4.9-magnitude earthquake hits Uttarakhand's Chamoli, tremors felt in Delhi-NCR
Synopsis
Key Takeaways
An earthquake of magnitude 4.9 struck Uttarakhand's Chamoli district on Tuesday night, sending tremors across several parts of the state and into the Delhi-National Capital Region (NCR). The National Centre for Seismology (NCS) confirmed the quake at around 10:40 pm, with the epicentre recorded at approximately 13 km below the earth's surface.
Key Details of the Earthquake
According to the NCS, the earthquake struck at around 10:24 pm, with its epicentre located in Chamoli. Tremors were reported from multiple districts across Uttarakhand, including Bageshwar, Pithoragarh, Champawat, Rudraprayag, and Chamoli itself. Residents of Bhowali, Haldwani, Khatima, Rishikesh, Gopeshwar, and Badrinath also reportedly felt the shaking.
Tremors Reach Delhi-NCR
The seismic waves were strong enough to be noticed in parts of Delhi and the wider NCR. A resident of Safdarjung in South Delhi reportedly said they felt their couch move during the tremor. Before the official NCS confirmation, several residents had already taken to social media to ask whether others had experienced the shaking — an increasingly common pattern during Himalayan seismic events.
Magnitude vs Intensity: What Experts Say
Officials noted that a magnitude 4.9 earthquake is generally considered moderate and may be felt across a relatively wide area. However, the actual impact — in terms of shaking intensity and potential damage — depends on factors including the depth of the quake, local geological conditions, and the direction in which seismic energy propagates. Experts distinguished between magnitude, which measures energy released at the source, and intensity, which describes how strongly shaking is felt at a given location.
Uttarakhand's Seismic Vulnerability
Officials said the latest tremors once again underscore the seismic vulnerability of Uttarakhand and the broader Himalayan region, which sits in a high-risk earthquake zone due to the ongoing movement of tectonic plates. The region has a documented history of significant seismic activity, with past earthquakes — including the devastating 1991 Uttarkashi and 1999 Chamoli quakes — causing widespread destruction. No immediate reports of casualties or structural damage were available following Tuesday night's event.
What Happens Next
Authorities are monitoring the situation for aftershocks, which are common following moderate seismic events in tectonically active zones. Residents in the affected districts have been advised to remain alert and follow standard earthquake safety protocols.
