The USGS Hawaiian Volcano Observatory, along with its partners at the National Oceanic and Atmospheric Administration’s Pacific Tsunami Warning Center and the National Strong-Motion Project, operates a network of seismic monitoring stations on the Island of Hawaii and throughout the state.

Volcano Watch: USGS to survey Kilauea from summit to Kumukahi

Since the end of 2018’s volcanic activity, USGS Hawaiian Volcano Observatory scientists have wanted to resurvey Kilauea Volcano’s ground surface to document changes brought about by the Puna eruption and summit collapse. Doing so would allow us to more accurately answer questions about the total volumes of erupted lava and summit subsidence that occurred last summer.

This led to beautifully clear skies gracing the Island of Hawaii, particularly noticeable on the west side, where the volcanic pollution known as vog chronically collected in past years.
