Rescue Operations Postponed Due to Ongoing Risks at Quarry Site

Rescue operations for two individuals feared buried under quarry rubble were postponed this afternoon. This decision was made due to the detection of continued earth movements in the affected area, compounded by unfavourable weather conditions.
Earth Movement Concerns Halt Rescues

The search for the two victims, identified as Kheow Loo Siew Soon, 49, and Itam Lasoh, 43, was halted because of ongoing geological instability. Authorities detected further earth movements at the quarry site, indicating that the area remained unsafe for rescue personnel to conduct operations.
Adverse Weather Conditions Exacerbate Risks

In addition to the detected earth movements, adverse weather conditions also contributed to the decision to postpone the rescue efforts. Heavy rainfall, which has been prevalent over the past two weeks, is cited as one of the contributing factors to the initial rockfall incident.
Quarry's Geological Vulnerability Highlighted

The rockfall occurred at a quarry in Keramat Pulai, an area known for active quarry operations. Experts noted that the limestone composition, rich in calcium carbonate, is susceptible to dissolution by water, leading to cavity formation. This geological characteristic weakens the rock structure and can result in slope surface failure, ultimately causing collapses.
Monitoring Continues for Safety Assurance

The Department of Mineral and Geoscience (JMG) has dispatched officers to monitor the situation at the quarry. Their role is to assess the stability of the rubble slope, ensuring that conditions are safe before search and rescue teams can resume their efforts.
