|The compound Ambang volcano is the westernmost of the active volcanoes on the northern arm of Sulawesi. The 1795-m-high stratovolcano rises 750 m above lake Danau. Several craters up to 400 m in diameter and five solfatara fields are located at the summit. Ambang's only known his... [more]|
|The massive Gunung Awu stratovolcano occupies the northern end of Great Sangihe Island, the largest of the Sangihe arc. Deep valleys that form passageways for lahars dissect the flanks of the 1320-m-high volcano, which was constructed within a 4.5-km-wide caldera. [more]|
|Banua Wuhu is a submarine volcano in the Sangihe Islands, Indonesia, 45 km south of Awu. The volcano rises more than 400 m from the sea floor and almost reaches the surface, forming a shallow shoal at 5 m depth. Banua Wuhu, during some of its eruptions, has created temporary isla... [more]|
|Karangetang (Api Siau) volcano is one of Indonesia's most active volcanoes. Located on the remote Api Siau Island north of N Sulawesi, it is notorious for building lava domes and producing dangerous pyroclastic flows. [more]|

|The twin volcanoes Lokon and Empung, rising about 800 m above the plain of Tondano, are among the most active volcanoes of Sulawesi.
Lokon, the higher of the two peaks (whose summits are only 2.2 km apart), has a flat, craterless top. The younger Empung volcano has a 400-... [more]
|The elongated Mahawu volcano lies immediately east of Lokon-Empung volcano. It 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 cont... [more]
|Ruang volcano is the southernmost volcano in the Sangihe Island arc, north of Sulawesi Island. The 4 x 5 km island volcano rises to 725 m across a narrow strait SW of the larger Tagulandang Island. The summit of Ruang volcano contains a crater partially filled by a lava dome in... [more]|
|Sempu is a statovolcano within a 3 km wide caldera containing an explosion crater (Kawah Masem maar) of 450x350 m diameter in the SW part of the caldera and contains a crater lake. There are no confirmed historical eruptions from Sempu.
Sulfur has been a site of sulfur ext... [more]
|The small Soputan stratovolcano on the southern rim of the Quaternary Tondano caldera on the northern arm of Sulawesi Island is one of Sulawesi's most active volcanoes. The youthful, largely unvegetated volcano rises to 1784 m and is located SW of Sempu volcano. It was construc... [more]|
|Tondano is a large, ca. 20 x 30 km wide lake-filled caldera in north Sulawesi and famous for its idyllic landscape. [more]|
