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.

Estimating Hurricane-Force Winds

This resource provides an abstract: To better measure hurricane-force winds, the authors studied various types of synthetic aperture radar (SAR) wind retrieval schemes applied to the high winds ...

Hurricane intensification may be related to eyewall precipitation

This resource provides an abstract. The authors used weather surveillance radars along the United States coast to study the frequency of tall precipitation in order to quantify the relationship ...

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 ...

Corrections of the Indian gauge data used for early assessments of the great 26 December 2004 earthquake

This resource is an abstract. This study re-evaluates slip velocity over the region of the December 26, 2004 Sumatra-Andaman earthquake. Using new data, the authors found that a mixed mode of slip ...

Tsunami warnings using ocean circulation models

This resource is an abstract. This study uses numerical models that take advantage of digital seismometry and satellite radar altimetry to shed light on tsunami source and formation mechanisms. The ...

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 ...

A tsunami warning system for the Indian Ocean

This resource is an abstract. Using tidal gauge data from the time of the 2004 Indian Ocean tsunami, the authors were able to reconstruct the height and speed of the waves and the time it took them ...

Tsunami "shadows" may allow remote detection of tidal waves

This resource provides an abstract. This study investigates tsunami shadows, extended dark strips on the ocean surface before a tsunami. Such shadows are found to result from an air-sea interaction ...

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 ...

Predicting catastrophic earthquakes

This resource provides an abstract. This article discusses a method based on the magnitude-frequency distribution of previous earthquakes in a region. It is used to examine the probability of a small ...

Reassessing the earthquake threat to San Francisco

This resource provides an abstract. New research suggests that authorities may need to reassess the threat posed by the Hayward fault, the fault responsible for San Francisco's highly destructive ...

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 ...
