Every year, the Earth shakes thousands of times. Most of those tremors go unnoticed, felt only by sensitive instruments buried deep in the ground. Occasionally, though, one of them tears apart cities, ...

Scientists have built a lab model that visually tracks how microscopic contact points between fault surfaces evolve during earthquake cycles, revealing the hidden mechanics behind both the slow ...

On Jan. 1, 2024, a 7.5-magnitude earthquake struck the Noto Peninsula in Japan, resulting in extensive damage in the region caused by uplift, when the land rises due to shifting tectonic plates. The ...

Improving tsunami hazard assessments depends on understanding what happens at the moment an earthquake ruptures beneath the seafloor, especially near deep-ocean trenches where measurements are often ...

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 ...

Scientists used supercomputer simulation to reveal the underlying mechanism by which the irregular fault geometry, characterized by multisegments, controlled the variation of the fault slip and ...
