A new paper by @tellurianite.bsky.social reveals reduced velocities in the lower crust beneath major volcanos in the Aleutian Arc, which may reflect elevated temperatures and/or siliceous crust in the making. Check it out! @nau-ses.bsky.social @lamont.columbia.edu @whoi.edu eos.org/editor-highl...

A Snapshot of Continental Crust in the Making - Eos

New seismic images from the Aleutian Arc show how active volcanic arcs may build new continental crust, highlighting the complex transition at multiple stages.

New article in Science by the #JTRACK science team, led by Jamie Kirkpatrick, on extreme localization of the plate boundary megathrust fault at the Japan Trench: www.science.org/doi/10.1126/... ⚒️

Extreme plate boundary localization promotes shallow earthquake slip at the Japan Trench

The 2011 Mw9.1 Tohoku-oki earthquake is exceptional among great earthquakes for having peak slip of ~50-70 m on the shallowest portion of the plate boundary megathrust. Drill cores and geophysical log...

Many congratulations to Patrick Chindandali, who successfully defended his MS last week and deposited the final version of his excellent thesis today! Congrats, Patrick!!!

Our Introduction to Oceanography class took a 5-day field trip to The Ocean, visiting some spectacular spots near Big Sur and Monterey. Some major storm systems battered the coast while we were there, so the weather was.... epic. But so was the geology, biology and oceanography 🙂.

A couple of SES undergrad and grad classes have recently ventured to the San Juan Mountains in Colorado to learn about fundamental geological processes that have shaped this spectacular range. The fall foliage wasn't bad either :)

Fun afternoon of science on Saturday at the NAU open house in the Flagstaff Festival of Science! SES students and faculty showcased everything from volcanos and earthquakes to insects. Thanks to our amazing students for sharing their knowledge and to everyone who stopped by!

Many congratulations to SES Prof @rengellia.bsky.social , who was awarded the prestigious @agu.org Asahiko Taira International Scientific Ocean Drilling Research Prize! www.agu.org/honors/taira

NAU SES scientists just finished 11 glorious days of lake coring and glacial geologic mapping around Turquoise Lake in Lake Clark National Park, western Alaska Range. Good weather, hard work, and epic landscapes => an unforgettable field season. #NAU_geology, #NAU_environsci, #NAU_climate

Myself, @kdmorell.bsky.social, @djshillington.bsky.social, and Rob Witter (USGS) used an SSA community grant to host an Alaska Subduction Zone workshop in conjunction with a USGS meeting in January. The community grants are a great option if you're looking to fund a workshop/training. ⚒️
