The 2018 Eruption of Kīlauea Volcano, Hawaiʻi

Date: 4/26/2019

Time: 8:30 AM to 12:00 PM

Room: Puget Sound

The 2018 volcano-seismic activity on Kīlauea, Hawaiʻi manifested in three distinct phases: (1) a magma intrusion along the Lower East Rift Zone, beginning 30 April, resulting in eruptive fissures that eventually produced the highest flow rates ever recorded at Kīlauea; (2) a M6.9 earthquake on 4 May located under the south flank of Kīlauea; the second largest event in Hawaii instrumented history; and (3) the episodic collapse of Halemaʻumaʻu crater at the Kīlauea summit from mid-May to early-August. Advances in techniques to assess the temporal evolution of seismicity, seismic parameters and structure and to link changes to dynamic shifts in eruption behavior, are exciting advances in monitoring, particularly techniques that do so in a largely automated fashion. This session will focus on improving our scientific understanding of seismicity with respect to volcanic and tectonic activity at Kīlauea, the 2018 M6.9 event, caldera collapse processes and advances in techniques that address the temporal evolution of seismic parameters that may accompany these eruptive phases. We invite contributions that include new observations, modeling and other pertinent studies. Topics include, but are not limited to: automated or semi-automated location methods, source rupture processes, foreshock and aftershock studies, early warning systems and geophysical imaging. We seek contributions from diverse fields to facilitate a multi-disciplinary discussion.
