Firefighters and emergency workers in India have been put on notice that there are far more cities vulnerable to earthquake than have been previous identified. In all, 81 new towns and cities were added to a list of areas prone to earthquakes, bringing the total to 107, according to government data released on March 16, 2016.
A big Himalayan earthquake is more than 500 years overdue-is expected, although no one can predict when this might be, recent earthquakes and tremors in the north continually remind people of their vulnerability. As many as 392 earthquakes of magnitude greater than three were located in and around India in 2015, the seismological network operated by Earth System Science Organisation-National Centre for Seismology reported, according to a statement given to the Lok Sabha (lower house of Parliament) by the Minister of Earth Sciences, on December 2, 2015.
No Indian metropolis has witnessed a serious earthquake, although Delhi lies in high-risk seismic zone 4. Mumbai, Chennai and Kolkata lie in zone 3 (with zone 5 being the highest). The only serious earthquake that modern India remembers is the earthquake that killed about 20,000 in Gujarat in 2001.
This is a significant challenge to firefighters and emergency workers.
