Indonesia warns of flash flood risk in quake-hit Sigi Regency

Indonesia's National Disaster Management Agency (BNPB) has issued a stark warning about the potential for flash floods in the Sigi Regency, an area still reeling from a recent earthquake. BNPB head Lieutenant General Suharyanto urged local authorities to implement immediate mitigation measures.

Suharyanto's warning stems from drone surveillance that identified 24 landslide sites in the region's hills. Four of these locations show significant blockage due to landslide debris, creating a risk of natural dams forming. "Because of the rain, the water is held back, and it is feared that if the rainfall increases, there will be a risk of flash floods," Suharyanto stated, adding that authorities agreed to use pumps to clear the obstructions.

Because of the rain, the water is held back, and it is feared that if the rainfall increases, there will be a risk of flash floods. Today it has been agreed that it will be broken through using an alkon pump in the blocked part.

The agency and local government have agreed on emergency measures, including regular monitoring and clearing water flow paths with pumps to prevent the formation of dams that could break unexpectedly. This potential flood threat adds another layer of concern to the ongoing recovery efforts in Sigi Regency following the magnitude 6.7 earthquake on June 16, 2026. The quake not only damaged homes and public facilities but also triggered the landslides.

Despite the added risk, Suharyanto acknowledged the swift emergency response thus far. "From the coordination meeting just now, thank God, the handling has been very fast. Tents have been set up near residents' homes as a precaution against aftershocks," he said. He also visited affected villages, ensuring basic needs and temporary places of worship were being addressed. Sigi Regency has borne the brunt of the earthquake's impact, with three reported fatalities. The Meteorology, Climatology, and Geophysics Agency (BMKG) recorded 703 aftershocks, with 25 still felt by residents, prompting many to remain in temporary shelters. The Central Sulawesi Provincial Government has declared a seven-day emergency response status from June 17 to June 23, 2026, to expedite aid and disaster management.
