Through the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157), the USGS received Supplemental funding to support recovery and rebuilding activities in the wake of the 2018 Kīlauea volcano eruption. Supplemental funding will enable the USGS to conduct scientific investigations of the current state of Kīlauea to properly interpret the data from the monitoring networks and characterize the ongoing and future threats and hazards to Hawai‘i Volcanoes National Park and surrounding communities.
Scientific investigations of the current state of Kīlauea are needed to properly interpret the data from the monitoring networks and characterize the ongoing and future threats and hazards to Hawai‘i Volcanoes National Park and surrounding communities. An integrated program of geophysical, geochemical, and geologic investigations are necessary to understand the shallow magma reservoir status and evolution post-2018. This work will improve our understanding of summit and rift zone structure and magmatic plumbing, the history and likelihood of dangerous explosive eruptions from the summit region, and our understanding of the rift zones where the greatest concentration of risk exists on Kīlauea. Seventeen different research projects are supported.

Activity Description/Goal: This study will provide a new detailed view of shallow subsurface structures and the magma system beneath Kīlauea volcano’s summit.
Activity Timeline:
June 1-9, 2023: Seismic node retrieval within Hawaiʻi Volcanoes National Park (HVNP)
May 9-30, 2023: Operation of Vibroseis truck
May 1-8, 2023: Seismic node deployment within Hawaiʻi Volcanoes National Park (HVNP)
