Moderate magnitude 4.3 earthquake 64 km southeast of Aizawl, India

4.3 quake 15 Sep 6:59 pm (GMT +5:30)
4.3 quake 15 Sep 6:59 pm (GMT +5:30)
Just 18 minutes ago, a 4.3-magnitude earthquake struck near Aizawl, Aizawl district, Mizoram, India. The tremor was recorded early evening on Wednesday, September 15th, 2021, at 6:29 pm local time, at a shallow depth of 10 km below the surface.
The event was filed by India's National Center for Seismology (NCS), the first seismological agency to report it.
Our monitoring service identified a second report from Thailand's Earthquake Observation Division (TMD) which listed the quake at magnitude 4.3 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.3.
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 Khawhai (pop. 2,500) located 25 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include North Vanlaiphai (pop. 3,500) located 51 km from the epicenter, Serchhip (pop. 20,200) 54 km away, Thenzawl (pop. 6,000) 62 km away, Aizawl (pop. 265,300) 64 km away, Sāitlaw (pop. 11,000) 90 km away, Lunglei (pop. 52,700) 92 km away, and Churāchāndpur (pop. 47,800) 97 km away.
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.
