the remnant structure. The crater, which had become open to the sea immediately after the eruption, had a complete rim above sea level. In May 2019, phreatomagmatic activity was observed around the newly reconstructed crater as the volcano continued to increase in height and remodel the areas destroyed in 2018. 2020 eruption Anak Krakatoa began erupting again on the morning of 10 April 2020. The first eruption could be heard in the Indonesian capital of Jakarta, over away, and was spewing out a high column of ash and smoke according to the Center for Volcanology and Geological Disaster Mitigation's (PVMBG) magma volcanic activity report, which also said that the first eruption lasted one minute and 12 seconds starting at 9:58 p.m. The eruption spewed ash to about and a secondary ash plume made it to about . The eruption was largely magmatic with lava fountains visible. No widespread damage was reported, and the eruption ended several hours later. 2022 eruption Anak Krakatoa presented a minor eruption on 4 to 5 February 2022.
