Several flavors of seismogenic magma movement under Kilauea Volcano
Dr. Weston Thelen, USGS Cascade Volcano Observatory

ABSTRACT

Kilauea has long been a target of study because of its high rates of volcanic activity and long history of monitoring. We look at different seismic signatures of magma movement at different places in the upper mantle and crust under Kilauea Volcano. This includes tremor at depths greater than 50 km, repeating earthquakes in the conduit at 3 km depth and seismically derived tilt signals near the surface of the lava lake.

At the end of this webinar, students should be able to:

  • Define the different seismic signatures of magma movement at different places in the upper mantle and crust under Kilauea Volcano
  • Describe the tremor at depths greater than 50 km, repeating earthquakes in the conduit at 3 km depth and seismically derived tilt signals near the surface of the lava lake
