This is Kerið, a volcanic crater lake in the Golden Circle.It is now believed that Kerið was a cone volcano which erupted and emptied its magma reserve. The cone then collapsed into the empty magma chamber due to its weight.

photos of sakurajima, the most active volcano in japan, by (click pic) takehito miyatake (previously featured) and martin rietze. volcanic storms can rival the intensity of massive supercell thunderstorms, but the source of the charge responsible for this phenomenon remains hotly debated.

in the kind of storm clouds that generate conventional lightning, ice particles and soft hail collide, building up positive and negative charges, respectively. they separate into layers, and the charge builds up until the electric field is high enough to trigger lightning.

but the specific mechanism by which particles of differing charges are separated in the ash cloud is still unknown. lightning has been observed between the eruption plume and the volcano right at the start of an eruption, suggesting that there are processes that occur inside the volcano to lead to charge separation.  

volcanic lightning could yield clues about the earth’s geological past, and could answer questions about the beginning of life on our planet. volcanic lightning could have been the essential spark that converted water, hydrogen, ammonia, and methane molecules present on a primeval earth into amino acids, the building blocks of life.

Koyashskoe lake in Kerch, (Crimea). Located in the Opukske Reserve, Lake Koyashske is considered to be the saltiest in Crimea – a liter of its water contains 350 grams of salt. The lake’s main highlight is its changing-colour properties that depend on the season(when it’s hot, the water is pink-coloured). The unusual color of the lake is due to the microscopic algae living in the water. Another reason for the lake’s red color is the high population of brine shrimps that live there.
