Seismologist who joined the Great Resignation in academia & moved from CA to Italy. Still figuring out what’s next, but enjoying the process.

Within a few weeks we switched from peak fall colors to what feels like deep winter!

Some coverage from the BBC on our Santorini swarm paper in Science (www.science.org/doi/full/10....). Features an interactive slider graphic showing the imaged magma dike intrusion using @alomaxnet.bsky.social's Coulomb-based seismicity-stress (CoulSeS) method.

The volcano near Naples is shaking the ground in a way that scientists say it hasn't for centuries, posing risks for hundreds of thousands of people living in the 8-mile-wide crater left by past eruptions. n.pr/44w8Kox
Italy's Campi Flegrei supervolcano is stirring. Could this seismic giant soon erupt?

Most if not all geophysics faculty at the R1 where I went to grad school would become ineligible for future federal funding if this ban passes congress. 🧪⚒️
environmicrobio.bsky.social Roland Hatzenpichler @environmicrobio.bsky.social · 13d
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

NOAA cut funding for critical parts of the tsunami and earthquake detection system in Alaska, primarily in the Aleutians. I spoke to Wash Post about negative impacts. But, hey, what are the chances of a deadly tsunami being triggered in Alaska? (Gift article, not behind paywall) ⚒️ wapo.st/4qKvavQ
This lab is key for tracking deadly waves. Its sensors are about to go offline.
After NOAA cut funding to the lab that’s been monitoring seismic activity for more than 25 years, nine stations tracking tsunami-causing earthquakes for the agency will go offline by the end of the mo...

I generated a quick map for the current earthquake sequence near Japan, in a complex area of the subduction zone (or maybe it’s only considered complex because it is so well instrumented…) ⚒️

I realize this is turning into a fall colors account, but I’m still pretty excited about experiencing real seasons, so here is one more! 🍁🍂

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

Fellow seismologists, we're going to get a lot of mileage out of the latest @xkcd.com
xckd coming of a flowchart. The top reads "someone is claiming to predict the exact date of a future earthquake. Should you listen?" A diamond-shape says "start" and one arrow leads to a box reading "NO" in very large letters, followed by "(there are big earthquakes constantly, so if anyone ever DOES figure this out, it will be immediately obvious that their method works and then the world's seismologists will not shut up about it. You won't need this flowchart."

I get notices for homes on Cape Cod that are like "$20,000 price cut! Imagine waking up to the sunrise every morning!!"

Yeah, imagine waking up in the Atlantic Ocean one morning.

NEW: The Trump admin just ended the practice of automatically extending work permits when people file to renew them — meaning that if USCIS takes too long to process a renewal the applicant loses their authorization to work legally.

The interim final rule applies to renewals filed after tomorrow.
This document is scheduled to be published in the Federal Register on 10/30/2025 and available online at https://federalregister.gov/d/2025-19702, and on https://govinfo.gov DEPARTMENT OF HOMELAND SECURITY: Removal of the Automatic Extension of Employment Authorization Documents AGENCY: U.S. Citizenship and Immigration Services (USCIS), Department of Homeland Security (DHS). ACTION: Interim final rule (“IFR”) with request for comments. ______________________________________________________________________ SUMMARY: This IFR amends DHS regulations to end the practice of automatically extending the validity of employment authorization documents (Forms I-766 or EADs) for aliens who have timely filed an application to renew their EAD in certain employment authorization categories. The purpose of this change is to prioritize the proper vetting and screening of aliens before granting a new period of employment authorization and/or a new EAD. This IFR does not impact the validity of EADs that were automatically extended prior to [INSERT DATE OF PUBLICATION IN THE FEDERAL REGISTER] or which are otherwise automatically extended by law or Federal Register notice.

Not good for #jamaica. #Melissa may be the strongest hurricane to ever hit the island. 3 feet of rainfall totals = catastrophic flooding with years of recovery. This storm is moving slower than we walk.
