NEW ANIMATION! Earthquake!! Shaking up Central America

Whereas transform-fault and shallow-crustal-intraplate earthquakes have dominated the recent history of deadly and destructive earthquakes in Central America, we should never underestimate the potential destructive power of subduction zone earthquakes.

SCIENCE AND PROGRAM HIGHLIGHTS

How thick is the lithosphere under the southeastern US?

How thick is the lithosphere under the southeastern US?

 In previous seismic studies, researchers interpreted pockets of relatively slow seismic velocities in the eastern US as evidence for thin, broken-up lithosphere. But, magnetotelluric imaging supports a thick, coherent lithospheric block. Murphy and Egbert (2019) reconcile these seemingly contradictory datasets.
Stormquakes

Stormquakes

 New research presents evidence that strong storms produce seismic surface waves that are distinct and measurable. The name for these newly discovered geophysical phenomenon? Stormquakes.
