Small symbols of support mean SO much.

So we fly a pride flag in our front yard in a very conservative neighborhood and it’s been there for the last few years. Someone put this in our mailbox and my goodness…

This will never stop blowing my mind. A 12-year sequence of real telescope images of a star 133 lightyears away. And around it, four planets slowly orbiting. Four real exoplanets, each more massive than Jupiter, imaged as they move around their host star.

Desperately trying to balance two things: (1) my anger at people who hate gay and trans people but allege to love Dolly Parton, and (2) my desire to be more like Dolly and not be judgy and hateful towards the people in category (1). Failing so far.

Dreadful scenes from the devastating Rasuwa flood in Nepal/Tibet. My heart goes out to everyone affected. It likely began with a glacier collapse / rock–ice avalanche recorded by seismometers worldwide. I hope real-time seismic monitoring can support early warning for communities downstream.

I appreciate that Dolly Parton refused to participate in "dress respectability" and, by her own account, modeled her aesthetic after a town "tramp," who she thought was beautiful. She separated aesthetics from character and understood "classiness" to be about how you treat people, not how you dress.

Three more days to comment on NSF's attempt to smuggle in OMB's already-rejected policies of terminating any grant without cause, gutting civil rights obligations and restricting international collaborations. Submit your comment today! Then call your representatives. 🧪

My comment on NSF-2026-OTR-0001, NSF's obsequious gutting of their own procedures, replacing them with OMB's proposed rules undermining federal grantmaking with their ideological agenda. Need guidance on commenting? @standupforscience.net has you covered: fight2win.standupforscience.net #NSF

Late notice, but if you're interested in last year's Tracy Arm landslide and tsunami and the potential use of seismic data to forecast such events, I'm giving a Zoom talk today on that topic. Thanks to the National Disaster Preparedness Training Center for the invitation to present!

#USMNT got supporters rockin'n'rollin' in Seattle Stadium! Even with the flag up, Freeman's header tops the list and fans went WILD after the VAR overturn! Here's how Seattle #FIFAWorldCup goals stack up so far. Stay tuned to see how next other matches stack up to the USA goals!

Literally weeping this basic shit is what governance was always supposed to be and we have become so used to corporate corruption and theft that the most basic concept of "making people do the things they are legally obligated to do" seems revolutionary

Johnson: if you don't offer a competitive salary you won't get the best candidates to run for congress. Cool. Now do teachers.

Mickey Kuhns@mickeykuhns.bsky.social

Speaker Mike Johnson argues Congress should get to keep engaging in insider trading because they don’t make enough to feed their families. The average net worth of a Congress member is $8 million, which is 116 times that of the average American. You don’t hate Congress enough.

The kids are alright.

2026 spell the professor's name correctly on the final paper challenge

This is why I have so enjoyed working with the team studying the Tracy Arm. I've gotten to engage with geomorphologists, tsunami scientists, other seismologists, climate scientists and many others. I've learned a ton from them. Collaborative science, for the win!

I think this speaks to the dangers of scientific silos. If I write my science to an audience that does the same thing as me, I may be missing an opportunity to connect with others who can correct me, modify my ideas, or extend them into other domains. That's a critical part of the process.

My papers all suggest that this is an ice phenomenon. I published in the Journal of Glaciology and I had words like "ice avalanche" in the titles. It's likely that people studying failures in rock would never have seen the papers.

There are other scientists who got it right, but their papers are more recent. Yamada et al. (2016) describe a precursory seismic sequence before a landslide in Japan, and Poli (2017) and Butler (2019) describe precursors to the 2017 Karrat fjord failure.

The first time this type of precursory signal was observed was during a glacial avalanche on Mount Baker volcano (credit to Weaver and Malone, 1977). I wrote a number of papers about similar events on Iliamna Volcano: ice avalanches that stuttered and skidded before collapsing.

These slides all had one thing in common: they were made of ice. As a consequence, we thought that it was the presence of ice that made the precursory signals possible. I thought that rock would behave differently.

If you read our paper you'll learn that the landslide was preceded by days of tiny earthquakes--a precursory seismic sequence that was only detected in retrospect. When Jeffrey and Christine asked me to check the seismic data, it was that sequence that told me that there had been a landslide.

How did I know this was indicative of a slide? Well, of all strange coincidences, I've been studying that exact precursory signal for about 20 years. Yep. My friends know one seismologist and it happens to be a person who studies the exact signal that we saw in the Tracy Arm data.

Can we take a moment to recognize how cool this is? My friends are not geologists but they are (a) extremely familiar with the geology of Alaska, having run cruises there for 20+ years, and (b) knew the wave was anomalous.

I first learned about the landslide and tsunami about an hour after it happened, when my friends aboard the M/V David B (see map above) observed a surge of water entering the cove where they were anchored. They messaged me and asked me to check the seismic data to see if a landslide had occurred.
