The Delhi government’s draft disaster management plan warns that should a powerful earthquake strike the national capital, it would wreck more devastation than a nuclear bomb explosion. Six minor earthquakes in 10 days sometimes is the precursor to a large one. The current local seismic behaviour is very similar to the one in Gujarat a few years back. The net effect can be more devastating than even a nuclear bomb in Delhi, the draft, submitted to the Delhi Disaster Management Authority (DDMA) headed by Lt-Governor Najeeb Jung for approval, states. For disaster preparedness, the draft plan proposes to put the onus of strengthening mobile towers on mobile service providers, a senior government official said.
