Earthquakes

Explain earthquake zones and mitigation in India.

Tectonic earthquakes are the most destructive.

The Indian plate pushes against the Eurasian plate; locked plates release energy along the Himalayan arc.

Peninsular quakes too: Gujarat (1819, 1956, 2001), Maharashtra (1967, 1993), along the Bhima fault.

The book's five zones: very high to very low damage risk; the Deccan is safest.

Mitigation: monitoring centres, GPS, vulnerability maps, earthquake-resistant design, light materials.

We cannot stop quakes; we can build to survive them.
