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, Reuters reported on Sunday. Two reports were published in the journal Nature Geoscience that follow different paths but ultimately conclude the fault that was originally blamed for the earthquake was not the real source, and it is still a real threat. "As the Enriquillo-Plantain Garden fault did not...

Scientists say the earthquake that took place in Haiti was caused by a previously unknown fault. The researchers say that this discovery could be the first sign of a larger system of seismic faults in the area.  The fault that runs through Port au Prince, which is also known as the Enriquillo fault, was originally blamed for the earthquake. Eric Calais presented the findings at the American Geophysical Union's Meeting of the Americas in Foz do Iguacu, Brazil.  He explained that...

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. Rapid response missions can be critical for assessing future risks because a fault can continue to displace the ground for weeks and months after a large...

Geoscientists will collect crucial data for future hazard assessment 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 geologists will collect crucial data to assess whether the quake could trigger another major event to the east or west of Port-au-Prince, Haiti's capital. Eric Calais, a Purdue University geophysicist leading the team, said that most aftershocks occur within...

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 team from Purdue and Northwestern universities analyzed the fault motion for eight years using global positioning system measurements and found that it is much less than expected given the 500- to 1,000-year repeat cycle for major earthquakes on that fault. The last large earthquakes in the New Madrid seismic zone were magnitude 7-7.5 events in 1811...

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. Calais said the event left a wall of magma 6...

WEST LAFAYETTE, Ind. - 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. Eric Calais, an associate professor of geophysics at Purdue University, in collaboration with Ming Wang and Zenghang Shen from the Institute for Geology and Earthquake Science in China, used global positioning systems to record the precise movements of hundreds of points on the continent...
