Semeru

Stratovulcano · Indonesia · 3657 m

Semeru volcano rises above the coastal plain in Java, shown here producing a small ash plume in 1985. Larger eruptions occasionally produce pyroclastic flows and lahars that reach as far as the lower flanks of the volcano. Semeru (also known as Mahameru: "Great Mountain") has been in near-continuous activity since 1818.

Sintesi geologica

Semeru, the highest volcano on Java, and one of its most active, lies at the southern end of a volcanic massif extending north to the Tengger caldera. The steep-sided volcano, also referred to as Mahameru (Great Mountain), rises above coastal plains to the south. Gunung Semeru was constructed south of the overlapping Ajek-ajek and Jambangan calderas. A line of lake-filled maars was constructed along a N-S trend cutting through the summit, and cinder cones and lava domes occupy the eastern and NE flanks. Summit topography is complicated by the shifting of craters from NW to SE. Frequent 19th and 20th century eruptions were dominated by small-to-moderate explosions from the summit crater, with occasional lava flows and larger explosive eruptions accompanied by pyroclastic flows that have reached the lower flanks of the volcano.

Sintesi da Wikipedia

Semeru, anche chiamato Gunung Semeru, è la montagna più alta dell'isola di Giava ed uno dei suoi vulcani più attivi. Conosciuto anche come Mahameru, è molto ripido e si erge nettamente sul piano costiero della parte est di Java. Dei Maar contenenti dei laghi vulcanici si sono formati seguendo una linea fino alla sommità. Il Semeru si trova all'estremità sud del complesso vulcanico Tengger.
