According to Asia pacific Reuters agency a shallow and strong earthquake of magnitude 6.1 struck the Myanmar-India border region early on Friday, but there were no immediate reports of damage.

According to India’s National Center for Seismology, the quake was at depth of 12 km, and was about 140 km away of Aizawl in northeastern India.

It was felt in Chittagong in Bangladesh and as far away as east Indian city of Kolkata, some 280 miles (450.62 km) from Aizawl, according to witness accounts posted on European-Mediterranean Seismological Centre’s (EMSC) website and by users on Twitter.

“Very strong,” one such witness posted on EMSC from Chittagong, which is about 184 km (115 miles) west of the quake’s epicentre.

Tremors were felt across states in northeastern India and major cities in Bangladesh, according to EMSC and India’s earthquake monitoring agency.

EMSC pegged the temblor’s magnitude at 5.8, after having earlier given it a magnitude of 6.0.

People, who felt the effects of the earthquake in parts of India, including Kolkata, Tripura, Manipur, Mizoram and Assam besides Bangladesh, took to Twitter to report the tremor. 

The epicentre of the earthquake lay 183km east of Chittagong in Bangladesh. According to the National Center for Seismology, the quake occured at 5.15am, at a depth of 35km.

There were also reports of a second earthquake at 5.53am. 

The northeastern region of the country sits on a high seismic zone, making earthquakes frequent in the area. 

An earthquake of 6.4 magnitude had shaken Assam and parts of the region on April 28 earlier this year.

According to the Euro-Mediterranean Seismological Centre (EMSC), a strong and shallow earthquake of magnitude 6.0 struck the Myanmar-India border region around 5.15am on Friday.
