Kavachi volcano, located in the Solomon Islands, is a remarkable example of a shallow submarine volcano. Situated on the complex tectonic boundary between the converging Pacific and Australian plates, Kavachi displays frequent phreatomagmatic eruptive activity driven by the interaction of seawater with rising magma. These eruptions are characterized by the ejection of tephra, steam, and volcanic gases, often accompanied by the formation of short-lived surtseyan islands.

Kavachi’s Eruptive History

Year Eruptive Activity
1939 First recorded eruption, details about the size and style remain limited.
1950s-1980s Frequent eruptive activity, including steam-driven explosions, ejection of ash and volcanic debris, formation of short-lived islands that often reached a few meters above sea level.
1991 Large eruptions with reports of ash columns rising hundreds of meters into the air.
2000-2003 Increased activity characterized by strong explosions, discolored water, and the formation of a substantial island measuring up to 15 meters in height before erosion.
2004 Explosive eruptions leading to the creation of another short-lived island.
2007 Large eruptions with ash plumes and possible island formation.
2014 Large eruptions generating ash-rich plumes and incandescent bombs.
2021-2023 Satellite imagery reveals ongoing activity, primarily evidenced by extensive areas of discolored water surrounding the volcano due to gas and thermal emissions.
