There are no Holocene eruptions known for Lihir. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

Lihir Island, the largest of an island group north of New Ireland, is a Pliocene-to-Holocene volcanic complex of several overlapping basaltic stratovolcanoes. The youngest volcano, Luise, contains an elliptical, 5.5-km-wide caldera that is breached by the sea on the NE side as a result of edifice collapse about 0.4 million years ago, forming Luise Harbor. The flanks of the volcano are only moderately dissected. The steep-sided caldera wall rises to 700 m above sea level. A central lava plug is strongly hydrothermally altered and displays extensive thermal activity along its margins. Thermal activity includes boiling hot springs, mud pools, and sulfur-encrusted low-temperature fumaroles. The Ladolam hydrothermal deposit hosts one of the youngest and largest gold deposits in the world, which is now being extracted by open-pit mining. The near-surface, epithermal gold deposition extends to about 400 m below sea level over an area of about 2 sq km.
