Dense Virtual Seismic Array at Pacaya

Our goal is do generate a set of recordings for a dense network of stations to study structure and source processes of strombolian eruption activity, tremor, and long-period earthquakes at Pacaya volcano. Because installing and maintaining 80 stations is extremely challenging, we will record at 80 sites using 20 stations and moving a subset each day in a manner we have had success with elsewhere. For repetitive events, we will combine recordings at all sites for dense, 80-station records.
