Monte Lawu

The Lawu volcanic complex includes a deeply eroded volcano to the south joined to a younger edifice to the north considered by van Bemmelen (1949b) to be probably Holocene. No eruptions or dated deposits are known, but it was mapped by Sampurno and Samodra (1997) as Holocene. The southern end of the broad 3-km-long summit of the younger edifice contains eroded crater rims and a lava dome that fed flows 3.5 km down the S flank. A fumarolic area is also located on the S flank. A small cone with a crater is present on the lower SE flank of the older edifice, ~19 km from the summit. An event was reported in November 1885 CE, with booms, rumbling sounds, and "ash rain" later in the day; this was similar to a landslide reported in 1978. A major eruption attributed to Lawu in 1752 CE was actually from Kelud volcano.
