Cascadia is so weird! Kidding, it's actually fascinating. Diving into what might be happening near and just south of the Mendocino Triple Junction was deeply satisfying for someone who studied Cali's accretionary prisms long ago (that someone is me, btw). Check out my latest, for @earthscope.org! ⚒️🧪

The tectonic plate boundaries off Northern California are complex. Recent research suggests it might be even weirder than it looks on the surface, with a piece of the old Farallon plate stuck to the Pacific plate beneath California. Read more ➡️ https://loom.ly/_zeAgvg

The Cotabato Trench, and perhaps the southernmost Mindanao Fault, may be closer to failure as a result of the magnitude 7.8 mainshock in the Philippines, according to Temblor scientists Ross Stein and Shinji Toda. ⚒️

Temblor's latest, by Ross Stein and Shinji Toda, considers what happened in the southern Philippines as a result of the recent magnitude 7.8 earthquake, and where future megathrust quakes might strike. temblor.net/earthquake-i...

So fun to write about seismology+Columbia Glacier for @earthscope.org! Bonus: I got to talk to one of my fave glaciologists, Kurt Cuffey @ucberkeleyofficial.bsky.social! New research from @uafairbanks.bsky.social connects glacial quakes how Columbia loses ice at its terminus. ⚒️❄️

EarthScope Consortium@earthscope.org · 2mo ago

As Alaska's Columbia Glacier launches icebergs into the sea, seismometers record the action of the ice crashing into the water. Looking at the data over time, you can see how the glacier is retreating. Read about the research ➡️ https://loom.ly/Ti_p0jU

Every so often when I'm interviewing a scientist, they explain something to me in such a clear and illuminating way that I have an internal epiphany. When I put on my science writer hat, my goal is to pass those epiphanies on to y'all ❤️

My latest, for @eos.org! Yes, its about a way to narrow the search for certain critical mineral deposits. But consider this: The paper uses GPlates, built on paleomagnetic data, geochronology, and geodynamics. The lead author studies petrology and geochemistry. Such work needs all of geology ⚒️🧪

Eos@eos.org · 2mo ago

Scientists present a compelling correlation between carbonatites—often host to critical mineral deposits—and sections of Earth’s continents that sit near zones of past subduction. Story by @dralkatrip.bsky.social. eos.org/articles/anc...

This article in @temblorinc.bsky.social talks about how swarms along the Cotabato Trench in the Philippines are reminding us that the trench remains a potentially hazardous plate boundary, even though the quakes may not be a preface to a repeat of a major 1976 event. ⚒️

Temblor, Inc.@temblorinc.bsky.social · 3mo ago

In Temblor's latest, DOST-PHIVOLCS scientists explore recent earthquake swarms off the shores of the southern Philippine island of Mindanao, and compare what's happening to the devastating 1976 Moro Gulf earthquake. temblor.net/earthquake-i...

80 years ago today, Canadian-born physicist Louis Slotin, 35, received a lethal dose of radiation at Los Alamos Laboratory while performing a very dangerous criticality experiment known as “tickling the dragon’s tail” with a plutonium bomb core. He died from acute radiation syndrome nine days later.

Louis Slotin's official Los Alamos ID badge photograph, showing a man with short, dark hair, a broad nose, and eyeglasses.A black and white photograph of a re-creation of the experimental setup Slotin was using, showing a man from the waist down standing behind a laboratory table holding a beryllium hemisphere above a plutonium core with his left hand (at upper thigh height) and a screwdriver in his right hand (as if preparing to use the screwdriver to raise and lower the beryllium to take measurements).A black and white diagram showing the locations of Slotin and everyone in the room with him, and their distances from the bomb core on the table. The two people closest to the core were Louis Slotin (1.5 feet) and Alvin Graves (3 feet).A color photograph of Louis Slotin's hands, lower arms, and upper torso, taken as he lay in a hospital bed not long after the accident. His left hand looks somewhat swollen and cyanotic and his right fingers appear swollen. There are small, dark marks on two of his fingers, possibly blood blisters.

I was given the excellent advice to read about my dissertation field in chronological order when possible so I have a better understanding of how current thought developed

Tressie McMillan Cottom@tressiemcphd.bsky.social · 3mo ago

I sincerely got to graduate school and almost immediately locked myself in the library. All I wanted to do was read. I’m still mad at how hard it is to find time to read! This isn’t nearly as common as I naively imagined when I started out.

⚠️Earthquake preparedness saves lives⚠️ Thats why AGU joined science partners urging the House to pass NEHRP reauthorization. Learn more and share with others👇 thebridge.agu.org/2026/05/04/a...

AGU Joins Letter Urging Passage of NEHRP

On 16 April 2026, AGU joined other science societies in a letter to the House urging passage of the National Earthquake Hazards Reduction Program (NEHRP) Reauthorization Act of 2025.

Hey folks! If you happen to be building seminar/colloquia series and you want someone who can talk volcanoes and magmatic systems, ping me! I have highly technical stuff on zircon geochronology as well as high accessible stuff like how to figure out the most dangerous volcano on the planet.

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. ⚒️🧪

Temblor, Inc.@temblorinc.bsky.social · 4mo ago

Saturday marked the 120th anniversary of the great 1906 San Francisco earthquake. Temblor CEO Ross Stein read a passage from Jack London's story of the quake over a montage put together by @kpixtv.bsky.social reporter Brian Hackney. www.youtube.com/watch?v=mUnE...

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. 🧪⚒️ www.earthscope.org/news/what-li...

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 ⚒️

Shiv Ramdas Mens Rice Activist@nameshiv.bsky.social · 4mo ago

one of the hardest science topics is explaining to a modern person that in the 1800s geologists were more popular than streamers are today books exploring topics like the history of a rock were doing multimillion print runs, & guys giving talks on igneous vs metamorphic were filling sports stadiums

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? ⚒️🧪 www.earthscope.org/news/new-jer...

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/

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. ⚒️

Temblor, Inc.@temblorinc.bsky.social · 4mo ago

What would happen to global markets should a major earthquake strike Tokyo? A 2022 report considers this question. The answer? It depends. Find out more, in Temblor's latest. temblor.net/earthquake-i...
