The quake also caused damage to three churches, environmental activist Idris Tinulele said on Wednesday night quoting data from the Lore Utara sub-district, Palu district.
All the three churches are located in Wuasa village, capital of Lore Utara sub-district.
Idris said a team of the Meteorology, Climatology and Geophysics Agency (BMKG) has been stationed in the village since Wednesday morning to study the water coming out from the cracked soil in the wake of the 6.6-magnitude quake.
The agency has put up two special devices in the affected area to detect aftershocks, he said.
Idris, who is also bird researcher from Tadulako University (Untad) in Palu, capital of Central Sulawesi province, said several aftershocks were recorded throughout Wednesday.
Most of residents of Wuasa village chose to stay in tents put up in several places and yards of their houses following the May 29 earthquake, he said.
They preferred to stay outdoors for fear of aftershocks which may cause their houses to collapse, he said.
The Central Sulawesi Provincial Disaster Mitigation Board (BPBD) has distributed foods among earthquake victims in Lore Utara sub-district.(*)
