The deadly Haiti earthquake that killed upwards of 300,000 people in January may have been caused by a previously unknown fault and pressure could be building for another seismic catastrophe.
Scientists say the earthquake that took place in Haiti was caused by a previously unknown fault.
To help assess the potential threat of more large earthquakes in Haiti and nearby areas, scientists at The University of Texas at Austin's Institute for Geophysics are co-leading three expeditions to the country with colleagues from Purdue University, Lamont-Doherty Earth Observatory, the U.S. Geological Survey and five other institutions.
A team funded by the National Science Foundation (NSF) is returning to Haiti this week to investigate the cause of the January 12, magnitude 7 earthquake there.
The New Madrid fault system does not behave as earthquake hazard models assume and may be in the process of shutting down, a new study shows.
A U.S.-led international team of scientists says it has, for the first time, recorded a geological event that is considered key in shaping the Earth's crust. Led by Purdue University Professor Eric Calais, the researchers said they measured ground displacements as two African tectonic plates moved apart and molten rock pushed its way toward the surface during the first so-called dyking event ever recorded within the planet's continental crust.
New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape.
