Tremors were felt across the Kalimpong region, including Darjeeling, around midnight, with two earthquakes occurring within a short span of time. At the same time, a series of tremors was recorded in neighbouring Sikkim, triggering panic among residents.
The first tremor struck at 1:09 am on Thursday (early Friday as per local time) with a magnitude of 4.3 on the Richter scale. Just six minutes later, at around 1:15 am, a second tremor was felt. According to the National Centre for Seismology, the second quake measured 3.1 on the Richter scale.

Apart from Kalimpong, the tremors were also felt in Siliguri, Darjeeling and several other parts of North Bengal, as well as across different regions of Sikkim. The National Centre for Seismology said the epicentre of the initial tremors was in Gyalshing, Sikkim, with both earthquakes originating at a depth of about 10 kilometres.
Seismic activity continued in Sikkim between 1:15 am and 5:00 am, during which at least 10 tremors were recorded. All of them were reported to be mild, with magnitudes ranging between 2 and 4 on the Richter scale. The epicentres of these tremors were located in the Mangan and Namchi areas of Sikkim, at depths of 5 to 10 kilometres.

An earthquake was also reported in Gangtok, the capital of Sikkim, at around 1:15 am. This tremor had a magnitude of 3.1 on the Richter scale and originated about 10 kilometres below the surface.
Meanwhile, tremors were also felt in parts of Tibet. The National Centre for Seismology reported a 4.5-magnitude earthquake there at around 2:30 am, with its source located 25 kilometres underground.
No major damage was reported following the tremors. However, geologists have expressed concern, warning that such a cluster of consecutive earthquakes could signal increased seismic risk in the coming days.
