(2009-11-24) Study uses satellite imagery to identify active magma systems in East Africa's Rift Valley A team from the University of Miami, University of El Paso and University of Rochester have employed Interferometric Synthetic Aperture Radar (InSAR) images compiled over a decade to study volcanic activity in the African Rift. The study, published in the November issue of Geology, studies the section of the rift in Kenya. (2009-11-05) African Desert Rift Confirmed as New Ocean in the Making In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial. (2009-11-03) HyBIS explores the Casablanca seamount In October, the hydraulic benthic interactive sampler HyBIS maintained by the National Oceanography Centre, Southampton (NOCS) made ten dives over the Casablanca Seamount, a four-kilometre high seamount located some 300 miles west of Morocco. (2009-11-02) Tsunami waves reasonably likely to strike Israel "There is a likely chance of tsunami waves reaching the shores of Israel," says Dr. Beverly Goodman of the Leon H. Charney School of Marine Sciences at the University of Haifa following an encompassing geo-archaeological study at the port of Caesarea. "Tsunami events in the Mediterranean do occur less frequently than in the Pacific Ocean, but our findings reveal a moderate rate of recurrence," she says. (2009-10-26) Scientists measure the rate of ascent of volcanic magma Plinian volcanic eruptions are notoriously destructive. These very powerful eruptions often occur after long periods of quiescence and are preceded by relatively short periods of seismic restiveness. (2009-10-09) Researchers to study rebirth of an island after volcanic eruption When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. (2009-08-07) UB Geologists to Help Communicate the Dangers of Colombian Volcano During the past decade, residents of Pasto, Colombia, and neighboring villages near Galeras, Colombia's most dangerous volcano, have been threatened with evacuation, but compliance varies. (2009-07-01) Obsidian 'trail' provides clues to how humans settled, interacted in Kuril Islands Archaeologists have used stone tools to answer many questions about human ancestors in both the distant and near past and now they are analyzing the origin of obsidian flakes to better understand how people settled and interacted in the inhospitable Kuril Islands. (2009-06-23) CU-Boulder study shows Maya intensively cultivated manioc 1,400 years ago A University of Colorado at Boulder team has uncovered an ancient and previously unknown Maya agricultural system -- a large manioc field intensively cultivated as a staple crop that was buried and exquisitely preserved under a blanket of ash by a volcanic eruption in present-day El Salvador 1,400 years ago.
