Such a hard question to answer. Arizona geology is spectacular. One place I can't wait to take my kids to is SP crater, mentioned in the article. But also, I do love the ancient dunes, like the Navajo sandstone that you can see in fantastical fashion if you go to Antelope Canyon.
Check out this news segment featuring @temblorinc.bsky.social CEO Ross Stein talking about the 1906 San Francisco earthquake! The photos over which he narrates Jack London's reporting are heartbreaking. ⚒️🧪
To quote Steve Semken of @seseasu.bsky.social, who led me (and many students) to see some incredible rocks here, "I LOVE ARIZONA GEOLOGY!!!"

More good stuff for @earthscope.org! This feature dives into a @geosociety.bsky.social paper about Arizona's San Francisco volcanic field, a sea of monogenetic (single-eruption) vents in the northern part of the state crowned by a curious stratovolcano. 🧪⚒️

Love the book Dinosaurs at the Dinner Party by Edward Dolnick, in which Dolnick tells the stories of some of the geo-celebs of the 1800s ⚒️
I had good fun diving into this @seismosocam.bsky.social paper for @earthscope.org on the topic of how an earthquake in New Jersey drove research into 3D seismic velocity models. Also discussed: What is even a seismic velocity model and why should anyone care? ⚒️🧪

Did you hear or feel the sonic boom from the Artemis II reentry? Fill out a “Did You Feel It?” report!
It will say earthquake but fill it out for the boom.

See that planet in the distance? That’s us. ALL of us. Every living being we are aware of lives there. We are completely alone, floating in the great abyss of dark, infinite space. Life like ours is incredibly rare - perhaps even without precedent - in the Universe. All we have is each other… 1/
Did you feel last night’s M4.6 earthquake in the Bay Area? If so, you’re not alone: more than 32,000 people have reported it so far. We explore the geology to try to figure out what fault ruptured, and what to expect.

A sketch of a tall, thin tree with a cloudy puff at the top and two little branches just below. Otherwise, it is mostly a long tree trunk. The height of the tree is labeled L (m) and the diameter is labeled D (m). From Hough, 2026, published in The Seismic Record.
As usual, @seismosue.bsky.social brings the best article titles: Only Very Strong Shaking Can Break a Tree.
And the figure of the tall tree 😂

When we think about the aftermath of major earthquakes, we often first (and rightly) begin with the population. But another consideration is how such an event's effects might impact the regional and global economy. Take Tokyo, for example, in Lauren Koenig's latest for TEN. ⚒️
US GEO folks: A few NSF POs are traveling again (!!) & several are hitting the regional GSAs. @drrocks1982.bsky.social + @llautz.bsky.social are headed to the Triple-Joint meeting in Memphis, I'll be in Hartford for the Northeastern. We are hype to see the community! Reach out if you'll be there!
Coulomb 4.0 is here, via @temblorinc.bsky.social! What's this, you ask? It's the latest version of an open-source Matlab program that can help you visualize how stress is transferred when faults rupture. Find out more in this article by the scientists that developed and refined it! ⚒️
I'm constantly trying (/failing) to get this point across.
If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.
If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.
What happens when you consider #earthquakes as a social phenomenon? Learn more in this month's SSA At Work with Max Schneider! buff.ly/RCVMm4P ⚒️
Let me just make a few little adjustments to that title…
“How a scientist with a PhD in Geology and 25 years of experience is helping lead California’s earthquake work”
Way to devalue my experience.
📣PRESS RELEASE📣 Rupture into Slow‐Slip Fault Regime During the 2018 Mw 6.9 Island of Hawai‘i Earthquake is Followed by Modest Postseismic Slip #BSSA ⚒️
A M6.9 Hawaii quake may have stalled episodes of periodic slow slip.

Maureen Long at a talk hosted last October by Yale's St. Thomas More Chapel on her work, the role of Catholicism in her intellectual life, and coexistence between faith and science. Taken from the St. Thomas More Chapel Instagram account (most recent photo I could find).
Ok, positive scientific thing (for a change):
We're going to talk about the work of Yale seismologist Maureen Long, because her work is focused on the most direct evidence of mantle flow and convection we can get.
Her career essentially defines our direct knowledge of mantle flow.
For @highcountrynews.org's latest issue on Deep Time, I reviewed 3 books that help us explore Earth's past in different ways: Basin and Range by John McPhee, Strata by @laurapoppick.bsky.social, and When the Earth was Green by @restingdinoface.bsky.social 🧪⚒️

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. ⚒️

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. ⚒️🧪

Map of the Puget Sound and Vancouver Island region showing the location of tiny ETS tremors (not earthquakes and not felt) from September 15 - October 15. Locations are colour-coded by time.
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:

"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" ⚒️
