Mount Anak Krakatoa

Anak Krakatau is a volcanic island in Indonesia that emerged from the caldera of the 1883 Krakatoa eruption on 29 December 1927. The island has been subject to sporadic eruptive activity since its emergence, culminating in a large underwater collapse in December 2018 that caused a deadly tsunami. Prior to its collapse, the island's highest point had increased at an average rate of 7-9 meters per year, and its maximum elevation had reached 338 meters. The island is contained within the Ujung Kulon National Park and is part of the Pacific Ring of Fire.learn more on wikipedia
