The works ministry (KKR) has said that a total of 1,577 slopes along federal roads nationwide have been identified as high risk, Bernama reports.
These high-risk slopes are part of the 34,714 slopes monitored through the Slope Hazard and Risk Map developed by the public works department (JKR), which includes 26,722 slopes in Peninsular Malaysia, 4,178 slopes in Sabah, 3,633 slopes in Sarawak and 181 slopes in Labuan.
The ministry added that in the event of slope-related disasters, it will provide technical advice to the National Disaster Management Agency (NADMA) through JKR, while also supplying machinery, technical services, assessing damage to public infrastructure and implementing mitigation measures to reduce slope disaster risks.
“If a disaster involves water crossings or landslides, JKR will take several actions, including road closures, issuing warnings, providing alternative routes, constructing diversions and repairing affected roads. In addition, JKR, through its slope engineering branch, issues early warnings based on rainfall and slope movement data from the Early Warning System in high-risk areas,” the ministry said in a statement to the news outlet.
There are also 49 rain gauge stations nationwide – 37 in Peninsular Malaysia, nine in Sabah and three in Sarawak – to record rain data and issue early warnings when readings breach threshold levels at high-risk locations. “Three robotic total stations (RTS) and a global navigation satellite system (GNSS) have also been installed at Sections 44 and 46 of FT185 Jalan Simpang Pulai-Lojing-Gua Musang to monitor slope surface movement,” the ministry added.
In terms of spending, RM104.84 million has been used for slope repair works at 147 locations along federal roads in Peninsular Malaysia as of September this year. For 2025, RM118 million has been allocated to the ministry to support corrective slope repair and preventive maintenance.
“At the same time, routine maintenance is ongoing for very high- and high-risk slopes on the east coast, including Kelantan, Terengganu, Pahang and parts of Perak. In addition, the installation and maintenance of the Landslide Early Warning System and upgrades to the Integrated Slope Management System are underway,” the statement said.
The ministry will also deploy technologies such as tilt sensors, soil moisture sensors, inclinometers and piezometers at high-risk locations for more accurate, real-time data collection and enable precise preventive measures be put in place to reduce landslide incidents.
