Mount Lamington is a stratovolcano located in Oro Province, southeastern Papua New Guinea. Rising above the forested plains near Popondetta, it forms part of the Pacific Ring of Fire — a geologically active zone known for its earthquakes and volcanoes. Though quiet today, Mount Lamington holds deep historical importance as the site of one of PNG’s deadliest natural disasters, the 1951 eruption. Its sudden and violent eruption reshaped the region, influencing not just the landscape but the course of local history and community development.
On 21 January 1951, Mount Lamington erupted without warning, killing over 4,000 people and devastating the surrounding region. Entire villages, including the then-provincial capital Higaturu, were destroyed by pyroclastic flows, ash, and toxic gases. Survivors were forced to flee through thick ash and scorched forest, with thousands left homeless.
The scale of the disaster prompted one of the earliest coordinated international relief efforts in Papua New Guinea. In the aftermath, Popondetta was established as the new administrative centre to support recovery and rebuild affected communities. Relief operations marked one of PNG’s first large-scale international humanitarian efforts, with aid arriving from Australia and other Commonwealth nations.
The eruption left a lasting legacy in PNG’s national memory. Today, stories of survival and loss are still passed down, and memorials in Popondetta honour those who died. The event also led to the formation of long-term volcano monitoring efforts across the country.
Mount Lamington is a classic stratovolcano, rising from the lowland rainforest of Oro Province in Papua New Guinea. It stands at around 1,680 metres above sea level, with a prominent ash cone and central lava dome formed from earlier eruptions. The volcano’s steep slopes are covered in dense vegetation, hiding much of its geological complexity until viewed from the air.
The volcano lies close to several major landmarks, including Girua Airport (Popondetta’s main air gateway) and the Kokoda Track, making it easily accessible for travellers and researchers alike. Its proximity to key transport routes and trekking destinations has made Mount Lamington one of the most widely recognised natural features in the region.
Mount Lamington is currently classified as dormant, but it remains under close observation by the Rabaul Volcanological Observatory. Seismic instruments and visual monitoring help detect any signs of renewed activity, ensuring early warnings can be issued if necessary.
Although the volcano has not erupted since 1951, it continues to shape life in the surrounding region. Many locals still share stories of the eruption through oral history, passing down memories of survival, loss, and community resilience.
Today, Mount Lamington stands as a quiet but powerful landmark. It serves as both a geological feature and a symbol of recovery for the people of Oro Province.
Travellers can explore the Mount Lamington region through cultural and historical experiences that highlight the volcano’s lasting impact. The area around Popondetta offers access to memorial sites, small museum exhibits, and community-run storytelling sessions that preserve the memory of the 1951 eruption.
While climbing Mount Lamington itself is not a common activity due to safety and cultural reasons, visitors often include the region as part of a broader trip to Oro Province, especially when trekking the nearby Kokoda Track.
Local communities maintain a strong connection to the mountain, viewing it as both a natural force and an important part of their identity. Respectful tourism supports these communities while offering visitors a deeper understanding of PNG’s history and resilience.
Mount Lamington is currently classified as a dormant volcano. It has not erupted since 1951 but is still monitored by the Rabaul Volcanological Observatory due to its potential to become active again.
While the volcano itself is not a common trekking destination, you can visit the surrounding region, including Popondetta. Here, you’ll find memorials, cultural sites, and historical information related to the eruption and local communities.
Mount Lamington stands at approximately 1,680 metres (5,512 feet) above sea level. Its height and forested slopes make it a striking feature in the Oro Province landscape.
Over 4,000 people lost their lives, and the provincial capital of Higaturu was destroyed. The disaster led to the relocation of the capital to Popondetta and remains one of PNG’s most tragic natural events.
Yes. Mount Lamington sits within the Pacific Ring of Fire, a major tectonic zone known for frequent earthquakes and volcanic activity, including many of PNG’s active volcanoes.
The surrounding rainforest is home to a variety of native bird species and tropical plants, contributing to the region’s ecological diversity.
