Indian seismologists said the quake measured 5.2 on the Richter scale, India Today reported. The U.S. Geological Survey put the magnitude at 5.5 and said the quake hit just after 7 a.m. local time.
No casualties were reported and no details were available on damage. Quakes of that magnitude can cause significant damage to poorly constructed buildings.
"The exact epicenter of the quake was on the India-Bangladesh border with western Tripura. The tremor lasted for about four to five seconds," a spokesman for the Regional Seismological Center told Indo-Asian News Service.
Seismologists say the region ranks sixth in the world for earthquakes. In 1897, a quake of 8.7 magnitude killed 1,600 people.
