Earlier on Thursday morning, a 4.4-magnitude earthquake jolted the citizens of the region in the morning at around 9:04 which too originated in Jhajjar. Although it lasted for only a few seconds, it caused panic among the residents.

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

The Delhi-NCR region and its surrounding areas, such as Jhajjar and Rohtak, sit atop a complex network of active geological fault lines.

These 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).

Tectonically, the region is influenced by both distant Himalayan movements and local geological activity. One of the most significant fault lines in the region is the Mahendragarh-Dehradun Fault, which links the stable Indian craton to the active Himalayan Frontal Thrust.

The MDF stretches from Mahendragarh in Haryana to Dehradun in Uttarakhand, cutting across densely populated zones, including the NCR.
