A magnitude 5.8 earthquake occurred on the evening of Monday, October 11, 2021 at 9:34 p.m. local time near Bitung, North Sulawesi, Indonesia, as reported by the Indonesian Meteorological and Climatological Agency. and geophysics.
According to preliminary data, the earthquake was located at a moderately shallow depth of 50 km. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
A second report was later released by the German Geoscience Research Center (GFZ), which listed it as a magnitude 5.7 earthquake. A third agency, the Euro-Mediterranean Seismological Center (EMSC), reported the same 5.7 magnitude earthquake.
Based on preliminary seismic data, the quake should not have caused significant damage, but was likely felt by many as a slight vibration in the epicenter area.
Weak tremors could have been felt in Bitung (pop. 137,400) located 126 km from the epicenter, and in Ternate (pop. 101,700) at 137 km.
