As Magma Rises Rapidly, Cornell Experts Monitor Ancient Uturuncu Volcano

03.11.2011
Matt Pritchard, Cornell associate professor of geology, is part of an international effort to study Bolivia’s Uturuncu volcano, where the magma is uplifting rapidly.

Cornell graduate students Jennifer Jay and Scott Henderson are part of the research team. Uturuncu last erupted about 300,000 years ago.

Pritchard says:

“Uturuncu — a volcano in the Bolivian Andes Mountains — was thought to be inactive. The region is populated by ‘supervolcanoes’ that erupted between 1 and 10 million years ago.

“Now the Uturuncu magma is accumulating in the crust and we’re observing whether it is moving upward toward the surface. Right now, we have no reason to think that an eruption is imminent.

“The area at Uturuncu has had hundreds of shallow earthquakes per year, but the rate of earthquakes increased briefly due to last year's tremors in Chile. These characteristics are unusual for a volcano that has not erupted in 300,000 years.”

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
