성층화산 · Indonesia · 1299m

Mahawu volcano, located immediately to the east of Lokon-Empung volcano, contains a 450-m-wide, 140-m-deep summit crater. Active fumaroles are seen in this 1991 photo of the north end of the crater, which sometimes contains a crater lake. Small-to-moderate explosive eruptions have been recorded at 1331-m-high Mahawu volcano since the 18th century.

지질학적 요약

The elongated Mahawu volcano immediately east of Lokon-Empung volcano is the northernmost of a series of young volcanoes along a SSW-NNE line near the margin of the Quaternary Tondano caldera. Mahawu is capped by a 180-m-wide, 140-m-deep crater that sometimes contains a small crater lake, and has two pyroclastic cones on its N flank. Historical activity has been restricted to occasional small explosive eruptions recorded since 1789. In 1994 fumaroles, mudpots, and small geysers were observed along the shores of a greenish-colored crater lake.
