New Delhi, July 11 -- Delhi and the National Capital Region (NCR) was jolted by strong tremors on Thursday morning after an earthquake of magnitude of 4.4 on the Richter scale struck the region, with its epicentre in Haryana's Jhajjar . People were seen rushing out of buildings and homes, however, no loss to life or damage to property was reported. According to the National Centre for Seismology (NCS), the earthquake had a depth of 10 kilometres and was recorded at 9.04am. The Bureau of Indian Standards classifies the entire country into four seismic groups - ranging from zone II (low intensity) to zone V (very severe). Delhi-NCR falls into zone IV (severe), making seismic activity a fairly common occurrence, and Thursday's earthquake was no anomaly. On February 17, similar tremors were felt in the region after a 4.0 magnitude earthquake with its epicentre in south Delhi's Dhaula Kuan was recorded. Data from NCS shows that the region has recorded 446 earthquakes between 1993 to 2025 within a 50 sq km radius of the Dhaula Kuan epicentre, ranging from a magnitude of 1.1 to 4.6, highlighting the high seismic activity of the region. While Delhi has three active fault lines running through it - the Sohna, Mathura and Delhi-Moradabad fault lines, the neighbouring Haryana region has seven such lines running across it. Delhi's proximity to the Himalayan region, which also is in a high seismic zone, further makes the capital prone to receiving aftershocks, according to experts....
