Landslide Warning: Infrastructure Potentially Affected in March 2023

A landslide in Natuna Regency, Riau Islands, has claimed many lives. The latest data released by the National Disaster Management Agency (BNPB) on Friday (March 10, 2023) reports 36 fatalities, 30 of whom have been identified. Eighteen people are still missing, and 1,216 people are taking refuge at four locations.

BNPB Head Lieutenant General TNI Suharyanto stated that since the disaster struck on Monday (March 6, 2023), emergency operations have yielded results, although roads blocked by landslides are not yet fully open due to frequent rain.

The Ministry of Public Works and Public Housing (PUPR) has dispatched seven excavators. PUPR Minister Basuki Hadimuldjono, who also visited the affected area, aims to reopen the road within two days.

"The landslide-blocked road is approximately 300 meters long. But since last night, seven excavators have been working, and we aim to have it fully open within two days," said Basuki in a written statement received by *Databoks*, Friday (March 12, 2023).

Basuki ensured that the government will build supporting infrastructure, including roads, bridges, places of worship, and water facilities for basic needs.

"We will rebuild the roads, bridges, water supply, and mosques for the new community," said Basuki.

Besides the road paralyzed by the landslide, what other infrastructure was affected by this natural disaster?

PUPR previously recorded infrastructure potentially impacted by high-ground movement or landslides in March 2023. A total of 1,033 infrastructures were deemed 'fragile' against this disaster.

First, as in Natuna, national roads are prone to being buried by landslides and other impacts, totaling 310 locations or points.

Second, reservoirs (embung) with 126 locations. Third, sabodams (water or lava control structures) predicted to be affected by landslides, numbering 108 locations.

Fourth, bridges, with 107 locations. Fifth, SPAM (drinking water supply systems) with 68 locations.

In its report, PUPR stated that the prediction of potential landslide areas was compiled based on the overlay of the landslide vulnerability zone map with the monthly rainfall forecast map obtained from the Ministry of Energy and Mineral Resources (ESDM). This also serves as a warning to residents regarding nearby infrastructure.

"Therefore, this information is needed to anticipate the worst-case scenario for PUPR infrastructure," wrote PUPR.

The following is a complete list of infrastructure potentially affected by landslides in March 2023:

* National roads: 310 points
