Good morning everyone. My 3D printed lidar-derived volcano tissue box covers are now for sale in my Etsy store. Majority are of Lawetlat'la (St Helens), Tahoma (Rainier), Wy'east (Hood), Kweq' Smanit (Baker), Kohm Yah-mah-nee (Lassen) and even one Salton Sea mud volcano. ⚒️ phaneritic.etsy.com

A new Temblor article talks about how Alaska's Connector Fault, which recently ruptured in the M7 earthquake on Dec. 6, was found and included in Alaska's seismic hazard map *before* the earthquake. ⚒️🧪

🌋⚒️📹💥

#AGU25 is coming up, and there's lots of neat research that'll be presented. I got to talk to some great scientists about work that pertains to sending people to the Moon and Mars for @eos.org! ⚒️🧪

As a long-time reader of @theopennotebook.bsky.social, I was happy to contribute to this article and be on the "other side" of the interview. Thank you @skylerdware.bsky.social for the opportunity. Lovely to hear how others are diversifying their work.

😮 Full disclosure, I have not read the paper yet. I've only read the abstract and scanned the figures. ⚒️

Double, double, toil and trouble... oh wait no. Bubbles, spatter, lava and tremor, there we go! For @earthscope.org, I dove into a paper that used drone footage from Geldingadalir's lava lake + seismic data to explore the source of volcanic tremor. ⚒️🧪 www.earthscope.org/news/bubbles...

Right on schedule! More than 10,000 tiny tremors (not felt) have rolled through #PugetSound and southern #VancouverIsland over the past 30 days. This is Episodic Tremor and Slip (ETS) and occurs here every 12-16 months: www.earthquakescanada.nrcan.gc.ca/pprs-pprp/pu... Also - it is #ShakeOut day! ⚒️🧪

Oxidised (left) and unoxidised 3.2 billion year old banded iron formation. These samples are from drill core and were only a couple of meters apart. #geology #paleontology

"we propose this Potassium-40 deficit represents primitive proto-Earth mantle domains that largely escaped mantle mixing after the [moon-forming] giant impact and exist in the present-day deep mantle, contributing to some modern hotspot volcanism" ⚒️ www.nature.com/articles/s41...

My latest for @earthscope.org combines Silurian reef systems with seismology! The highlighted research looks at how to parse noisy seismic data from a single station in the Chicago area. ⚒️🧪 www.earthscope.org/news/chicago...

Tomorrow is ShakeOut! On October 16 you can join geologists from the @cageosurvey.bsky.social at Tech Interactive in San Jose and in the California Natural Resources Agency Building as we talk about earthquake science and how to be earthquake ready.

I'm incredibly honored to be a part of this team and proud of this award!!! But I'm just a very small part of this program. Anita Marshall @bakingsodavolc.bsky.social deserves all the credit for the idea, the passion, the grunt work, and for its success!!! ⚒️🧪🔭

For @temblorinc.bsky.social, @beccapox.bsky.social writes about interesting new developments in tsunami early warning using prompt elastogravity waves, a small-amplitude, fast-moving seismic wave. ⚒️🧪

This earthquake was originally reported as a magnitude 4.6 but was downgraded to a magnitude 4.3. Remember, there is a trade off between speed and accuracy. As more data becomes available the initial reports are likely to be adjusted to reflect our improved understanding. Feature not bug.

What went well, and what needs to be improved when it comes to major earthquakes that shake Istanbul? In @temblorinc.bsky.social 's latest, experts explore aspects of a recent M6.2 earthquake that shook the city and reportedly caused panic. 🧪⚒️

How does insurance work when it comes to events like tsunamis? This short Temblor article describes one way path, built on NOAA's tsunami monitoring efforts. 10 days after the Kamchatka tsunami hit Samoa, the country received a payout from PCRIC. ⚒️🧪

Long but interesting! Check out @temblorinc.bsky.social's latest on the July 2025 Kamchatka earthquake, in which Temblor scientists look at stress transfer associated with 2 foreshocks. They also compare the mainshock to a similar 1952 quake, explore some tsunamis, and consider an eruption. ⚒️🧪

🔥PRESS RELEASE🔥Revisiting an Enigma on California’s North Coast: The Mw 6.5 Fickle Hill Earthquake of 21 December 1954 #BSSA What lies beneath Fickle Hill? The answer may help solve an earthquake mystery that has puzzled seismologists for decades. PAPER: pubs.geoscienceworld.org/ssa/bssa/art...

Finally got a chance to process some of my backpacking photos from Late July. I hope to share some pretty photos and general geoscience descriptions of the area in the coming weeks. For now, here’s a sunset reflection on a small pond next to Lower Golden Trout Lake in the John Muir Wilderness.

During a tsunami warning we always caution that a tsunami arrives as a series of waves and the first arrival is not always the largest. Larger tsunami arrivals can occur hours later. We can see this from the recent M 8.8 Kamchatka earthquake.🧪

I'll be on sabbatical starting January 1, 2026, and if anyone is looking for a guest speaker for department seminars, I'm happy to discuss possible dates. Reskeet widely! 🧪⚒️

Since people are still doing it and I'm going to have time to kill until I figure out what to for the rest of a chaotic week that promises to have lots of little pockets of down time: 1 like = 1 opinion about subducting slabs.

I am glad @evanbush.bsky.social used this quote in this excellent @nbcnews.com story. This is a key message I really wanted to get across in interviews today. Article here: www.nbcnews.com/science/scie...

the California Geological Survey has prepared a survey to gather your observations from the M8.8 Kamchatka, Russia Tsunami If you have been able to make any observations of the tsunami or of the evidence left behind by tsunami, we want your information: survey123.arcgis.com/share/76979d...

Great article with comments by @diegosismologo.bsky.social, @acarrerac.bsky.social, @seismo-steve.bsky.social and @judithgeology.bsky.social. Though the tsunamis weren't as massive as past events, people evacuated because of timely warnings and accurate forecasting of when/where waves would arrive.

Look at that hydrograph! This is from a USGS monitoring well in Christiansburg, Montgomery County, VA. Observation well 27F2 SOW 019 is 450' deep, completed in carbonate rocks of the Elbrook Formation and well known for its response to quakes. ⚒️🧪 Data: waterdata.usgs.gov/monitoring-l...

Per Tsunami.gov, the largest tsunami heights were: 5.7ft at Kahului, Maui 4.9ft at Hilo, HI 4.0’ at HALEIWA HI 3.7’ at Crescent City, CA. Complete list and wave periods are linked: www.tsunami.gov/events/PHEB/...

Temblor's map of the magnitude 8.8 Kamchatka earthquake has been posted. Wishing everyone in the Pacific coastal region a safe night on high ground as the tsunami waves come in. ⚒️🧪

The Earthquake Insights article about the Mw8.8 Kamchatka earthquake is, as always, really informative. ⚒️🧪 #geology open.substack.com/pub/earthqua...

Watch the seismic waves from the magnitude 8.8 earthquake off the coast of Russia sweep beneath seismic stations in North America. By the time the waves reached North America, they are far too small to be felt by people, but can still be detected by seismic instruments. 🧪

⚒️ 🧪 A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean. This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.

The magnitude 8.8 earthquake off Russia’s Kamchatka Peninsula is tied for the 6th largest ever recorded by modern instruments. Check out how the ground moved near you using our Station Monitor app ⬇️ https://loom.ly/LvUPs2g

Today's M8.8 (orange circle) and the 1952 M9.0 epicentral locations, separated by only 73 years. I wouldn't have thought that possible! Average recurrence intervals don't tell the full story. ⚒️

What governs whether the next big Cascadia earthquake will rupture the entire margin or stop partway? In our @weareseismica.bsky.social paper led by Jonatan Glehman, with Thomas Ulrich, Marlon Ramos, Yihe Huang, & Eric Lindsey, we link geodetic slip deficit models to 3D dynamic rupture simulations..
