Vulnerability to Lightning

Study vulnerability to lightning for UPSC. Notes on India's lightning strike data, affected regions, deaths, and disaster mitigation steps.

It is commonly known that lightning strikes occur in both time and space all across the planet. However, there is a dearth of knowledge regarding how lightning affects people in the underdeveloped countries. The number of fatalities and injuries worldwide is reportedly between 6000 and 24,000 every year.

  • Lightning is the most significant cause of accidental deaths due to natural causesin India, accounting for an average of 2,000-2,500 deaths per year.
  • Scientists in India cannot study lightning because there is insufficient data, and lightning events have not been tracked efficiently. Only a single group of researchers works full-time on thunderstorms and lightning at the Indian Institute of Tropical Management (IITM) in Pune.
  • In India, there are quite a few thunderstorms each year. Each storm can produce dozens or even hundreds of lightning strikes. A researcher from IITM says,  “Lightning incidents have been showing an increasing trend over the last 20 years, especially near the Himalayan foothills”.

Due to extensive exposure during labor-intensive agriculture during the day when thunderstorms are most common and while residing in lightning-unsafe buildings at night, lightning sensitivity is still a significant problem in many developing countries.
