| Summary: | Anak Krakatau Volcano is the only active volcano on Krakatau Volcanic Complex. It is located in the Sunda Strait as part of the Quaternary volcanic arc as a result of the Indo-Australian plate subduction under the Eurasian plate. The volcanic activity of the Anak Krakatau volcano since 1927 is considered to be very active with a combination of explosive and effusive eruptions. Lava flow tends to be concentrated in the southwestern part, except for the 1996 lava flow (north) and 1993 lava flow (northeast). In 2018 there was an eruption accompanied by flank collapse on the southwestern side, caused by the accumulation of the instability volcanic body due to volcanic and tectonic activity. The volcanic activity will be reflected in the resulting deposits. This study was conducted to determine the characteristics of the deposits, especially on the northern part for post-1996. The analysis carried out included the stratigraphic columns, granulometric, petrography, and geochemistry analysis. |
