Kyoto, Japan -- 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 ...

Since the U.S. Geological survey upgraded its earthquake monitors in northwest Louisiana, its earthquake map is showing much ...

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 ...

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, ...

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 ...
