Why is Delhi particularly vulnerable to earthquakes?

Delhi is particularly vulnerable to earthquakes because it is located in seismic zone 4, the second highest risk category in India. This vulnerability stems from its proximity to Himalayan earthquakes and the movement of the Indian plate and local fault systems. The city's foundation of soft alluvial soil amplifies seismic waves, making tremors feel stronger than their actual magnitude. Additionally, many of Delhi's buildings are older constructions with inadequate spacing and may not be equipped to handle significant tremors. Scientists have warned that a powerful earthquake of over 8.0 magnitude in the Himalayas is overdue, which could have devastating consequences for Delhi and northern India.
