Minor tremors were felt in parts of Delhi and neighbouring Gurugram on Monday night. Reports of the earthquake poured in around 10.40 pm with several residents of Delhi-NCR taking to social media to report minor tremors.
The National Center for Seismology (NCS) reviewed the reports and confirmed that an earthquake of magnitude 3.7 on the Richter Scale struck Jhajjar in Haryana at 10.36 pm on Monday. The epicenter, 5 km deep, has been traced to a spot 10 km north of Jhajjar.
A similar earthquake of magnitude 2.8 was reported from Thoubal in Manipur at 8.20 pm on Monday.
The entire country has been classified into different seismic zones depending on the intensity of damage or frequency of earthquake occurrences.
According to the Delhi Disaster Management Authority (DDMA), “Delhi is located in zone IV which has fairly high seismicity where the general occurrence of earthquakes is of 5-6 magnitude, a few of magnitude 6-7 and occasionally of 7-8 magnitude.”
Two major lineaments, namely the Delhi-Haridwar ridge and Delhi-Moradabad faults, pass through Delhi-NCR. Both of these faults have the potential to generate earthquakes.
Others parts of the world also reported earthquakes on Monday, including Myanmar (magnitude 3.5), Bhutan (magnitude 2.9). An earthquake of magnitude 4.6 was also felt in China on Monday.
