Why Delhi NCR gets frequent tremors: ‘Faults’ and earthquake zones, explained
Being a 'high-risk area' means earthquakes in Delhi and surroundings can go up to magnitude 5-6; on Thursday, the magnitude was 4.4
Tremors originating from Jhajjar (Haryana) in Delhi NCR shook the region on Thursday morning. The region experiences frequent tremors as it falls in Seismic Zone IV, the most vulnerable as per the division in India, meaning it has “fairly high seismicity”.
Being a “high-risk area” thus means earthquakes in Delhi and surroundings can go up to magnitude 5-6. On Thursday, the magnitude was 4.4.
An earthquake of magnitude 7-8 is an “occasional” occurrence in Delhi.
Data available from the year 1720 says only five quakes of magnitude 5.5 to 6.7 have been recorded in Delhi or surrounding areas in this period.
The Delhi-Haridwar Ridge and Delhi-Moradabad Fault are two major lineaments that pass through Delhi and make it more sensitive to earthquakes.
Delhi's earthquake dangers: Hills nearby, faults underground
Several other weak zones and faults near Delhi include the Mahendragarh-Dehradun Subsurface Fault, the Sohna Fault, Great Boundary Fault, Delhi-Sargodha Ridge, Yamuna river lineament and Ganga river lineament, among others, according to the National Center for Seismology (NCS).
Delhi's proximity to the Himalayas, which are seismically very active, also makes it prone to tremors.
