As the quake struck at around 1755 hours and lasted for about three seconds, people, with the devastations caused by last year's quake still fresh in memory, scampered out of their homes onto the roads and were reluctant to return fearing aftershocks.
Following the quake, power supply was switched off by the authorities for about 20 minutes before it was restored but telecom and Internet links were disrupted.
Today's tremor came on a day when people across Sikkim performed 'puja' not only to remember those who perished in last year's quake but also praying against a repeat of the same disaster.
