The National Centre for Seismology placed the epicenter at 30.10°N, 79.56°E in Uttarakhand, at a focal depth of 13 kilometers, with a magnitude of 4.9. Tremors were felt across Delhi-NCR high-rise towers in Noida, Ghaziabad, and parts of Haryana. Authorities confirmed zero casualties and no structural damage based on initial reports. NDRF teams were placed on standby as a precaution.
Where was the epicenter of today’s earthquake felt in Delhi? The NCS placed it at coordinates 30.10°N, 79.56°E in Uttarakhand at a depth of 13 kilometers, sending shockwaves across western Uttar Pradesh, Haryana, and the National Capital Region.
For residents across Uttarakhand and Delhi-NCR, the M4.9 quake caused zero reported structural collapses or casualties based on current information. Aftershocks are possible following the event; residents should follow official advisories from the NCS and district authorities. High-rise dwellers in NCR experienced amplified swaying due to how alluvial ground responds to seismic waves at distance. Do not act on unverified social media claims about larger follow-up events.
Uttarakhand sits within the Main Central Thrust of the Central Himalaya—one of the most seismically active fault systems in South Asia, classified under Seismic Zone V, India’s highest vulnerability category. The Delhi-NCR region lies in Seismic Zone IV. The deep alluvial soil of the Indo-Gangetic basin amplifies long-period seismic waves selectively—this is why high-rise towers in Noida and Ghaziabad can sway noticeably during Uttarakhand earthquakes while ground-level structures nearby feel less movement.

Follow NCS aftershock bulletins and official Uttarakhand district administration updates, not social media chains, for verified impact assessments. The National Disaster Management Authority advises residents to verify that building stairwells and fire exits remain unobstructed in the window following a tremor.
