4.6-magnitude earthquake strikes Delhi-NCR, 14th tremor since April
New Delhi | Jagran News Desk: A low-intensity earthquake of magnitude 2.1 hit Delhi-NCR on Monday afternoon, said the National Centre for Seismology.
In a statement, the National Centre for Seismology said that the epicenter of the earthquake was at the Delhi-Gurgaon border and it occurred at 1 pm at a depth of 18 kilometre.
This was the 14th earthquake that the Delhi-NCR has reported since April.
Before this, a mild earthquake of magnitude 4.6 hit the national capital on May 29. The epicentre was in Rohtak in Haryana. Before that, an earthquake of 2.2 magnitude had hit the region on May 22 and its epicentre was in north Delhi's Pitampura.
The same location and the nearby areas were the epicentre of the earthquakes on April 12 and April 13 of magnitude 3.5 and 2.7, respectively. The quake occurred at a depth of five kilometres.
Of the five seismic zones, Delhi falls under the fourth zone. According to the Delhi Disaster Management Authority, seismicity around Delhi appears to be associated with a major geological structure, which is known as the Delhi-Hardwar Ridge.
It coincides with the extension of the Aravalli Mountain belt beneath the alluvial plains of the Ganga basin to the northeast of Delhi towards the Himalayan mountain.
Vineet Kumar Gahalaut, the Chief Scientist with the National Geophysical Research Institute, Hyderabad, had earlier said that the region around Delhi is known for seismic activities while adding that cities closer to Delhi like Alwar, Hisar, Sonepat, Ajmer have recorded seismic activities in the past.
"Areas adjoining Delhi witness smaller quakes every 10 days as it is on the Delhi-Aravalli fault line. Since they are in neighbouring areas and of small magnitudes, they don't garner much attention," Gahalaut, a former Director of the NCS, had said earlier.
