Delhi Shaken by Second Earthquake of the Week: Understanding the Risks and Preparations
A 3.7 magnitude earthquake struck Haryana’s Jhajjar district on July 11, 2025, at 7:49 pm, with tremors felt across Delhi-NCR, marking the second earthquake of the week in the region. The National Centre for Seismology confirmed the earthquake’s details, including its epicentre, depth, and magnitude, while authorities reported no immediate damage or casualties. This event follows a 4.4 magnitude earthquake that occurred in the same district on Thursday, highlighting the seismic activity in the region.
The earthquake that jolted Delhi and its surrounding areas on July 11, 2025, was a significant event that has raised concerns about the region’s seismic risks. At 7:49 pm, a 3.7 magnitude earthquake occurred in Haryana’s Jhajjar district, with its epicentre located at 28.68°N latitude and 76.72°E longitude, at a depth of 10 kilometres. According to the National Centre for Seismology (NCS), this earthquake is the second to hit the region in the same week, following a 4.4 magnitude earthquake that struck the same district on Thursday. The tremors from both earthquakes were felt across Delhi-NCR, including areas such as Noida, Gurugram, and Faridabad. Fortunately, there were no immediate reports of damage or casualties.
Understanding Earthquakes in Delhi-NCR
Delhi falls under Seismic Zone IV, as classified by the Delhi Disaster Management Authority, which indicates a high damage risk zone vulnerable to moderate to strong earthquakes. The region’s seismic activity is a concern due to its location in a seismically active area, where several tectonic plates intersect. The Himalayan region, which is not far from Delhi, is a significant contributor to the seismic activity in the area. Earthquakes can occur without warning, making it crucial for residents and authorities to be prepared and have emergency plans in place.
Key Highlights of the Recent Earthquakes
Some key points about the recent earthquakes in the region include:
* The first earthquake occurred on Thursday, with a magnitude of 4.4 on the Richter scale.
* The second earthquake occurred on July 11, 2025, with a magnitude of 3.7.
* Both earthquakes had their epicentre in Haryana’s Jhajjar district.
* The depth of the second earthquake was 10 kilometres.
* Tremors were felt across Delhi-NCR, including areas such as Noida, Gurugram, and Faridabad.
* There were no immediate reports of damage or casualties from either earthquake.
The National Centre for Seismology confirmed the details of the second earthquake in a post on X, stating, “EQ of M: 3.7, On: 11/07/2025 19:49:43 IST, Lat: 28.68 N, Long: 76.72 E, Depth: 10 Km, Location: Jhajjar, Haryana.” This information is crucial for understanding the earthquake’s impact and for planning future preparedness and response efforts.
Preparing for Earthquakes in Delhi-NCR
Given the region’s seismic risks, it is essential for residents, authorities, and organizations to be prepared for earthquakes. This includes having emergency plans in place, conducting regular drills, and ensuring that buildings and infrastructure are earthquake-resistant. The Delhi Disaster Management Authority has classified Delhi under Seismic Zone IV, which means that the region is at a high risk of damage from moderate to strong earthquakes. By understanding this risk and taking necessary precautions, residents and authorities can minimize the impact of earthquakes and ensure a safer community.
Importance of Earthquake-Resistant Construction
Earthquake-resistant construction is critical in reducing the risk of damage and casualties during earthquakes. Buildings and infrastructure should be designed and constructed with seismic safety in mind, using materials and techniques that can withstand earthquake forces. This includes using reinforced materials, designing buildings with flexible frames, and ensuring that structures are anchored to the ground. By investing in earthquake-resistant construction, residents and organizations can protect their properties and lives.
In conclusion, the recent earthquakes in Delhi-NCR are a reminder of the region’s seismic risks and the need for preparedness and emergency planning. By understanding the risks and taking necessary precautions, residents and authorities can minimize the impact of earthquakes and ensure a safer community.
Conclusion:
The second earthquake of the week in Delhi-NCR has highlighted the region’s seismic activity and the need for preparedness. As the region falls under Seismic Zone IV, it is crucial for residents and authorities to take necessary precautions, including having emergency plans in place and ensuring earthquake-resistant construction. By working together, we can minimize the impact of earthquakes and create a safer community.
