On Friday an earthquake of medium intensity with 4.7 magnitude hit areas near Delhi. Over the last two months, Delhi faced a series of earthquakes, the Friday one as the latest. People ran out of their homes after they felt earthquake tremors. The earthquake hit at 07:50 PM IST.
The earthquake hit sixty kilometre south-west of Gurgaon in Haryana making it an epicentre, as per India’s National Center for Seismology.
The earthquake’s depth was thirty-five kilometre from the surface. For several seconds Delhi along with nearby areas felt strong tremors.
Delhi Chief Minister Arvind Kejriwal tweeted, “Mild earthquake tremors were felt in Delhi some time ago. Hope you are all safe, take care of yourself.”
However, no reports of damage property have been received yet.
Social media was abuzz with people reporting the quake, instantly sending #Earthquake to the top of the trends.
Delhi, which lies close to a faultline, is susceptible big earthquakes, geologists say. Since April 12, the Delhi National Capital Region (NCR) has recorded nearly 20 quakes.
The city falls in seismic zone IV – a very high-risk zone. India divided into four seismic zones — II, III, IV and V — according to increasing intensity and frequency of earthquakes.
An Earthquake With Magnitude 6 Can Destroy Delhi
If a magnitude 6 earthquake strikes Delhi, a large number of structures which do not follow safety norms are likely to be demolished, experts have said.
Professor Chandon Ghose of IIT Jammu earlier said that intense tremors can have a serious impact on Delhi. Chandon is an expert on earthquake engineering. At Richter scale 6.0, the effect of the earthquake in Delhi would be devastating, he said.
However, Seismologists say that it is common for Delhi and its neighbouring states to have these earthquakes. They say that due to the lockdown, people are at home thus they can feel low magnitude earthquakes. With COVID-19 pandemic and the imposed lockdown, there is less noise due to less traffic.
Last month, the South Delhi Municipal Corporation (SDMC) said it had started identifying such structures and asking for structural audit reports to ensure seismic stability of high-rise buildings.
