It’s #earthscienceweek so I thought I’d go into a bit more detail on how educators can use to our Quick Quake tool to demonstrate how @earthquakes.au seismologists quickly calculate the location and magnitude of an earthquake. It works on macOS machines with Apple Silicon too.

It was a pleasure to contribute to this article, which talks about how AI contributes to seismology - indeed, we have seen tremendous progress in the use of machine learning to detect small events.

AI is “comically good” at detecting small earthquakes—here’s why that matters.

Anticline in the Paleoproterozoic Thomson Formation, near Jay Cooke State Park, Northeast #Minnesota. Deformation due to the Penokean Orogeny, ca 1850–1900 Ma. This is a favorite fieldtrip stop; included in the GSA Centennial Guidebook. An October picture from the archives. #geology #FridayFold 🧪⚒️
Outcrop along a riverbank showing a gray fine grained rock. Bedding planes dip in opposite directions on either side. Part of a bridge can be seen crossing the river. Satellite image with the location of the outcrop shown. The St. Louis River has continuous exposure of the Thomson Fm towards the ESE. Town of Carlton to the west.

⚒️🧪 Fiery eruption of Otman-Bozdagh mud volcano in Azerbaijan!

The Otman-Bozdagh mud volcano erupted at ~8:27am local time today (11/10/25).

Three eruption phases of between 4-12 minutes were recorded over an ~40 minute period.

🦥 #FossilFriday P68.40.1 - the rarest Minnesota fossil I’ve ever held in my hand: an ungual phalanx of #Megalonyxjeffersoni (Giant #GroundSloth). Discovered in a pile of excavated peat, this individual toe claw remains the singular specimen of this animal found in the state.

Discovered in the late 1960s by a City of Minneapolis Park Board Department worker in a pile of excavated peat, this individual toe claw remains the singular specimen of this animal found in the state and is now in the Science Museum of Minnesota’s collection.

Telmatomyia means “fly from standing water.”
It’s the oldest record of non-biting midges from the Southern Hemisphere — from the famous Talbragar Fish Bed, a fossil snapshot of life in a lake that covered parts of New South Wales ~150 million years ago.

What percentage of the benefits of scientific conferences do you think comes from sharing our work with each other vs simply having a deadline we are forced to finish things by? Could be 50/50
