Iliwerung

복합화산 · Indonesia · 583m

A lava dome, formed during the first historical eruption of Iliwerung volcano in 1870, occupies the summit crater of the volcano, seen here in 1979 from the rim of Ado Wajung crater. Iliwerung forms one of the south-facing peninsulas on Lembata (formerly Lomblen) Island, and has a series of lava domes and craters along N-S and NW-SE lines. Many of these vents, including submarine vents offshore, have erupted in historical time.

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; activity has been observed at vents from the summit to the submarine SE flank. The summit lava dome was formed during an eruption in 1870. In 1948 the Iligripe lava dome grew on the E flank at 120 m elevation. Beginning in 1973-74, when three ephemeral islands were formed, submarine eruptions began on the lower ESE flank at a vent named Hobal; several other eruptions have since taken place at this vent.
