Sri Lanka was shaken near Kalmunai, Ampara District, Eastern Province, by an earthquake of magnitude 5.1 only 9 minutes ago, India's National Center for Seismology (NCS) reported.

The quake hit at a great depth of 366.2 km beneath the epicenter near Kalmunai, Ampara District, Eastern Province, Sri Lanka, early morning on Monday, December 11th, 2023, at 3:41 am local time. 

The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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.

Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kalmunai (pop. 100,200) located 51 km from the epicenter, Ampara (pop. 18,300) 67 km away, Batticaloa (pop. 86,700) 80 km away, and Eravur Town (pop. 23,000) 93 km away.
