Repeating quakes during multiple phases of unrest and eruption

The video describes work by Jay Wellik, a USGS seismologist and his colleagues with the Volcano Disaster Assistance Program (VDAP). They assisted Indonesia's CVGHM in responding to the 2017 activity/eruption at Mt. Agung, on the island of Bali. The work describes use of software to characterize the different types of earthquakes at the volcano, and how that revealed important infrormation about magma ascent and eruption.
