Visual Characteristics

Mount Ulawun is a conical volcano with steep slopes. Its summit is characterized by a crater that emits steam and volcanic gases. The volcano is primarily composed of basaltic and andesitic lava flows. Vegetation covers the lower slopes, transitioning to barren volcanic rock and ash near the summit.

Parking is informal and available at the trailhead, with capacity for a limited number of vehicles.

Historical & Ecological Origin

Mount Ulawun is part of the Bismarck Volcanic Arc, formed by the subduction of the Solomon Sea Plate beneath the Pacific Plate. It is a stratovolcano, built up over thousands of years by successive eruptions of lava and ash. The volcano's eruptive history dates back at least 30,000 years, with significant eruptions recorded in historical times, including major events in 1700, 1878, 1915, 1937, 1967, 1970, 1973, 1980, 1982, 1984, 1985, 1989, 1990, 1992, 1995, 1997, 1998, 2000, 2001, 2003, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, and 2023.
