New system can warn of tsunamis within minutes
Seismologists have developed a new system that could be used to warn future populations of an impending tsunami only minutes after the initial earthquake. The system, known as RTerg, could help reduce the death toll by giving local residents valuabl…
Scientists find increase in microearthquakes after Chilean quake
By studying seismographs from the earthquake that hit Chile last February, earth scientists at the Georgia Institute of Technology have found a statistically significant increase of microearthquakes in central California in the first few hours after…
If greenhouse gas emissions stopped now, Earth still would likely get warmer
While governments debate about potential policies that might curb the emission of greenhouse gases, new University of Washington research shows that the world is already committed to a warmer climate because of emissions that have occurred up to no…
New drought record from long-lived Mexican trees may illuminate fates of past civilizations

Pakistan floods last summer could have been predicted
WASHINGTON — Five days before intense monsoonal deluges unleashed vast floods across Pakistan last July, computer models at a European weather-forecasting center were giving clear indications that the downpours were imminent. Now, a new scientifi…
A clearer picture of how rivers and deltas develop
By adding information about the subsoil to an existing sedimentation and erosion model, researchers at Delft University of Technology (TU Delft, The Netherlands) have obtained a clearer picture of how rivers and deltas develop over time. A bette…
Improved measurements of sun to advance understanding of climate change
WASHINGTON — Scientists have taken a major step toward accurately determining the amount of energy that the sun provides to Earth, and how variations in that energy may contribute to climate change.
In a new study of laboratory and satellite …
