Forecasting Seismicity from Wastewater Disposal in Oklahoma
Mandated wastewater injection reductions in effect since 2016 are inadequate for preventing future, large-magnitude earthquakes in the state, according to a new induced seismicity model.

Varying Impact of Earthquake- and Monsoon-Induced Landslides
Using nearly 50 years of satellite data and records stretching back millennia, scientists determine the relative frequency—and the erosional power—of monsoon- and earthquake-induced landslides in Nepal.

Ancient Faults Amplify Intraplate Earthquakes
A comparison of deformation rates from Canada’s Saint Lawrence Valley offers compelling evidence that strain in the region is concentrated along ancient structures from previous tectonic cycles.

Unraveling the Origin of Slow Earthquakes
Different nucleation styles detected in five slow-slip events in the same area of Japan’s Ryukyu subduction zone suggest the physical properties along this tectonic plate interface change over time.

Can Earthquakes Trigger Volcanic Eruptions?
A new study supports the idea that earthquakes may be associated with increased volcanic eruptions, but over longer time spans than prior research indicated.

Watch Tiny Cracks Travel in 3-D
Scientists used a transparent gel and high-speed photography to figure out how cracks form and spread. What they found could help explain earthquakes and fracturing glaciers.

In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.
