Which natural disaster caused widespread devastation in Kerala in 2018?

Cyclone Ockhi
Kerala Floods
Tsunami
Heatwave

The correct answer is: B) Kerala Floods.

The Kerala floods of 2018 were a series of floods that affected the Indian state of Kerala in August 2018. The floods were caused by heavy monsoon rains, which caused rivers to overflow their banks and inundate low-lying areas. The floods caused widespread damage to infrastructure and property, and left hundreds of thousands of people homeless. The floods also claimed the lives of over 400 people.

Cyclone Ockhi was a severe tropical cyclone that affected the Indian states of Kerala and Tamil Nadu in December 2017. The cyclone caused widespread damage to infrastructure and property, and left hundreds of thousands of people homeless. The cyclone also claimed the lives of over 200 people.

A tsunami is a series of large waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami.

A heatwave is a period of abnormally hot weather, lasting for days or weeks, that can cause illness and death among vulnerable populations. Heatwaves are becoming more common and severe due to climate change.
