Abstract:We carried out drones photogrammetry on Anak Krakatau in 2013, 2019, 2020 and 2021. Changes in the morphology of Anak Krakatau occurred so quickly as its volcanic activity never stopped. Its pyroclastic cone in 2013 reached a height of 334 meters with a coastline circumference of 6.8 km. The circumference of the pyroclastic cone calculated from the traces of the old crater wall has a volume of 31971 m3. During the 2018 eruption, a large part of the cone was pulverised, resulting in a large crater of 400 m in d… Show more
