BNPB spokesman Sutopo Purwo Nugroho said in a statement: "Based on our analysis of the natural disaster map, the quake's corresponding intensity was felt between III and IV on the Modified Mercalli Intensity (MMI) scale, or between light and moderate". No tsunami warning, fortunately, was declared.
An estimated 80,000 people have been displaced by the disaster, with many now living in tents outside their destroyed homes.
Foreign aid poured into the ravaged city of Palu where authorities believe 5,000 people could be missing and 200,000 survivors desperately need food, water and other life-saving supplies.
Agency spokesman Sutopo Purwo Nugroho said today prayers will be held, collectively, in Balaroa, Petobo and Jono Oge to "end the evacuation of bodies".
BMKG's Professor Dwikorita told Elshinta radio: "Intensity V could cause most of the items in a house to sway, with some of them falling onto the floor".
'I am sure Central Sulawesi will rise again, ' he said.
Foreign governments and global organisations should give a helping hand through aid, donations, volunteer work and humanitarian assistance.
After making a rare appeal for worldwide assistance, the country's aid agency says it now only needs tents, water treatment units, generators and transport, and that foreign aid workers can only be in the field with Indonesian partners.
