New Delhi: Tremors were once again felt across Delhi and the National Capital Region (NCR) on Friday evening, marking the second consecutive day of seismic activity in the region.
The earthquake, which had its epicentre in Haryana’s Jhajjar district, occurred at 7:49 PM and registered a magnitude of 3.7 on the Richter scale, according to the National Center for Seismology (NCS).
The quake struck at a shallow depth of 10 kilometres beneath the surface, making the tremors perceptible across several parts of the NCR.
Although no casualties or damage were reported, the event caused momentary panic among residents, many of whom took to social media to share their experiences.
This latest tremor follows a stronger earthquake that occurred just a day earlier, on Thursday morning. That quake, recorded at 9:04 AM, also originated in Jhajjar and measured 4.4 in magnitude.
The back-to-back quakes have heightened public concern, especially in areas like Delhi, Gurugram, Noida, and Ghaziabad, where tremors were distinctly felt.
Aftershocks and Tectonic Stress
Seismologists note that aftershocks are a common occurrence following a primary earthquake. These subsequent tremors, typically lower in magnitude, signify the gradual release of accumulated tectonic stress.
Far from being alarming, experts consider this a normal part of the earth’s adjustment process, which often reduces the likelihood of a more severe quake in the near future.
The frequency of tremors in this area is a result of complex geological factors. The Delhi-NCR and its neighbouring districts such as Jhajjar, Rohtak, and Gurugram sit atop a web of active fault lines.
Among these are the Mahendragarh-Dehradun Fault (MDF), Delhi-Haridwar Ridge (DHR), Delhi-Sargodha Ridge (DSR), Delhi-Moradabad Fault, Sohna Fault, Mathura Fault, and the Reverse Fault (F1).
Mahendragarh-Dehradun Fault: A Key Player
One of the most significant fault systems in the region is the Mahendragarh-Dehradun Fault. This geological feature links the stable Indian tectonic plate to the more volatile Himalayan Frontal Thrust.
Stretching from Mahendragarh in Haryana to Dehradun in Uttarakhand, the MDF traverses several densely populated zones, including large portions of Delhi and its suburbs.
The proximity of Friday’s earthquake to the MDF suggests that this fault line may have played a role in triggering the seismic activity.
According to geologists, the region’s tectonic setting is influenced by both local fault movements and broader seismic activity generated by the ongoing collision between the Indian and Eurasian plates in the Himalayas.
A Seismically Active Zone
Historically, the Delhi-NCR has experienced moderate seismic events, typically ranging between magnitudes 2.0 and 4.5. While these are not usually destructive, they serve as important reminders of the region’s vulnerability.
The intricate network of fault lines coupled with the seismic energy from the Himalayan belt makes this region highly sensitive to earthquakes.
Experts warn that although most quakes in the area are mild to moderate, the possibility of a stronger event in the future cannot be ruled out.
Urban development in this densely populated zone necessitates rigorous enforcement of earthquake-resistant construction norms and greater public awareness.
Public Reaction and Safety Measures
Friday’s tremor caused brief panic in some localities, with residents stepping out of buildings in precaution. However, no emergency evacuations were reported.
Authorities reiterated that there was no cause for alarm but advised the public to remain alert and follow safety guidelines in the event of future tremors.
Emergency services across the NCR remained on standby, and no disruptions were reported in transportation or communication networks.
The Delhi Disaster Management Authority has urged citizens to stay informed through official channels and avoid spreading unverified information.
As the region continues to experience mild seismic disturbances, experts stress the importance of preparedness.
Simple steps such as securing heavy furniture, identifying safe spots within homes, and participating in earthquake drills can greatly reduce risks during such events.
Conclusion
The consecutive earthquakes in Jhajjar highlight the persistent tectonic activity beneath the Delhi-NCR region. While the recent tremors were not severe, they underscore the need for continued vigilance and infrastructure resilience in one of India’s most densely populated and seismically sensitive areas.
