Semeru

Semeru, or Mount Semeru (Indonesian: Gunung Semeru), is an active volcano located in East Java, Indonesia. It is the highest mountain on the island of Java. This stratovolcano is also known as Mahameru, meaning 'The Great Mountain. The name derived from the Hindu-Buddhist mythical mountain of Meru or Sumeru, the abode of gods.

Geology

Known also as Mahameru (The Great Mountain), it is very steep rising abruptly above the coastal plains of eastern Java. Maars containing crater lakes have formed along a line through the summit of the volcano. It was formed south of the overlapping Ajek-ajek and Jambagan calderas. Semeru lies at the south end of the Tengger Volcanic Complex.

Eruptive history

Semeru's eruptive history is extensive. Since 1818, at least 55 eruptions have been recorded (10 of which resulted in fatalities) consisting of both lava flows and pyroclastic flows. All historical eruptions have had a VEI of 2 or 3.

Semeru has been in a state of near-constant eruption from 1967 to the present. At times, small eruptions happen every 20 minutes or so.
