Topography Reflects Baja Quake Site's Complex Geology

(PhysOrg.com) -- The fault responsible for the Jan. 12 magnitude 7.0 earthquake that devastated Haiti is visible in images created using NASA radar topography data acquired in 2000.

(PhysOrg.com) -- JPL's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) captured this false-color composite image of the city of Port-au-Prince, Haiti, and the surrounding region on Jan. 27, 2010. ...

Culminating more than four years of processing data, NASA and the National Geospatial-Intelligence Agency (NGA) have completed Earth's most extensive global topographic map. The data, extensive enough to f ...

A new study adds to evidence that the fault responsible for the 1989 Loma Prieta earthquake is not as unusually weak as had been thought.

The underlying structure of a fault determines whether an earthquake rupture will jump from one fault to another, magnifying its size and potential devastation. Understanding why some earthquakes terminate along a fault, ...

In the last few years there has been a growing number of documented cases in which large earthquakes set off unfelt tremors in earthquake faults hundreds, sometimes even thousands, of miles away.

(AP)—One of Alaska's most restless volcanoes has shot an ash cloud 15,000 feet into the air in an ongoing eruption that has drawn attention from a nearby community but isn't expected to threaten air traffic.

NASA's Tropical Rainfall Measuring Mission satellite known as TRMM measured Cyclone Mahasen's rainfall rates from space as it made landfall on May 16. Mahasen has since dissipated over eastern India.

The first tropical storm of the Eastern Pacific hurricane season was short-lived. Satellite imagery revealed that Tropical Storm Alvin became a remnant low pressure area 36 hours after it was named.

Why Tibetan antelope can live at elevations of 4,000-5,000m on the Qinghai-Tibetan Plateau? In a collaborative research published in Nature Communications, investigators from Qinghai University, BGI, and other institutes provid ...

Short, sharp fluctuations in the Earth's climate throughout the last ice age may have stopped trees from getting a foothold in Europe and northern Asia, scientists say.

The massive ball of iron sitting at the center of Earth is not quite as "rock-solid" as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet's ...
