The Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported an eruption on Mount Anak Krakatau located in the waters of the Sunda Strait, Lampung.

Krakatau Children's Observation Post officer Deny Mardiono said the eruption occurred at 05.19 WIB, Thursday (11/5).

"The height of the eruption column was observed at approximately 3,000 meters above the peak. The ash column was observed to be gray with thick intensity leaning towards the southwest," Deny said as quoted by ANTARA.

Deny explained that the eruption was recorded on a seismogram with a maximum amplitude of 70 millimeters and a duration of approximately 2 minutes 12 seconds. According to him, the eruption did not hear a boom.

Mount Anak Krakatau is at level III or standby status which has been set since April 24, 2022.

PVMBG recommends that people, visitors, tourists, and climbers not approach the volcano or move within a five-kilometer radius of the active crater.

Since the birth of Mount Anak Krakatau in June 1927 until now, eruptions have occurred repeatedly, so that Mount Anak Krakatau grows bigger and higher.

The eruption characteristics of Mount Anak Krakatau are in the form of explosive eruptions and effusive eruptions with eruption breaks ranging from one to six years.

The eruptions produce volcanic ash and incandescent lava and lava flows that slowly build the volcano's body.
