Tolire Jaha maar on the lower NW flank formed during a violent eruption in 1775.  The eruption began with explosive activity at the summit on August 20.  On the night of September 5-6, a devastating base surge accompanying formation of the maar was responsible for most of the 141 people that were killed during the eruption.  The steep-walled maar is 700 m wide.  A smaller maar, Tolire Kecil, formed to the NW along the coast during the same eruption. Photo by Ruska Hadian, 1994 (Volcanological Survey of Indonesia).
