What in news:

·         Scientists at IIT Kharagpur are developing detailed city-level maps that can help identify areas likely to experience maximum damage in the event of an earthquake.

About news:

·         Scientists at IIT Kharagpur are developing detailed city-level maps that can help identify areas likely to experience maximum damage in the event of an earthquake.

·         The research will help state governments quickly identify areas with high hazard risk and send in rescue and relief teams when a disaster strikes, without losing precious time manually surveying the affected region.

·         The system can also help state governments estimate the funds required for rescue and rehabilitation after disaster strikes.

·         IIT Kharagpur is among the list of institutes included in the Ministry of Earth Sciences’ Expression of Interest for seismic microzonation of eight ‘priority cities’ like Patna, Meerut, Amritsar, and Agra.

About Seismic microzoning:

·         It is a technique that involves mapping the different factors such as plate tectonics, soil quality, ground motion equations, topography, type of buildings etc. to understand which areas within a city may get most affected by an earthquake.

IIT Kharagpur:

·         The Indian Institute of Technology Kharagpur is a public engineering institution established by the government of India in 1951.

·         It was the first of the IITs to be established, and is recognized as an Institute of National Importance by the Government of India.

·         Internationally, IIT Kharagpur was ranked 308 in the QS World University Rankings of 2018.

·         The same rankings ranked it 62 in Asia and 24 among BRICS nations.

·         It was ranked 501-600 in the world by the Times Higher Education World University Rankings of 2018, 60 in Asia and 71 among BRICS & Emerging Economies University Rankings in 2017.

·         IIT Kharagpur ranked 2nd among engineering colleges in India by India Today in 2017.

 Earthquakes as Disaster:

·         Disaster is a sudden, calamitous event, bringing great damage, loss, destruction and devastation to life and property.

·          The damage caused by disasters is immeasurable and influences the mental, socioeconomic, political, and cultural state of the affected area.

·         India has been vulnerable to natural disasters on account of its unique geo-climatic conditions. Floods, droughts, cyclones, earthquakes, and landslides have been recurrent phenomena.

·         The Indian subcontinent has a history of devastating earthquakes.

·         The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a rate of approximately 47 mm/year.
