Assessing Singapore's Risk of Tsunamis

Despite Singapore's geographical position away from major tectonic plate boundaries, the city-state is not entirely immune to the threat of tsunamis.

A new study has indicated that there is a potential, albeit low, risk of Singapore being affected by a tsunami. This risk stems from the presence of 466 undersea volcanoes in the surrounding region, which, if they were to erupt, could lead to both ash fallout and/or tsunami waves reaching Singapore's shores.

Singapore's low-lying coastal areas and dense population make it crucial to remain vigilant and prepared for such natural disasters. While the probability of a tsunami hitting Singapore is low, the consequences could be severe, which would suggest that disaster preparedness and response plans would be for the best.


Ongoing monitoring of volcanic activity in the region would be essential to mitigate the potential impact of such events. Public awareness campaigns and regular emergency drills can also help ensure that both residents and authorities are prepared to act swiftly in the face of an emergency.

Although the chances of Singapore experiencing a tsunami are very slim, the recent study highlights the importance of continued vigilance and readiness to protect lives and property in the event of an unexpected undersea volcanic eruption.
