Seismic event generates weak plume captured by Halemaʻumaʻu webcam on June 18, 2018.

On June 18, 2018, at 6:13 AM, a seismic event occurred at Halema‘uma‘u that produced a relatively ash-poor gas plume that rose about 1,600 feet above the crater. The activity was captured by the Halema‘uma‘u Wide Angle webcam located in the USGS–Hawaiian Volcano Observatory Observation Tower. The plume dissipated quickly.
