JAKARTA, Indonesia -- A strong earthquake of 6.6 has rocked a north Indonesian island. No tsunami warning has been issued and there are no immediate reports of damages or casualties.
The U.S. Geological Survey says Saturday's quake struck 56 kilometres south-east of Palu city on Sulawesi Island at a depth of 20.2 kilometres. It hit at 17:41 local time (0941 GMT).
Indonesia is prone to earthquakes because it is in the Pacific Ring of Fire, an arc of volcanos and fault lines encircling the Pacific Basin.
