Indonesia's Reefs Blasted Hourly: A Silent Crisis
14 Aug
Summary
- Explosions occur hourly in Indonesian archipelago due to bomb fishing.
- Acoustic monitoring and AI revealed 3567 explosions over 483 days.
- Tackling illegal supply chains is key to curbing destructive practice.

An alarming rate of underwater explosions, averaging over 23 per day, has been detected in Indonesia's Spermonde Archipelago. Researchers deployed an acoustic monitoring system for 483 days between May 2023 and September 2024, with AI analysis revealing 3567 explosions within a 17-kilometre radius.
This intense activity is attributed to bomb fishing, a practice that devastates vital coral reef ecosystems and marine biodiversity. The sound of these explosions is profoundly disruptive, even being felt physically by divers. The illegal supply chain for explosives, often involving fertilizers and detonators, is a significant factor enabling this destruction.
Experts suggest that effectively combating bomb fishing requires a multi-faceted approach. Targeting the illicit supply chain that provides materials for explosives is seen as a primary strategy. Furthermore, retraining local communities in sustainable tourism and reef restoration offers a viable path towards conservation and economic alternatives.
