Two earthquakes hit Rohtak in Haryana in the span of an hour on Friday, tremors of which were felt in the national capital, said the National Centre for Seismology. Rohtak is nearly 60 km from Delhi.
The first quake, a medium intensity one of 4.6 magnitude, hit the Haryana city at 9.08pm at a depth of 5 km.
The second quake was of a lower intensity of magnitude 2.9 and occurred at the same location at 10pm, said the NCS.
There were no immediate reports of any loss of life or property.
The areas around Delhi are known for reporting low-intensity earthquakes and the capital has been jolted by a series of tremors over the last month. A low-intensity earthquake of magnitude 2.2 hit the national capital on May 15, which was the fourth since April 12, according to NCS.
On May 10, a medium-intensity earthquake of magnitude 3.4 hit the area near Wazirpur in northeast Delhi.
Wazirpur and its nearby areas were the epicentre of the earthquakes on April 12 and April 13, of magnitude 3.5 and 2.7, respectively. There are five seismic zones. Delhi falls in the fourth zone.
According to the Delhi Disaster Management Authority, seismicity around Delhi appears to be associated with a major geological structure known as the Delhi-Hardwar Ridge.
An earthquake of magnitude 2.8 had hit the national capital in 2004. Another 3.4 magnitude quake was recorded in the city in 2001, according to official data.
The major quakes recorded near the national capital were at Bulandshahr (magnitude 6.7) on October 10, 1956 and at Moradabad (magnitude 5.8) on August 15, 1966. Both are in western Uttar Pradesh.
