Overnight colour change in lonar lake of Maharashtra

Lonar lake also known as lonar crater is a notified National Geo-heritage monument located at Lonar in buldhana district Maharashtra India . It was created by an asteroid collision with Earth impact during the pleistocene Epoch. It is the third largest crater that was formed because of meteorite strike.

Lonar lake is located around 500 km from Mumbai, the lonar lake in buldhana district is a popular tourist destination. The colour of water in the lonar lake formed after a meteorite hit the Earth 50,000 years ago has changed to pink with experts attributing it to the salinity and presence of algae in the lonar lake water body. It's average depth is 137 m.

The change in the colour of the water of the lake has not only surprised the villagers but also surprised the scientist. The lake has saline water body with pH of 10.5

There is no oxygen below one meter of the lake's surface. The level of water in the lonar lake is currently low as compared to past few years or past few days because there is no rain to give it fresh and clean water.

The low level of water may lead to an increase salinity and change in the behavior of algae because of the atmospheric changes during the lockdown this can be a reason in change.
