Old Heatwave Map Used as Sound Waves Recorded During Janata Curfew

The claim shared along with the image is false. Firstly, it’s not a map that shows sound waves, rather it’s a heatwave map of India. Secondly, the map is not from 22 March but dates back to June 2019.

Consequently, we searched on Google with keywords ‘heatwave map India’ and found a tweet shared by Copernicus EU on 4 June 2019. As per the tweet, the map shows the land surface temperature on 2 June and 4 June 2019.

It is noteworthy that the map, tweeted in 2019, which is actually a GIF, does not have any mention of ‘NASA Map of Sound waves’, like in the one that is viral on social media.

July 2019 was the hottest July in recorded history of India. As much as 65.12 percent of the population was exposed to a temperature of over 40 degree celsius between the months of May and June in 2019, an IndiaSpend report had then stated.
