According to the regional meteorological office here, an aftershock measuring 5.7 on the Richter Scale shook Nepal at 5.04 pm.
The tremors which affected Bengal, triggered fresh panic among residents in Siliguri, Malda and elsewhere in north Bengal besides Kolkata.
The aftershocks come weeks after the devastating April 25 quake in the Himalayan nation.
The death toll due to the April 25 killer quake, measuring 7.9 on the Richter Scale, was 8,384.
While the country was barely recovering from the loss, a temblor measuring 7.3 on the Richter scale hit Nepal on Tuesday, with its epicentre not far from Mount Everest — the world’s highest peak at 8,848 metres. This left at least 117 dead.
