HVO scientists participate in American Geophysical Union Fall Meeting

Kīlauea Volcano's summit lava lake was just one of many topics that USGS Hawaiian Volcano Observatory scientists talked about at the recent American Geophysical Union meeting in San Francisco. HVO webcams captured this small explosion triggered by rocks falling from the Halema‘uma‘u Crater wall into the lava lake on May 3, 2015, when the lake surface was just below the vent rim. USGS image.
