The Frequency of Asteroid Impacts Jumped Just Before the Dinosaur Age, New Research Suggests  

By comparing the age of impact craters on the Moon to those on Earth, researchers say they have discovered a surge in the rate of asteroid strikes starting around 290 million years ago—a finding that runs contrary to scientific convention. And indeed, not everyone is convinced by the evidence. Read More >>

Two Stalagmites Found in Chinese Cave Are a ‘Holy Grail’ for Accurate Radiocarbon Dating

Since its inception in the 1950s, radiocarbon dating has proven indispensable to archaeologists and climate scientists, who rely on the technique to accurately date organic compounds. But a good thing just got better, owing to the discovery of two stalagmites in a Chinese cave containing a seamless chronological atmospheric record dating back to the last Ice Age. Read More >>

Geologists Joke About ‘Sea Monster’ After Mysterious 30-Minute Rumble Emanates from Waters Near Madagascar

Between Mozambique and Madagascar lies the island of Mayotte. Since May 10, the French Geological Survey has been keeping an eye on a collection of earthquakes taking place just off the island’s eastern shores, which peaked with a magnitude 5.8 shake. This swarm was curious enough all by itself — and then, on November 11, things took a peculiar turn. Read More >>

‘Dormant’ Supervolcano Packed With 240 Cubic Miles of Magma

It’s been around 100,000 years since the Long Valley supervolcano in the US state of California experienced a major eruption, but this supposedly dormant caldera has been acting a bit strangely over the past four decades. New research suggests 240 cubic miles of magma still exists within this supervolcano, but thankfully, a major eruption remains unlikely. Read More >>
