Investigating Volcanic and Glacial Processes Using Microseismicity
… volcano, Iceland, before and after an eruption; icequakes at the bed of glaciers and ice sheets to study and constrain the physics of glacial sliding; and surface icequakes caused by crevassing, to see whether or not the crevasses observed are induced by hydrofracture. I use a combination of …

Studies of Seismic Sources in Antarctica Using an Extensive Deployment of Broadband Seismographs
… In West Antarctica I find tectonic earthquakes, icequakes, and tectonic events related to volcanism. I do not find evidence of tectonic events in West Antarctica that would indicate rifting is currently active. I also find two main sources of 'slow' seismicity: calving along Vanderford glacier …

Planetary Seismology using Single-Station and Small-Aperture Arrays: Implications for Mars and Ocean Worlds
… as originating from moulins, drainage events, icequakes, and rockfalls. Both sites had very high frequency events (> 100 Hz) that came from poles left in the field. These studies inform landing site selection criteria, such that there were trades between detecting local seismicity at the …

Tidal and Structural Controls on Seismic Events Near the Grounding Line at Beardmore Glacier, Antarctica
Here I report seismic events occurring over a three-week period during the 2013-2014 austral summer near the grounding line of Beardmore Glacier, Antarctica. The ~24000 events over this time frame had a noticeable temporal pattern that correlates well with the principally diurnal tides of …
