A new analysis of historical seismic data led by The University of Texas at Austin has found that earthquake activity in West Texas near the city of Pecos has increased dramatically since 2009. The study, published Nov. 4 in the Journal of Geophysical Research: Solid Earth, is important because it leverages old, unmined data to… Continue Reading Historical Data Confirms Recent Increase in West Texas Earthquakes
New NSF Grant Awarded to Study Earth’s “Flat Slabs”
A $2.7 million multi-disciplinary, multi-institutional NSF-Frontiers of Earth Science grant has been awarded to a team led by Carnegie’s Lara Wagner to study an active flat slab in Colombia. A flat slab is produced when a tectonic plate descends to depths of about 30 to 60 miles (~50-100 km) then flattens and travels horizontally for… Continue Reading New NSF Grant Awarded to Study Earth’s “Flat Slabs”
New Computer Modeling Approach Could Improve Understanding of Megathrust Earthquakes
Years before the devastating Tohoku earthquake struck the coast of Japan in 2011, the Earth’s crust near the site of the quake was starting to stir. Researchers at The University of Texas at Austin are using computer models to investigate if tiny tremors detected near the site of the quake could be connected to the… Continue Reading New Computer Modeling Approach Could Improve Understanding of Megathrust Earthquakes
From the Field: Installing Seismic Sensors in the Mojave Desert
Rob Porritt, a UTIG postdoc, along with three UT Geology undergraduate students traveled to the Mojave desert in California in May to deploy 19 broadband seismic sensors. All were successfully placed over the course of six arduous days in the desert. “This was by far the hardest deployment I’ve ever done,” said Rob. “We stressed… Continue Reading From the Field: Installing Seismic Sensors in the Mojave Desert
The Earthquake That Changed Science and a State
To most people, 50 years might seem like a long time to look back. That isn’t the case for many residents of our 49th state, Alaska — especially not on this day. It was on this day in 1964, at 5:36 p.m. Alaskan Standard Time, that a fault rupture triggered the most powerful earthquake in… Continue Reading The Earthquake That Changed Science and a State
