JAKARTA - The BNPB Operations Control Center identified several hydrometeorological disasters, such as floods and landslides, in several regions of Indonesia towards the end of the fourth week of July 2020. One of them hit a number of villages in Bolaang Mongondow Regency, North Sulawesi.
The BPBD of Bolaang Mongondow Regency reported that floods and landslides occurred in three sub-districts. The disaster occurred on Saturday, July 25 at 03.30 local time. The three affected sub-districts are West Dumoga, Central Dumoga and North Dumoga, while the number of affected villages in the three sub-districts is ten.
The affected villages in the following three sub-districts are Doloduo, Doloduo III, Ikhwan, Wangga Baru and Wangga Baru Villages (West Dumoga Subdistrict), Kosio Induk and Kosio Barat Villages (Central Dumoga), Dondomon Villages, North Dondomon and South Dondomon (Dumoga North).
"A total of 301 families or 905 people fled to relatives' homes, while 259 houses were affected. Another impact is the road connecting Doloduo III Village - Toraut Amblas Village and can only be passed by two-wheeled vehicles," said Head of the BNPB Disaster Data, Information and Communication Center Raditya Jati in official statement, Saturday, July 25.
There are ten landslide points on the Doloduo-Molibagu road section which connects Bolaang Mongodow and Bolaang Selatan districts. Besides the connecting road, the Kosio bridge that connects Central Dumoga Subdistricts and West Dumoga Districts collapsed for 7 meters.
After the event, the Regent of Bolaang Mongondow established an emergency response status for 14 days, starting from 25 July to 7 August 2020. BPBD and other related agencies have made emergency response efforts, such as rapid assessments, evacuation of victims and coordination with related agencies. Heavy equipment and emergency bridges have been deployed to open access connecting Doloduo III and Toraut Villages.
One of the triggers of this incident was rain with moderate to high intensity that fell in the Bolaang Mongodow area. The rain caused the Ongkag Dumoga River discharge and the Toraut Dam water discharge to overflow with a water level of 50–200 cm. Conditions at 17.30 local time showed cloudy weather and thick clouds.
