U.S.-led team confirms an Alps-like mountain range exists under east Antarctic ice sheet Capstone of NSF-supported International Polar Year Feb. 25, 2009 -- Download Flying twin-engine light aircraft the equivalent of three trips around the globe and working in temperatures that averaged minus 30 degrees Celsius, an international team of scientists, including one from Washington University in St. Louis, has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice. Douglas A. Wiens, Ph.D., WUSTL professor and chair of earth and planetary sciences, is part of the seismology team.

Seeking the oldest ice Wiens heads seismology effort in international Antarctic study Oct. 21, 2008 -- Douglas A. Wiens, Ph.D., professor and chair of earth and planetary sciences in Arts & Sciences, will head the seismology research team of an ambitious international effort to map and analyze an unknown part of Antarctica. The project is called AGAP (Antarctica's Gamburtsev Province) after the Gamburtsev Subglacial Mountains, which are the main feature of the region. Wiens, Patrick Shore, computer specialist in earth and planetary sciences, and graduate students David Heizel and Amanda Lough will install 26 seismographs on the frozen surface of central Antarctica, a part of the world that is a geological mystery.

Antarctica's slip is showing Data show Antarctic ice stream radiating seismically June 4, 2008 -- Image courtesy of Doug Wiens Douglas Wiens (left), and a colleague ready equipment to emplace seismographs in Antarctica during a 2001 expedition. A seismologist at Washington University in St. Louis along with colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that make California's earthquake problem seem trivial. Douglas A. Wiens, Ph.D., professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses to reveal two bursts of seismic waves from an ice stream in Antarctica every day, each one equivalent to a magnitude seven earthquake.

All shook up Midwest now worries about a different fault April 24, 2008 -- Two seismologists at Washington University in St. Louis think the New Madrid Fault may have seen its day and the Wabash Fault is the new kid on the block. "I think everyone's interested in the Wabash Valley Fault because a lot of the attention has been on the New Madrid Fault, but the Wabash Valley Fault could be the more dangerous one, at least for St. Louis and Illinois," said Doug Wiens, professor of earth and planetary sciences in Arts & Sciences. "The strongest earthquakes in the last few years have come from the Wabash Valley Fault, which needs more investigation."

Surprise: No tsunami Tonga quake not conducive to tsunami March 5, 2007 -- The figure shows the dynamics of a slab-tear earthquake (top), compared with a shallow thrust earthquake (bottom). The slab-tearing event typically doesn't feature an accompanying tsunami. Download Seismologists at Washington University in St. Louis and their colleagues in Australia, Japan and Tonga have determined why a large earthquake in Tonga did not cause a large tsunami. A tsunami warning was issued around the Pacific Rim following the magnitude 8.0 earthquake on May 3, 2006, but the resulting tsunami was very minor and caused no damage.

As Ice Melts, Antarctic Bedrock Is On The Move SpaceDaily.com Dec. 30, 2008 -- Scientists have discovered that as ice melts away from Antarctica, parts of the continental bedrock are rising in response - and other parts are sinking. These results come from POLENET, a growing network of GPS trackers and seismic sensors implanted in the bedrock beneath the West Antarctic Ice Sheet. WUSTL is one of the partners.

Huge mountain range shouldn't be there MSNBC.com Oct. 22, 2008 -- An Antarctic mountain range that rivals the Alps in elevation will be probed this month by an expedition of scientists. Researchers from WUSTL and Penn State will contribute to the fieldwork by using seismic recordings of earthquakes to create images of the crust and mantle beneath the mountain range.

Monitoring Antarctic Ice Movement Is a Sticky Business Scientific American June 5, 2008 -- Story on a study of the Whillians Ice Stream in West Antarctica and how it moves. WUSTL earth and planetary sciences professor Douglas Wiens, who is lead author of the study, says his team has uncovered evidence that the mammoth expanse of ice is powered by seismic energy in the watery, rocky terrain beneath it.
