Why in news?
Kavachi volcano, a shallow submarine volcano in the South Pacific Ocean near the Solomon Islands, has recently gained attention for rare footage showing sharks thriving inside its active crater. This discovery challenges scientific understanding of marine life in extreme volcanic conditions.
Location & Geographical Context
- Situated in the South Pacific Ocean, south of Vangunu Island in the Solomon Islands.
- Lies on the Pacific Ring of Fire, a tectonically active zone with frequent earthquakes and volcanic activity.
- Classified as a shallow submarine volcano (underwater volcano close to the surface).
Volcanic Activity
- Highly active: Known for regular but unpredictable eruptions.
- Island-building events: Sometimes eruptions create temporary islands that later erode back into the sea.
- One of the world’s few visible undersea volcanoes.
Unique Ecological Significance
- Scientists discovered sharks and other marine life inside the crater, challenging assumptions about survival in extreme volcanic environments.
- This phenomenon is called “sharkcano” in popular science reporting.
