80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse
New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. In 2012, a 6.5-mile crack formed in about 5 and a half minutes, showing that ice shelves can effectively shatter, though the speed of breakage is reduced by seawater rushing in. These results can help improve ice-sheet models and projections for future sea level rise.

Q&A: How ‘slow slip’ earthquakes may be driven by deep hydraulic fracturing
New research confirms the cause of slow slip along the Cascadia Subduction Zone and other faults that is accompanied by intermittent tremors or “pops” at the surface. Co-authors Marine Denolle and Joan Gomberg discuss the role of fluid-driven fracturing deep underground.

New UW Photonic Sensing Facility will use fiber-optic cables for seismic sensing, glaciology and more
A University of Washington pilot project is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, a nonprofit based in Vancouver, Washington, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
