Could geometry offer a new explanation for why earthquakes happen?

Magnified through a microscope, diatoms, which are a type of siliceous microalgae preserved within sediment, helped the researchers determine the salinity levels of the core samples. Photo courtesy of Jessica DePaolis.

Subduction zone splay faults compound hazards of great earthquakes

Researchers used unmanned aerial vehicle images superimposed on centimeter-resolution topography to study the surface rupture of the 2021 magnitude 7.4 Maduo earthquake in China. This image shows the fault scarp, tensional cracks on the hanging wall, and the left-laterally offset channel. Credit: Yanxiu Shao

Fault maturity or orientation: Which matters more for quakes?

Shears — or breaks caused by strain — in rock outcrops like the one pictured here could shed new light on tectonics that occur between major earthquakes in the subduction zone, according to new research. A camera lens shows the scale of the features of the rock. Credit: Provided by Donald Fisher . All Rights Reserved.
