There are all kinds of local elections coming up. Here in Tompkins County, early voting starts on October 25th, and election day is November 4th.

Support your local candidates with your wallet, and at the ballot box - they are working to get out the vote, and could use your help.

I'm running for something!

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.

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

In case you're wondering - I always kind of did - the money pays for literature (print-outs I can hand out when I go door-to-door) and yard signs. Visibility helps local voters stay tuned in, helping both the candidate and the party.

It turns out these things cost hundreds of dollars! Who knew?

Thanks! Right now I think I’m set - getting some great advice - but I might reach out later on, once the chaos is over, for advice on making effective policy.

To be clear, though, there are actually a lot of great geologists working on earthquakes in the Philippines. One problem is that the tectonics are so complicated. More importantly, knowing where faults are doesn’t actually make people safer - that requires more resilient infrastructure.

A M5.0 earthquake struck below the Sea of Marmara (Türkiye) yesterday, a little west of April's M6.2. Was this an aftershock? What does it mean for hazard? We have added a map and short discussion to our previous post, and removed the paywall. ⚒️ 🧪

A M6.9 earthquake struck Cebu island in the Philippines today, causing at least 20 deaths.

The rupture seems to have occurred on an unmapped fault, started below the ocean and continuing to the southwest, passing near populated areas of Cebu.

Northwestern Venezuela was struck by several large earthquakes today and yesterday (M6.2, 5.8, 6.3). Why did these shallow thrust events occur in an area where previously only strike-slip earthquakes have been documented? We speculate about the geology in our latest post.

⚒️ 🧪 Were you one of the tens of thousands in the Bay Area woken up by the M4.3 earthquake last night? The earthquake occurred on the Hayward Fault, which runs along the east side of the valley.

⚒️ 🧪 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:

PRI is very close to raising the funds they need, but must do so before the end of the year. A major donation or lots of small support could make the difference. PRI does a lot of good science, many researchers use their collections, and they are also a center of climate change & teacher education

A M7.4 earthquake struck Russia's Kamchatka peninsula today: the largest aftershock so far of the great M8.8 on July 29th.

What do we see in the seismic data so far? And what are the chances of a triggered earthquake next door?

I have just heard an ALARMING report that my former Department of Earth and Atmospheric Sciences at the University of Nebraska is threatened with elimination, due to a university & state-wide budget crisis, and despite their ongoing success in scholarship and teaching. This is really shocking.

The situation in Afghanistan is dire following the M6 earthquake on August 31st. More than 2,200 people have died; reports indicate that 65% of buildings in the region were destroyed.

Meanwhile, satellite imaging has begun to reveal both devastation and scientific details about the quake.

Great in-depth article about the M8.8 earthquake in Kamchatka - exploring all the fun questions, like:

What was it about the foreshock sequence that triggered the M8.8?
Why wasn't the tsunami bigger?
Did the earthquake trigger an eruption?

Answers are hard, but the science process is fun.
