National Environmental Policy Act (NEPA) from the US Forest Service

Federal legislation enacted in 1970 requires that government agencies consider the environmental costs of their actions through a process of environmental impact statements and public comment. This ...

Alaska Volcano Observatory

This resource contains general information about the location and activity of volcanoes in Alaska, including St. Paul and St. George Islands.

Improving hurricane prediction

The authors report that a high resolution general circulation model now being used at NASA's Goddard Space Flight Center and Ames Research Center doubles the resolution of most global weather models ...

Oceanic carbon may help track hurricanes

This resource is an abstract. The authors demonstrate for the first time that satellite images of dissolved organic matter may also help researchers approximate the mixing of surface-level ocean ...

Listening to the 2004 Indian Ocean tsunami quake

This resource is an abstract. This study tracks the movement of the rupture that caused the December 26, 2004 Indian Ocean tsunami by comparing recordings of sound waves from five sensors located ...

How volcanic eruptions cause tsunamis

This study investigates the effect of pyroclastic flows on tsunami generation. The authors analyzed several possible mechanisms that occur when the particle rich flows encounter water and conclude ...

Earthquake causes distant tremors off Japan coast

This resource provides an abstract. Japan has a nationwide network to sense tremors triggered from waves that traveled long distances through the Earth�s crust. Data from the 2003 Tokachi-oki ...

Using GPS for earthquake imaging

This resource provides an abstract. The authors used a dense array of Global Positioning System (GPS) stations to model how the Earth slipped during the 2003 8.0-magnitude Tokachi-Oki earthquake near ...

Details of North African tectonics

Global Positioning System (GPS) and ground-based measurements were used to study coastal shoreline movement after the 2003 6.8-magnitude earthquake in Algeria. The authors recorded ground deformation ...

Amplifying seismic waves through the ground

Seismic data from Mexico City indicate that active and passive energy from tremors combined in the 30 meters of soft soil below the city and caused the ground to rock and heave far into central ...

GPS method to track ground movement after earthquakes

Global Positioning System (GPS) coordinates from before and after the 2003 8.0-magnitude Tokachi-Oki earthquake in Japan were used to estimate the slip distribution on the plate boundary. The GPS ...
