Sutopo Purwo Nugroho, Head of the Information Data Center and Public Relations of the National Disaster Management Agency (BNPB) said that on Sunday the volcano located in the Sunda Strait, Lampung Province, had been erupted almost every day.
Mount Anak Krakatau’s Observation Post, Volcanology Center and Geological Disaster Mitigation (PVMBG) reported that there were 576 eruptions during the day on Saturday, August 18. The eruption height varies, 100 meters to 500 meters from the top of the crater.
For 24 hours from 12:00 am to 12:00 pm on Saturday, the volcano erupted 576 times with an amplitude of 23-44 mm, and the duration of the eruption was 19-255 seconds. It was accompanied by a burst of volcanic ash, sand, flares of incandescent stones, and the sound of a bang. Visually, there were fires and incandescent lava. The blowing lasted 80 times, with an amplitude of 5-30 mm and 10-80 seconds duration.
