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 ...

The Mw 8.3 deep-focus earthquake beneath the Okhotsk Sea in 2013 provides an opportunity to study the source mechanism with regard to the specific geometry of the slab in the hypocentral region. It is ...

Topographic amplification is caused by the interaction between seismic waves and rough terrains. It increases shaking levels on hilltops and could lead stable slopes to the brink of failure. However, ...

Scientists have confirmed that a mysterious Utah earthquake first detected in 1979 really did occur nearly 90 kilometers underground—far deeper than anyone thought earthquakes could happen beneath a ...

A new report studied a massive earthquake that ruptured in the southeast Asian country of Myanmar on March 28 — on a fault known for being eerily similar to California’s notorious San Andreas fault.
