This sketch from a photo shows an aerial view of the Lokon-Empung volcanic complex from the north on August 23, 1982. The 400-m-wide, 150-m-deep crater of Empung volcano, which last erupted during the 18th century, is at the lower left. Almost all historical eruptions from Lokon-Empung have originated from Tompaluan crater, located in the saddle between Lokon and Empung. The word "air" in the bottom of the crater means water in Indonesian; a shallow lake periodically appears on the floor of the crater.
