Preliminary Analysis of the April 2007 Solomon Islands Tsunami, Southwest Pacific Ocean

The tsunami that was triggered by a magnitude 8.1 earthquake on April 1, 2007, in the Solomon Islands caused significant damage and loss of life. In the hopes that disasters such as this can be avoided in the future, we attempt to understand the mechanism and impact of this tsunami. The information presented here is focused on geologic aspects of the disaster.

Mississippi Coastal Improvements Program (MsCIP)

In 2009, the Mississippi Coastal Improvements Program (MsCIP) was developed by the U.S. Army Corps of Engineers (USACE), Mobile District in conjunction with other Federal and State agencies, to help reduce future storm damage along the Mississippi Gulf Coast. The Comprehensive Plan for MsCIP includes restoring the Mississippi barrier islands and over 3,000 acres of wetland and coastal forest...

Alabama Barrier Island Restoration Assessment

This project is a collaborative effort between the USGS, U.S. Army Corps of Engineers (USACE), and the State of Alabama funded by National Fish and Wildlife Foundation (NFWF) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama. The project is focused on restoration options that protect and restore habitat and living...

Faults and Earthquake Geology

To understand the risk that different areas of the U.S. face for earthquake hazards, we need to know where faults are and how they behave. We know a fault exists only if it has produced an earthquake or it has left a recognizable mark on the earth’s surface. Once a fault has been identified, the next step is to determine how it behaves.

Earthquake Hazard and Risk Assessment

Seismic hazard maps integrate what scientists have learned about earthquake sources, crustal deformation, active faulting, and ground shaking to evaluate the earthquake hazards across the country.

Earthquake Processes and Effects

The overarching theme of this research is for scientists to discover as much as they can about earthquakes and faulting from field and laboratory observations, and to combine this with geophysical, geological, geochemical, and mathematical (including computational) modeling of earthquake sources and fault zones so as to best improve USGS earthquake hazard assessments.

Earthquake Monitoring Improvements

A seismometer is an instrument used for detecting ground motion from earthquakes and other seismic sources. These highly sensitive instruments require careful installation, routine calibration, and daily monitoring to ensure the data used by scientists is of the highest quality.
