Delhi NCR Earthquake Tremors on 6 October 2026 Linked to Uttarakhand 4.9 Quake

Residents across Delhi-NCR felt noticeable shaking on the night of 6 October 2026. The tremors were caused by a magnitude 4.9 earthquake that struck Chamoli district in Uttarakhand. The National Centre for Seismology said the event occurred at 22:23:23 IST at a depth of 13 kilometres https://www.hindustantimes.com/india-news/earthquake-tremors-felt-in-delhi-ncr-magnitude-epicenter-101791305808884.html.

What happened in Chamoli and why Delhi-NCR felt it

The National Centre for Seismology reported the epicentre was located 50 km south of Joshimath, Uttarakhand. A shallow depth of 13 km allowed energy to propagate over long distance, which is why tremors were felt across Delhi-NCR on Tuesday. The NCS information was shared via a post on X and reported on 7 October 2026.

No casualties or structural damage in Delhi-NCR were reported in the provided sources. For verification, the NCS maintains official bulletins and social media updates that list time, magnitude, depth and coordinates for each event. Cross-checking the time stamp 22:23:23 IST on 6 October 2026 with the NCS feed confirms the origin.

Recent seismic cluster in early October 2026

The Delhi-NCR earthquake interest is part of a wider cluster of activity reported by NCS in the same week. The same bulletin that covered the Uttarakhand event also noted other recent shocks in different tectonic zones.

• Chamoli, Uttarakhand – 6 October 2026, 22:23:23 IST, M 4.9, depth 13 km
• Nagaon, Assam – 6 October 2026, 04:23:47 IST, M 4.5, depth 33 km
• Una, Himachal Pradesh – 4 October 2026, 23:48:35 IST, M 2.5, depth 9 km

The Assam event occurred at latitude 26.428 North and longitude 93.060 East, while the Himachal event was reported at Latitude 31.618 N and Longitude 76.301 E at a shallow depth of 9 kilometres. The variation in depth and location shows simultaneous activity in the Himalayan belt and the Northeast.

How to read the reports

Magnitude describes energy release, depth influences how widely shaking is felt, and epicentre location defines the surface point above the rupture. For Delhi-NCR, distance from the Uttarakhand epicentre and local soil conditions determine perception. Official data from NCS is the primary reference for origin time and parameters; USGS and other agencies provide independent global catalogues for cross-reference.
