Earthquakes

Ground shaking caused by the sudden release of accumulated strain by an abrupt shift of rock along a fracture in the earth or by volcanic or magmatic activity, or other sudden stress changes in the earth.

Computed Tomography (CT) scans of sediment cores collected from Montague Island, AK

This dataset includes computed tomography (CT) scans of sediment cores collected from coastal environments on Montague Island, Alaska. The cores were collected with hand driven peat augers to assess environmental changes related to tectonic uplift caused by historic and prehistoric earthquakes.

High resolution double-difference relocations of earthquakes in and offshore Puerto Rico and Virgin Islands during the deployment of ocean bottom seismometers from mid-2015 to mid-2016

Puerto Rico is a Caribbean Island with a population of about 3.2 million people who are exposed to natural hazards including earthquakes and submarine landslides that can generate tsunamis. Previous work has shown seismicity offshore Puerto Rico especially between the coastline and the Puerto Rico Trench north of the island. The Puerto Rico Seismic Network maintains the local seismic network to record earthquakes, but these earthquake locations rely on seismic instruments that are all located on land. As ...

Hydrodynamic and sediment transport tsunami models at the Salmon River estuary, Oregon

This portion of the USGS data release describes the Delft3D-FLOW model application for propagating simulated tsunamis from 15 hypothetical earthquake sources of the Cascadia Subduction Zone through a series of nested grids to modeling tsunami sediment transport in the Salmon River estuary, OR. Input files necessary to run the Delft3D-FLOW model are provided. The model application was constructed using Delft3D-FLOW. Zip files containing model setup data are provided for each of the nested hydrodynamic grids ...

Quaternary faults offshore of California

A comprehensive map of Quaternary faults has been generated for offshore of California. The Quaternary fault map includes mapped geometries and attribute information for offshore fault systems located in California State and Federal waters. The polyline shapefile has been compiled from previously published mapping where relatively dense, high-resolution marine geophysical data exist. The data are also available in kml format and are accompanied by a pdf containing citations for the compiled source data. In ...
