5.1 quake 8 Feb 10:34 pm (GMT +10)
An earthquake of magnitude 5.1 occurred only 26 minutes ago 21 km southeast of Madang, Papua New Guinea, the United States Geological Survey reported.
The quake hit at a moderately shallow depth of 64.4 km beneath the epicenter near Madang, Madang Province, Papua New Guinea, late at night on Monday 8 February 2021 at 10:34 pm 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 5.1 as well.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Madang (pop. 27,400) located 21 km from the epicenter, Goroka (pop. 18,500) 99 km away, and Kainantu (pop. 8,500) 103 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kundiawa (pop. 9,400) located 127 km from the epicenter.
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.
