Tsunamis Generados por Terremotos en la Zona de Subducción

Mega–terremotos de la Zona de subducción, los terremotos más potentes, pueden producir tsunamis a través de una variedad de estructuras que no son detectadas por los modelos simples. En esta animación exploramos diferentes mecanismos productores de tsunamis examinando tres terremotos famosos: Japón 2011, Chile 2010, y Alaska 2014.

By road, boat, plane and helicopter: Creating a remote seismic measurement network

By road, boat, plane and helicopter: Creating a remote seismic measurement network

The Southern Alaska Lithosphere and Mantle Observation Network (SALMON) is a two-year EarthScope FlexArray project. Using data recorded by 28 of PASSCAL’s broadband seismometers, the goal is to produce images of the crust and upper mantle to better understand active faulting, mantle flow and seismic structure in the Cook Inlet region.
Detecting wind using seismometers

Detecting wind using seismometers

This research team is using seismometers to detect winds (both sustained winds and gusts) across a range of geographical settings.
Increased seismic instrumentation provides insight into the Rio Grande Rift

Increased seismic instrumentation provides insight into the Rio Grande Rift

New seismic stations help answer questions about the extent, deformation pattern and seismic activity of the Rio Grande Rift.
