Sirung

Country: Indonesia
Subregion Name: Lesser Sunda Islands (Indonesia)
Volcano Number: 0604-27=
Volcano Type: Complex volcano
Volcano Status: Historical
Last Known Eruption: 1970 
Summit Elevation: 862 m 2,828 feet
Latitude: 8.508°S 8°30’30″S
Longitude: 124.13°E 124°8’0″E
Sirung volcano is located at the NE end of a 14-km-long line of volcanic centers that form a peninsula at the southern end of Pantar Island. The low, 862-m-high volcano is truncated by a 2-km-wide caldera whose floor often contains one or more small lakes. Much of the volcano is constructed of basaltic lava flows, and the Gunung Sirung lava dome forms the high point on the caldera’s western rim. A number of phreatic eruptions have occurred from vents within the caldera during the 20th century. Forested Gunung Topaki, the 1390-m high point of the volcanic chain, lies at the SW end and contains a symmetrical summit crater.

Batu-Tara

Country: Indonesia
Subregion Name: Lesser Sunda Islands (Indonesia)
Volcano Number: 0604-26=
Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 2010 
Summit Elevation: 748 m 2,454 feet
Latitude: 7.792°S 7°47’30″S
Longitude: 123.579°E 123°34’45″E
The small isolated island of Batu Tara in the Flores Sea about 50 km north of Lembata (fomerly Lomblen) Island contains a scarp on the eastern side similar to the Sciara del Fuoco of Italy’s Stromboli volcano. Vegetation covers the flanks of Batu Tara to within 50 m of the 748-m-high summit. Batu Tara lies north of the main volcanic arc and is noted for its potassic leucite-bearing basanitic and tephritic rocks. The first historical eruption from Batu Tara, during 1847-52, produced explosions and a lava flow.

Summit Elevation: 1018 m 3,340 feet
Latitude: 8.53°S 8°32’0″S
Longitude: 123.57°E 123°34’0″E
Constructed on the southern rim of the Lerek caldera, Iliwerung forms a prominent south-facing peninsula on Lembata (formerly Lomblen) Island. Craters and lava domes have formed along N-S and NW-SE lines on the complex volcano; during historical time vents from the summit to the submarine SE flank have been active. The Iliwerung summit lava dome was formed during an eruption in 1870. In 1948 Iligripe lava dome grew on the eastern flank at 120 m altitude. Beginning in 1973-74, when three ephemeral islands were formed, submarine eruptions began on the lower SE flank at a vent named Hobal; several other eruptions took place from this vent before the end of the century.

Anchoring the eastern end of an elongated peninsula that is connected to Lembata (formerly Lomblen) Island by a narrow isthmus and extends northward into the Flores Sea, Lewotolo rises to 1423 m. Lewotolo is a symmetrical stratovolcano as viewed from the north and east. A small cone with a 130-m-wide crater constructed at the SE side of a larger crater forms the volcano’s high point. Many lava flows have reached the coastline. Historical eruptions, recorded since 1660, have consisted of explosive activity from the summit crater.

Iliboleng stratovolcano was constructed at the SE end of Adonara Island across a narrow strait from Lomblen Island. The volcano is capped by multiple, partially overlapping summit craters. Lava flows modify its profile, and a cone low on the SE flank, Balile, has also produced lava flows. Historical eruptions, first recorded in 1885, have consisted of moderate explosive activity, with lava flows accompanying only the 1888 eruption.

Summit Elevation: 1117 m 3,665 feet
Latitude: 8.358°S 8°21’30″S
Longitude: 122.842°E 122°50’30″E
Leroboleng volcano, also known as Lereboleng or Lewono, lies at the eastern end of a 4.5-km-long, WSW-ESE-trending chain of three volcanoes straddling a narrow peninsula in NE Flores Island. The summit of Gunung Leroboleng contains 29 small fissure-controlled craters, two containing lakes. A small lava dome occupies one of the craters. Most of the craters originated along three N-S-trending fissures immediately east of the summit of the volcano. The largest crater, 250-m-wide Ili Gelimun, is located SSE of the summit and fed lava flows from a lower south-flank vent. Explosive eruptions were reported from Burak crater during the 19th century.
