HISTORY OF ANAK KRAKATOA VOLCANO 2018
A new eruptive phase was observed on Anak Krakatoa Volcano starting in June 2018; and on 15 October 2018, volcano had a strong Strombolian to weak Vulcanian eruption that sent lava bombs into the water.

An eruption of the volcano on 22 December 2018 caused a deadly tsunami, with waves up to five meters in height making landfall. On 31 December 2018, the disaster agency stated the tsunami's death toll was 437, with 14,059 injured. The tsunami affected more than 300 kilometers of coastline in Sumatra and Java and 40,000 people were displaced. This made the eruption the deadliest volcanic eruption of the 21st century to date. (Mayon death tools 1,266 in 2006 were coused by mudslides).

Anak Krakatoa's Cone collapse—with tsunami generation—was considered a potential hazard immediately before the eruption. Scientists had modeled the possibility six years before the event, and had identified the western flank as the section of the volcano most likely to fail.

Following the December 2018 eruption, it was believed that the southwest sector of the volcano, including the summit, had collapsed during the eruption, triggering the tsunami. On 23 December, this was confirmed by satellite data and helicopter footage, with the main conduit seen erupting from underwater, producing Surtseyan-style activity. The volcano lost over two-thirds of its volume due to this event, and its elevation above sea level was reduced from 338 m to just 110 m.

Satellite radar observations showed that by 10 January 2019, the volcano had continued to form, with further eruptions beginning to re-model 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.

A new eruption started at the Anak Krakatoa, or Krakatau, volcano on Rakata Island in Indonesia on 3 February 2022
