Delhi is at risk of earthquake due to its location in seismic zone and its proximity to active fault lines and Himalayas. Experts from the National Centre for Seismology (NCS) have classified Delhi as seismic zone IV, indicating significant earthquake risk. However, it’s crucial to understand that earthquakes cannot be predicted so there’s no advance warning to prepare.
Delhi’s Earthquake Risk: Why It’s Vulnerable
Several fault lines surround Delhi including the Delhi-Haridwar ridge, Mahendragarh-Dehradun subsurface fault, Moradabad fault, Sohna fault, great boundary fault, Delhi-Sargodha ridge, Yamuna River lineament, and Ganga River lineament. Additionally Delhi is near the Himalayas seismically active zone due to collision of tectonic plates.
Understanding Delhi’s Fault Lines: What You Need to Know
Recently, Delhi-NCR experienced multiple earthquakes within a short period, emphasizing the region’s vulnerability. On a specific day 6.2 magnitude earthquake hit Nepal, causing tremors in northern India, including Delhi. The NCS highlighted the presence of fault lines like Himalayan Frontal Thrust (HFT), Main Boundary Thrust (MBT) and Main Central Thrust (MCT) contributing to seismic activity in the region.
Delhi-NCR’s Earthquake Experience
Researchers have discovered variations in the Himalayan terrain, indicating the potential for significant earthquakes. Historical data shows that Delhi-NCR has experienced earthquakes with magnitudes ranging from 5.5 to 6.7 since 1720. Notably, faults like Delhi-Haridwar ridge and Delhi-Moradabad faults are capable of generating substantial earthquakes.
Staying Safe: Delhi Disaster Management’s Advice
Given the risks, Delhi Disaster Management Authority advises developing a prevention and preparedness plan considering the potential effects of a significant earthquake. It’s crucial for residents and local authorities to be aware of the seismic threats and take necessary precautions, even though earthquakes cannot be predicted in advance.
