complex volcano 1018 m / 3,340 ft
Lesser Sunda Islands, Indonesien, -8.53°S / 123.57°E
Eruption list: 2013, 1993, 1983, 1976 (?), 1973-74, 1952, 1951, 1950, 1949, 1948, 1941 (?), 1928, 1910, 1870
1993 submarine eruption
A submarine eruption took place at the Hobal vent at 50 m water depth, ca. 1 km SE off the coast of Iliwerung on 16 September 1993. The eruptions produced a water column 100 m high.
1983 submarine eruption
Explosions occurred 17 and 18 August from a submarine vent south of Iliwerung.
1979 landslide and deadly tsunami
In July 1979, a large landslide removed ca. 50 million m3 from the NW flank of Iliwerung volcano, a third of which reached the sea and caused a tsunami that killed hundreds of people.
1973-74 submarine eruptions, temporary islands
Submarine eruptions between December 1973 and August 1974 created 3 new temporary islands, which subsequently were eroded and disappeared.
1948 flank eruption
An eruption of Iliwerung volcano on 7 May 1948 produced a violent pyroclastic flow which reached the east coast and killed 300 cattle and destroying 100 farming sections. The eruption partly destroyed the lava dome. On 9 May, another eruption occurred at the lower eastern base of Iliwerung at about 140 m altitude and produced an ash plume of 4 km height, and opened a new 120 m wide crater, from which a viscous lava flow emerged, building up a new lava dome, called Iligripe. The new dome reached a height of 50 m by 11 May.
