Muria Volcano | John Seach


Central Java, Indonesia

6.62 S, 110.88 E
summit elevation 1625 m

Muria volcano is located on the north coast of central Java, Indonesia. The volcano is composed of highly potassic lava, tephra and intrusive rocks. The flanks are deeply eroded. The depth of the Benioff Zone is located 400 km beneath the Muria Peninsula.

The central vent contains craters up to 5 km in diameter, aligned along a north-south trend. The flank of the volcano contains up to 25 smaller cones. Genuk Volcano (elevation 670 m) is an eroded dome complex situated at the northern base of Muria. Mt. Patiayam (elevation 350 m) is located 17 km south-southeast of Muria.

A nuclear power plant has been proposed near the base of Muria volcano.

There is evidence that magma is located beneath the volcano, due to gas composition at the base of the volcano. The most recent known activity produced three explosion craters and at least one lava flow on the eastern flanks of Muria volcano.
