The last one for today came from Indonesia ( thank you Mina ). It is showing Lake Toba . In Indonesian ot is called Danau Toba and is a lake and a supervolcano ( Now don't ask me what is the difference between a supervolcano and a normal one I really don't have the faintest idea ) . It is located in the Northern part of Sumatra island. It is the largest lake in Indonesia and the largest volcanic lake in the world . It is the site of a supervolcanic eruption that occured sometime between 69.000 & 77.000 years ago . It is the largest known explosive eruption anywhere on Earth in the last 25 million years! (ahm !!!) According to the Toba catastrophe theory , it had global consequences , killing most humans then alive and creating a population bottleneck in Central Eastern Africa and India that affected the genetic inheritance of all humans today . This hypothesis is not very widely accepted due to lack of evidence of any other animal decline or extinction even in enviromentally sensitive species , however it has been accepted that the eruption led to a volcanic winter with a worldwide decline of temperatures between 3 to 5°C ! ... By looking at the deep blue of the picture I would never have thought all this to be honest :)
