The Deep Roots of Catastrophe

A University of Utah seismologist analyzed seismic waves that bombarded Earth’s core, and believes he got a look at the earliest roots of Earth’s most cataclysmic kind of volcanic eruption. But don’t worry. He says it won’t happen for perhaps 200 million years.

Russian Far East Holds Seismic Hazards That Could Threaten Pacific Basin

Research shows that the Kamchatka Peninsula and Kuril Islands, long shrouded in secrecy by the Soviet government, are a seismic and volcanic hotbed with a potential to trigger tsunamis that pose a risk to the rest of the Pacific Basin.

Traveling Through a Volcano

Scientists widely believe that volcanic particle size is determined by the initial fragmentation process, when bubbly magma deep in the volcano changes into gas-particle flows. But new Georgia Tech research indicates a more dynamic process where the amount and size of volcanic ash actually depend on what happens afterward, as the particles race toward the surface.

Volcanoes Sound-Off on the Life-Cycles of Eruptions

Volcanoes emit a broad spectrum of sonic energy. In the case of basaltic eruptions, most of that acoustical energy in the infrasound range. A new study reveals that this low-frequency sound can give scientists an enhanced understanding of the behavior of volcanoes and a tool to monitor the lifecycles of their eruptions.

Una Fuente De Lava y Dos Volcanes: Estudiante de la Universidad De Cornell Conduce una Investigación Geofísica en Chile

Jennifer Jay es estudiante de postgrado en la Universidad de Cornell, estudiando la geofísica, o sea, la física de la Tierra, con una especialidad en el volcanismo de la cordillera de los Andes. Ella trabaja con el professor Mattew Pritchard y otro estudiante de postgrado, Scott Henderson. Dentro de pocos días, ellos viajarán a Chile para hacer una investigación geofísico de la región volcanica llamaba Lazufre. Trabajarán con un equipo de geofísicos de la Universidad de Alaska, Fairbanks, y unos colaboradores chilenos

As Magma Rises Rapidly, Cornell Experts Monitor Ancient Uturuncu Volcano

Matt Pritchard, Cornell associate professor of geology, comments as part of an international effort to study Bolivia’s Uturuncu volcano, where the magma is uplifting rapidly. Uturuncu last erupted about 300,000 years ago.
