Moderate 4.3 quake hits near Joshīmath, Chamoli, Uttarakhand, India

4.3 quake 24 May 12:31 am (GMT +5:30)
4.3 quake 24 May 12:31 am (GMT +5:30)
India's National Center for Seismology (NCS) reported a magnitude 4.3 quake in India near Joshīmath, Chamoli, Uttarakhand, only 10 minutes ago. The earthquake hit after midnight on Monday 24 May 2021 at 12:01 am local time at a shallow depth of 22.1 km. 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.
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 Kedārnāth (pop. 510) located 32 km from the epicenter, and Joshīmath (pop. 13,900) 44 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Uttarkāshi (pop. 17,100) located 87 km from the epicenter, Srinagar Garhwal (pop. 20,200) 92 km away, Pauri (pop. 26,500) 99 km away, and Tehri (pop. 27,600) 99 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.
