At 11.30 AM on Wednesday, a siren announced the beginning of a massive emergency drill to evaluate the city's preparedness for an intensive earthquake.
On trial today are government agencies, emergency forces, and hospitals. The idea is to measure the response to an earthquake measuring 7.8 on the Richter scale.
Six metro stations were closed for more than 30 minutes and traffic in parts of Central, South and North Delhi was diverted to allow ambulances and fire engines to move through.
