A series of minor earthquakes that have struck Johor since Sunday has highlighted the urgent need to intensify remapping and monitoring of active and ancient fault lines in Peninsular Malaysia.

Disaster Management Programme coordinator and senior lecturer at Elmu University, Rabieahtul Abu Bakar, said particular attention should be given to the Mersing Fault, as well as ancient fault lines such as Bukit Tinggi, Bentong–Raub and Kenyir.

She emphasised that a comprehensive study of these faults must incorporate advanced technologies, including 3D mapping and micro-seismic zonation, to determine the actual risk levels in affected areas.
