While analyzing strong-motion data close to fault lines, a group of researchers at Kyoto University noticed something unexpected: a negative phase in the waveforms, a pattern that did not conform to ...

In a new study published in Scientific Reports, researchers at University of Tsukuba analyzed seismic waveform data from a tsunami earthquake (moment magnitude Mw 8.3–8.5) that occurred on August 12, ...

On Monday residents of northeastern Japan were rattled by a massive magnitude 7.7 earthquake off the coast and warned of possible tsunamis, as well as a slim chance of a magnitude 8 or higher ...

Earthquakes and imaged magmatic dike intrusion. Dots show machine-learning relocated earthquakes from 1 January to 28 February 2025 color-coded according to occurrence time (OTime). Orange patches ...

Recently, while analyzing strong-motion data close to fault lines, a group of researchers at Kyoto University noticed something unexpected: a negative phase in the waveforms, a pattern that did not ...

The magnitude of an earthquake depends on how far a rupture travels along a fault line before it stops. For the first time, we have now directly observed how a large earthquake comes to a halt. By ...

A mysterious swarm of earthquakes that occurred near the Greek island of Santorini in early 2025 was caused by rebounding sheets of magma slicing through Earth's crust, according to a new study by an ...
