Earthquake – Twin Tremors Shake Sikkim Within an Hour

Earthquake –  Two back-to-back earthquakes struck parts of Sikkim on Thursday late morning, sending brief waves of concern across several districts. Authorities confirmed that while the tremors were clearly felt in some areas, there have been no immediate reports of casualties or structural damage.

First Tremor Recorded Near Yuksom

According to data released by the National Centre for Seismology, the first earthquake measured 4.6 on the Richter scale and occurred at 11:24 am. The epicentre was located approximately four kilometres northeast of Yuksom in Gyalshing district. Seismologists noted that the quake originated at a depth of about 10 kilometres beneath the surface.

Residents in and around Yuksom reported feeling the ground shake for a few seconds, prompting many to step outside as a precaution. However, district officials stated that the situation remained under control, and no emergency response was required immediately after the tremor.

Second Quake Follows in Mangan District

Less than an hour later, at 12:17 pm, a second earthquake measuring 3.5 magnitude was recorded. This tremor affected Mangan district, with its epicentre identified around 11 kilometres northwest of Gangtok. Similar to the earlier quake, it too occurred at a depth of 10 kilometres.

While the second tremor was milder in intensity, residents in parts of North Sikkim reported sensing light vibrations. Local authorities monitored the situation closely, but no incidents of property damage or injuries were reported following the second event.

No Immediate Damage Reported

Officials from the state administration confirmed that both earthquakes passed without causing harm to life or infrastructure. Routine assessments were carried out in vulnerable zones to ensure public safety. As of Thursday afternoon, no disruptions to essential services had been recorded.

Sikkim falls within a high seismic risk zone, making periodic tremors relatively common in the region. Experts say earthquakes of moderate magnitude can occur due to tectonic activity linked to the Himalayan belt. However, authorities continue to urge residents to remain prepared and follow safety guidelines during seismic events.

Monitoring and Preparedness Remain Key

The National Centre for Seismology continues to track seismic movements across the northeastern region. Disaster management teams remain on alert, though no emergency measures were activated after Thursday’s tremors.

Officials reiterated that the depth and moderate magnitude of the quakes likely helped limit their impact. They also encouraged citizens to stay informed through verified updates and avoid spreading unconfirmed information.

For now, life in Sikkim has returned to normal, with residents resuming daily activities shortly after the tremors subsided.
