A project being completed within the next few weeks to map California's San Andreas Fault could bring the dream of forecasting earthquakes a bit closer to reality.
Researchers have used measurements of tiny movements in the Earth's crust to gain a better understanding of earthquake dynamics in Nicaragua, where a large quake devastated the city of Managua in 1972. Their findings confirm a prediction of movement in the Earth's surface, but show little perpendicular strain associated with the movement, indicating a lack of coupling between the converging plates despite earthquake activity.
Researchers at the University of Arkansas and Purdue University have monitored tiny tectonic movements in the Caribbean to create the first comprehensive and quantitative kinematic model describing potential earthquake activity in the region.
Analyses of a classic, slow-rupturing tsunami earthquake whose massive waves devastated the coast of Java, Indonesia, this past summer are providing insight to seismologists and engineers, who want to better understand these rare events, recommend strategies to improve safety and perhaps provide long-range forecasts of potential danger zones worldwide.
A University of Arkansas researcher and his colleagues have found that fatalistic religious beliefs can affect how people perceive risk and recover from natural disasters and how these attitudes shape the way cities are rebuilt.
A researcher investigating several facets of the San Andreas Fault has produced a new depiction of the earthquake potential of the fault's southern, highly populated section. The new study shows that the fault has been stressed to a level sufficient for the next "big one""”an earthquake of magnitude seven or greater"”and the risk of a large earthquake in this region may be increasing faster than researchers had believed.
U.S. ports serve as crucial gateways for international trade, but they're particularly vulnerable to damage in an earthquake. A new project led by Georgia Tech aims to develop strategies to help safeguard critical U.S. ports from earthquake damage.
Midwesterners are more used to tornadoes than earthquakes. But the 100th anniversary of the 1906 San Francisco earthquake has some experts at the University of Missouri-Rolla thinking about threats associated with the New Madrid fault in addition to those posed by the San Andreas fault. UMR researchers are available to discuss earthquake-related issues.
Hundreds of earthquakes occur every day around the world, most of them underneath the oceans, while the vast majority of instruments used to record earthquakes are on land. As a result, advances in understanding basic earthquake processes have been limited by the available data.
