Rick Bennett Receives NSF Grant to Study Aseismic Fault Slip in Italy

Rick Bennett sits on a large rock in Italy

With a grant of more than $520K from the National Science Foundation, Richard Bennett and a team of researchers will deploy a network of multi-sensor instruments in shallow boreholes capable of detecting the small signals associated with slow aseismic fault slip in central Italy. The data collected will provide valuable new insights into the mechanisms that control earthquakes and faulting, with important implications for earthquake hazards assessment and the physics of earthquakes and faulting.

Geosciences Team Receives Grant from W.M. Keck Foundation to Study Subsurface Fluids

A group of researchers stand on orange sandstone

With a three-year, $1M Keck Foundation grant, a UA Geosciences team will integrate geologic, geochemical, geochronologic and hydrogeologic observations and develop an integrated, interdisciplinary understanding of subsurface fluid-rock systems. Focusing on the Paradox Basin, the researchers will use the distributions, ages and geochemical compositions of accumulations of metals and hydrocarbons, altered rocks and trapped paleofluids, together with geophysical models, to understand the integrated history of paleofluid flow over the 300-million-year history of the basin.

Spence Titley Featured in Arizona Daily Star

 Spencer Titley sits holding a blue Davis-Monthan log book.
Spencer Titley and his logbook with signatures from pilots who flew into Davis-Monthan Aviation Field, as it was then called, were featured in the September 10 Arizona Daily Star. The Star calls the logbook, "A veritable 'who’s who' of early aviators." Through his work with NASA astronauts, Titley also has a log book of pilots who walked on the moon.
