Co-eruptive seismic data

In the past I have measured the mass ejection rates of explosive eruptions from the seismic waves and, more recently, constrained the basal friction of volcanic landslides (Brodsky et al., 1999; Brodsky et al., 2003) . In the future, we plan to use modern match-filter techniques to extract seismicity from notoriously messy co-eruptive seismograms. No one has ever been able to see earthquakes during an eruption before. If we succeed in extracting these events, we will have a new, fundamental constraint on the brittle processes during eruptions. I hope to use this tool to examine conduit growth and subsequent failure, which are two of the most important (and most poorly constrained) processes that determine the course of an eruption.
