A 5.3-magnitude earthquake hit Indonesia's Sulawesi Island today. The epicenter of the earthquake occurred 103 km from Donggala Regency on the Island, at a depth of 34 km, the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) reported. Indonesia is regularly exposed to earthquakes due to its location on the Pacific Ring of Fire where many tectonic plates meet and cause frequent volcanic and seismic activity. Source: Oman News Agency
