BackgroundThe volcano is elongated in a NNW-SSE direction, parallel to a regional transverse fault perpendicular to the plate boundary. The fault defines a volcanic chain strechting from Merapi volcano in the S to Ungaran volcano in the N.
3 large U-shaped radial valleys NW, NE, and SE extend from the 3145-m-high summit of Merbabu and define 3 sectors. The most recent eruptions originated from a NNW-SSE fissure system that cuts across the summit and fed the large-volume Kopeng and Kajor lava flows on the northern and southern flanks. Moderate explosive eruptions have occurred from the summit crater of Merbabu in historical time.
