Earthquake Jolts Delhi-NCR, 2nd Time in Two Days

Delhi-NCR Earthquake: A 3.7-magnitude earthquake struck Delhi-NCR on Friday evening at 7:49 pm, with tremors felt across the region. According to the National Centre for Seismology, the earthquake originated in Jhajjar, Haryana, at a depth of 10 km.

This comes just a day after a stronger 4.4-magnitude earthquake hit the same area. No reports of damage or injuries have been received so far. 

The Delhi-NCR region and its surrounding areas, such as Jhajjar and Rohtak, sit atop a crucial network of active geological fault lines. These fault lines include 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). As per experts, the region's tectonic activity is influenced by both distant Himalayan movements and local geological activity.

The seismologists suggested that aftershocks are common following a main earthquake and can continue for a few days. Typically, these are of lower intensity than the original tremor. They consider this a positive sign, as it indicates the gradual release of built-up tectonic energy, reducing the risk of a larger event.

The seismologists further said that earthquakes in this region, like the recent ones, are often moderate, ranging between magnitude 2.0 and 4.5, but indicate ongoing tectonic stress. The July 11 quake's proximity to the MDF suggests this fault line could have been responsible for the tremor.

In addition to this, given the number of active faults and the region's proximity to the Himalayan collision zone, Delhi-NCR remains sensitive to both moderate and stronger seismic events. The region's complex geology and tectonic activity make it prone to earthquakes, and residents should be prepared for future tremors. 

Further details regarding the earthquake are awaited.
