Understanding earthquake magnitude is simple. I don’t know why everyone is so confused 🤪

This may just be my favorite video from Thursday's shaker. Whatever happened to animals being able to sense an earthquake coming? These birds are basically unruffled. Maybe they're used to it? Thanks to Michele from Knik for this one! And to everyone who shared your informative videos.

This morning, a M6 earthquake struck at ~70 km depth near Anchorage, Alaska.
Earthquakes are a regular part of life here: this is a subduction zone, with earthquakes deepening east to west. M6 earthquakes fall well within the range of "normal".

What should you do to prepare for earthquakes in Bangladesh — especially if you don’t live there anymore?
I had the pleasure of chatting with Anil Wasif from BacharLorai Global, a nonprofit aimed at empowering Bangladeshis worldwide, about the recent quake, seismic hazards, and how to do better.

Some footage from Bangladesh, post M5.5 earthquake. This is probably lateral spreading and slumping associated with earthquake-triggered liquefaction. Liquefaction is a huge hazard in Bangladesh, because so many people live in low-lying areas on saturated sediments.

Hopefully, if this does come to pass, any new construction will take seismic risk into consideration. Tehran is an earthquake disaster waiting to happen. Retrofitting old buildings is much harder than building new ones that are more resilient.

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!

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?
