In the early hours of February 17, 2025, a 4.0-magnitude earthquake shook Delhi-NCR, catching residents off guard with its unexpectedly strong tremors. Although considered moderate in magnitude, the quake’s intensity was amplified due to its shallow depth of just 5 km and its epicentre near Dhaula Kuan, a densely populated area in South Delhi. This proximity meant that seismic waves travelled rapidly, shaking buildings and prompting people to rush out of their homes in panic.
Meanwhile, Prime Minister Narendra Modi, in his message on social platform X, wrote, “Tremors were felt in Delhi and nearby areas. Urging everyone to stay calm and follow safety precautions, staying alert for possible aftershocks. Authorities are keeping a close watch on the situation.”
Why Did It Feel So Strong?
Experts suggest that the reason for the strong tremors lies in the shallow depth of the earthquake. Shallow earthquakes tend to cause more surface shaking compared to deeper ones, even at lower magnitudes. Additionally, Delhi’s geological composition, predominantly alluvial soil, amplifies seismic waves, making the tremors feel more intense.
Delhi’s Seismic Vulnerability
Delhi is located in Seismic Zone IV, a high-risk area prone to significant earthquakes. Its proximity to active fault lines, including the Delhi-Hardwar Ridge and the Mahendragarh-Dehradun Fault, makes it particularly vulnerable. Urban density and rapid infrastructure development without adequate earthquake-resistant measures further increase the city’s risk.
Recent Developments and Public Reaction
Following the earthquake, no significant damage or casualties were reported. However, the incident served as a stark reminder of Delhi’s seismic vulnerability. Social media was flooded with videos showing ceiling fans shaking and people evacuating buildings in areas like Noida, Greater Noida, and Ghaziabad. The National Center for Seismology (NCS) continues to monitor seismic activity in the region, and authorities have urged citizens to stay alert and be prepared for aftershocks.
