Dr. OP Mishra, Director of the National Centre for Seismology (NCS), reassured Delhi residents on Monday that there is no cause for concern following a 4.0-magnitude earthquake that struck the national capital early that morning. He explained that aftershocks of lesser magnitude are a natural occurrence and will subside over time.
The earthquake, which originated just 5 km below the earth’s surface, jolted Delhi and surrounding areas at 5:36 am. The epicenter was located in Dhaula Kuan, an area known to fall under a seismic zone.
In an interview with ANI, Dr. Mishra stated, “Delhi has experienced minor earthquakes in the past. Today’s earthquake occurred in Dhaula Kuan, an area where, in 2007, a 4.7-magnitude quake took place. There is nothing to worry about as it is a seismic zone.”
Explaining the cause of the earthquake, Mishra added, “The earthquake was caused by in-situ material heterogeneity. After a 4.0-magnitude event, aftershocks will generally be around 1.2 magnitudes less, which is a natural process and will help in the healing of the area.”
Following the tremors in Delhi, more tremors were felt in Bihar at around 8:02 am, originating from just 10 km beneath the Earth’s surface. Fortunately, no casualties or significant damage were reported from either event.
Dr. Mishra also clarified that the earthquakes in Delhi and Bihar were unrelated, as the cause of each depends on the rock shearing strength, which varies between the two regions.
He further emphasized that while people should always be cautious during seismic events, it is not the earthquakes themselves that cause harm, but rather the buildings and infrastructure. “Delhi has always been safe during shallow earthquakes. Modern buildings are designed to absorb and reduce seismic waves,” he added.
