Activity at Halema‘uma‘u crater increased this morning to include the nearly continuous emission of ash with intermittent stronger pulses that form occasional higher plumes 1-2 kilometers (3,000 to 6,000 feet) above the ground. This photo shows the ash plume at about 9 a.m. HST. Tradewinds this morning are blowing the ash generally to the southwest toward the Ka`u Desert. The dark area to the right of the ash column rising from the Overlook crater is ash falling from the ash cloud to the ground. Photo taken Tuesday, May 15, 2018 courtesy of U.S. Geological Survey
