Sundoro Volcano - John Seach

Hundreds of hills on the NE side of the mountain are remnants of ancient landslides and lahars.

Eruptions have historically produced ash plumes rising from the summit which were visible for tens of kilometers. However, no record of volcanic ash on the ground has been found, indicating ash was too thin to be preserved.
