An earthquake of slight intensity shook border areas of West Bengal and Orissa on Saturday evening, the meteorological department in New Delhi said.
The quake, measuring 4.4 on the Richter scale, was felt at 1806 IST, a department release said.
The epicentre of the quake was at 21.7 degree North latitude and 87.3 degree East longitude on the West Bengal-Orissa border, it said.
It was not yet known whether any damage had been caused by the tremor and if it was related to the over 80 aftershocks that have rocked Andaman and Nicobar Islands and its surroundings since last Sunday's massive quake off the coast of Indonesia, which triggered tsunami waves.
