The Palu Meteorological, Climatology and Geophysics Agency (BMKG) in Central Sulawesi says the region has been rocked by around 30 earthquakes daily over the last four months. 

The numerous daily quakes are caused by shifts in the Palukoro fault, which extends from Poso to the waters of Tolitoli regency and branches off to the Matano fault in South Sulawesi. 

"The magnitudes of the tremors vary. Some were undetectable while others could be felt by in the region," Cahyo Nugraha, head of the BMKG’s geophysics department, told The Jakarta Post on Wednesday. 

A 5.2-magnitude earthquake destroyed houses, churches, mosques and schools in North Lore district, Poso, Central Sulawesi, last year.  

Tadulako University seismologist Abdullah said because it sat on top of one of the most active faults in the country, Palu in Central Sulawesi was considered to be among areas that were most prone to earthquakes and tsunamis in eastern Indonesia. 

The first tsunami in the area was recorded in 1927 when a 15-meter wave slammed into the city, killing 15 people and injuring 50.  

A 1938 tsunami killed 16 people and destroyed piers and a lighthouse on the Parigi shore, while another tsunami in the city of Tambu in 1968 followed a 6.0-magnitude quake. (ris)
