A magnitude 4.4 earthquake near Sofifi, Kota Tidore Kepulauan, North Maluku, Indonesia, was reported only 10 minutes ago by Indonesia's Meteorology, Climatology, and Geophysical Agency, considered the main national agency that monitors seismic activity in Indonesia. The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Tuesday, October 19th, 2021, at 1:29 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.4 as well.
