The Solomon Islands lie along the Pacific Ring of Fire, where tectonic collisions produce frequent volcanic activity that shapes islands, reefs and local livelihoods. Volcanic history here is patchy but important for navigation, fishing and hazard planning.
There are 3 Active Volcanoes in Solomon Islands, ranging from Kavachi to Tinakula. For each entry you’ll find below the data organized as: Location,Coordinates (lat, lon),Last confirmed eruption (year), so you can quickly compare where they are and when they last erupted — you’ll find below.
How recent are the eruptions and how reliable is the information?
Records for Solomon Islands volcanoes vary: some eruptions (like Kavachi) are well-documented by observations and satellite data, while others rely on historical reports or limited surveys. The “Last confirmed eruption (year)” column reflects the best-verified date available, but for remote vents that figure can change with new observations.
Are these volcanoes a hazard to people or shipping?
Yes — especially submarine and near-shore volcanoes such as Kavachi, which have produced explosive activity and floating pumice or steam plumes that can affect boats and aircraft. Local monitoring is limited, so mariners and nearby communities should heed notices from regional observatories and avoid reported eruption areas.
Active Volcanoes in Solomon Islands
| Name | Location | Coordinates (lat, lon) | Last confirmed eruption (year) |
|---|---|---|---|
| Tinakula | Temotu Province (Santa Cruz Islands) | -10.45, 167.03 | 2017 |
| Kavachi | Marine area south of Choiseul/Isabel Provinces | -8.90, 157.98 | 2019 |
| Savo | Savo Island, Central Province (near Guadalcanal) | -9.25, 159.90 | historic |
Images and Descriptions
Tinakula
A frequently active stratovolcano forming a small island in Temotu (Santa Cruz) Province. Eruptions recorded in recent decades, most recently 2017. Hazards include ash, lava flows and tsunamis; local monitoring is limited, so visitors and mariners should keep distance and heed warnings.
Kavachi
A very active submarine volcano that repeatedly builds ephemeral islands and generates explosive steam/ash bursts. Hazards include violent surface explosions, hot water and tsunamis; unsafe for visitors. Monitoring is mainly by satellite, ship reports and occasional surveys.
Savo
Small volcanic cone forming Savo Island just north of Guadalcanal. Known for historic eruptions and persistent fumaroles; last confirmed activity is historic. Hazards include ash, pyroclastic flows and toxic gases. Monitoring is limited—residents and visitors should follow local advisories.
