Just 15 minutes ago, a 4.4-magnitude earthquake struck near Ternate, North Maluku, Indonesia. The tremor was recorded in the morning on Sunday 27 December 2020 at 8:36 am local time, at an intermediate to considerable depth of 151 km below the surface.
The event was filed by Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), the first seismological agency to report it.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.4 as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tobelo (pop. 10,000) located 85 km from the epicenter. In Ternate (pop. 101,700, 85 km away), and Sofifi (pop. 36,200, 96 km away), the quake was probably not felt.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
