the #Philippines at a depth of 58.1km according to the USGS.
The #earthquake shown occurred on the western margin of the Philippine Trench, where the Philippine oceanic plate begins its subduction beneath the Mindanao microplate.

The world is a complicated and increasingly scary place. Decisions made at the local level will have real impacts. That's why I'm running for a seat on the Tompkins County Legislature.
If you can afford to pitch in, I'd really appreciate your support.
