Just before midnight on Tuesday, the Garhwal and Kumaon divisions of Uttarakhand experienced a sudden jolt at approximately 10:24 p.m.
The National Centre for Seismology recorded the event as a 4.9‑magnitude tremor on the Richter scale, locating the hypocenter in Chamoli district at a depth of roughly 13 km. The official time stamp reads 10:23:13 p.m. on 6 October.
Feeling the shaking were numerous towns, among them:
- Nainital
- Bageshwar
- Bhimtal
- Pithoragarh
- Champawat
- Haldwani
- Khatima
- Rudraprayag
- Rishikesh
- Gopeshwar
- Chamoli
- Badrinath
- Tharali
- Srinagar
- Pokhari
The tremor was not confined to Uttarakhand; several localities within the Delhi‑NCR region also reported perceptible shaking.
Chamoli Verified as the Earthquake’s Source
A subsequent review by the NCS reaffirmed Chamoli as the origin point, with coordinates of 30.103° N latitude and 79.561° E longitude. Despite the abrupt movement, early field assessments have not identified any major structural damage or casualties.
Persistent Seismic Risk in Uttarakhand
Situated along a highly active Himalayan fault line, Uttarakhand remains vulnerable to frequent seismic events. This ongoing risk highlights the need for earthquake‑resistant construction practices and comprehensive disaster‑preparedness strategies.
Recent updates to India’s seismic zoning map have placed Uttarakhand—and other Himalayan states—into the most sensitive zone, prompting stricter building regulations and heightened vigilance.
The 4.9‑magnitude tremor of Tuesday night serves as a timely reminder of the region’s geological fragility, even though it passed without causing significant harm.
