Risk Assessment of Earthquake Occurrences in Areas Close to Singapore

Mr Alex Yeo asked the Minister for Sustainability and the Environment (a) whether the recent Segamat earthquake in Johor is the closest in distance historically to Singapore; (b) whether the Ministry has done a review on the risk assessment of future similar occurrences in areas close to or within Singapore; and (c) if so, what is the result of the review.

Singapore is considered to have a low earthquake risk, as we are geologically stable and are not on any known major active fault lines. The earthquake on 3 September 2025 near Segamat was one of the three closest documented earthquakes to Singapore, with an epicentre about 120 kilometres northwest of Singapore. The Meteorological Service Singapore (MSS) will continue to closely track regional seismic developments.

The Building and Construction Authority maintains a building safety framework to ensure infrastructure resilience in Singapore and will continue to review and update it based on MSS's monitoring of regional seismic activity.

The Government will also continue to work with research institutes, such as Earth Observatory of Singapore, to deepen our understanding of regional seismic occurrences and update our risk assessments if necessary.
