According to BNPB, as of 21 June 2026 at 2300H UTC+7, the earthquake had resulted in 3 fatalities, 111 people with minor injuries, 17 people with serious injuries, and affected approximately 2.99K families (8.82K persons) across Central Sulawesi. Reported damages include approximately 2.66K houses (1.92K lightly damaged, 522 moderately damaged, and 212 severely damaged), as well as 90 places of worship, 31 educational facilities, 6 health facilities, 2 bridges, and 1 provincial road section connecting Palu–Sigi–Poso as well as 21 government office buildings and other public facilities.

BNPB continues to coordinate the emergency response with the provincial and district governments. Government of Central Sulawesi Province, as well as the governments of Sigi and Parigi Moutong districts, have declared a state of emergency response. BNPB has also mobilised relief items, including evacuation tents, family tents, food packages, mats, blankets, tarpaulins, and other essential relief supplies. Head of BNPB visited the affected areas and chaired a coordination meeting with relevant stakeholders, including local governments, TNI-Polri, BPBD, and other relevant agencies, to review the latest situation, emergency response priorities, and recovery planning. BNPB also plans to construct temporary shelters (HUNTARA) for households whose homes were severely damaged; establish temporary mosques and churches; support debris clearance, reopening of landslide-affected road access, river normalisation, and logistics operations; and coordinate rehabilitation and reconstruction efforts with relevant ministries and agencies. The AHA Centre continues to coordinate closely with BNPB and remains ready to provide assistance should the need arise.

HYDRO-METEO-CLIMATOLOGICAL:

For the past week, data from the ASEAN Specialised Meteorological Centre (ASMC) indicated medium to high seven-day average rainfall across Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Singapore, the Philippines, Thailand, and Viet Nam. As of 22 June at 1000H UTC+7, TC MEKKHALA, at typhoon category, had rapidly intensified while moving west-northwestward over the Philippine Sea. Although MEKKHALA is expected to remain far from the Philippine landmass, heavy rainfall and strong winds may still affect several areas of the Philippines (PAGASA). In addition, another tropical disturbance, INVEST 94W, located over the west Pacific Ocean, is forecast to move westward towards extreme northern Luzon, Philippines, before recurving towards Taiwan. 94W has a medium potential to develop into a significant tropical cyclone within the next 24 hours (PAGASA, JTWC).
