Researchers use "thunderquakes" to study structure of Earth's surface

2+ hour, 37+ min ago   (872+ words) Ars Technica Most of what we know about the Earth’s interior comes from following seismic waves. These travel at somewhat different speeds depending on the details of the rock they’re moving through—whether it’s solid or semi-molten, how much water…...

The missing 500 million: Cosmic bombardment melted Earth's first crust

1+ mon, 2+ week ago   (340+ words) The heat of the Hadean may have come from impacts as well as the interior. Johnson and his colleagues are now arguing that the formation of continents on Earth was caused largely by an intense, sustained barrage of asteroid impacts…...

Feedbacks upon feedbacks: Rock weathering and the climate

1+ mon, 3+ week ago   (1076+ words) Rock weathering may release or draw down carbon dioxide—it depends on the rock. A new study in the journal Nature Communications uses the geological past to test how these competing effects added up. Doctor Madeleine Stow of the University…...

New paper argues history, not mantle plume, powers Yellowstone

4+ mon, 1+ week ago   (332+ words) A now-vanished plate under North America may open the crust below Yellowstone. Now, a new paper suggests that the Farallon plate is still making its presence felt far from the coasts, powering one of North America’s most distinctive phenomena: the…...

Perseverance’s radar revealed ancient subsurface river delta on Mars

5+ mon, 1+ day ago   (380+ words) There may be a river delta hidden under the obvious delta in a Martian crater. “I think it’s a promising place to look for signs of biosignatures at depth,” says Emily L. Cardarelli. “Microbial life could have potentially developed in…...

“Like putting on glasses for the first time”—how AI improves earthquake detection

10+ mon, 1+ week ago   (1673+ words) AI is “comically good” at detecting small earthquakes—here’s why that matters. On January 1, 2008, at 1:59 AM in Calipatria, California, an earthquake happened. You haven’t heard of this earthquake; even if you had been living in Calipatria, you wouldn’t have felt…...
