Hurricane Season

This website discusses the science of hurricanes and what people can do to be informed and prepared for storms. Information includes news stories on past and predicted hurricanes, hurricane science, ...

Discover Dialogue: Meteorologist William Gray

In this interview published by Discover Magazine, meteorologist William Gray discusses the science of hurricane forecasting, one that he pioneered. Gray, who is a professor of atmospheric science and ...

WINDS: Measuring Ocean Winds from Space

This website provides access to images and data gathered by the SeaWinds scatterometer, a microwave radar sensor designed specifically to measure ocean near-surface wind speed and direction. The site ...

Wind Erosion Research Unit

This website provides a synopsis of wind erosion, which can threaten the sustainability of natural resources. The USDA Wind Erosion Unit provides maps of areas at risk for wind erosion and drought, ...

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 ...

Cracks from a Japanese earthquake heal in two years

This resource provides an abstract. Seventeen years of shockwave recordings were used to investigate crack healing after the large March 1997 Tokai region earthquake in Japan. Recordings taken at two ...

Molten rock makes big earthquakes bigger

This resource provides an abstract. A modified friction welding device was used to spin one small cylinder of granite against another at high speed and pressure in order to simulate two plates ...

Improving earthquake warning in Costa Rica

This resource provides an abstract. This study examines seismic waves from a segment of the Middle America subduction zone below Central America that are capable of producing strong earthquakes. ...
