An artificial-intelligence approach borrowed from natural-language processing — much like language translation and autofill for text on your smart phone — can predict future fault friction and the next failure time with high resolution in laboratory earthquakes,. The technique, applying AI to the fault’s acoustic signals, advances previous work and goes beyond by predicting aspects of the future state of the fault’s physical system.
Scientists seeking the connection between gravitational forces deep in the Earth and landscape evolution discovered that deep roots under mountain belts trigger dramatic movements along faults that result in collapse of the mountain belt and exposure of rocks that were once below the surface.
Some estimates of Antarctica’s total contribution to sea-level rise may be over- or underestimated, after researchers detected a previously unknown source of ice loss variability.
Deep valleys buried under the seafloor of the North Sea record how the ancient ice sheets that used to cover the UK and Europe expelled water to stop themselves from collapsing.
When the Chelyabinsk fireball exploded across Russian skies in 2013, it littered Earth with a relatively uncommon type of meteorite. What makes the Chelyabinsk meteorites and others like them special is their dark veins, created by a process called shock darkening.
ST. LOUIS – A $1 million grant from the National Science Foundation will create the Taylor Geospatial Institute Regional AI Learning System. Launched in April 2022 and led by Saint Louis University, the Taylor Geospatial Institute brings together eight Midwestern universities and research centers to harness innovation in geospatial science.

Pittsburgh’s steel industry may be largely in the past, but its legacy lives on in city soils. New research led by Pitt geologists shows how historical coking and smelting dropped toxic metals in Pittsburgh’s soil, particularly in the eastern half of the city. With samples from 56 parks, cemeteries and other sites around the city collected by Carnegie Mellon University students and Jonathan Burgess from the Allegheny County Conservation District, the team was able to pinpoint some of those polluting factors. They recently published their results in the journal Environmental Research Communications.
