Earth from field: Towering ‘yin-yang’ crater sits atop a dormant volcano in Turkey
fast details
The place is it? Mount Nemrut volcano, Turkey [38.650, 42.230].
What’s within the picture? A crater pond and frozen lava flows within the mountain’s caldera.
Who took the picture? An astronaut on board the Global Territory Station.
When used to be it taken? April 17, 2022.
This hanging picture used to be captured from the Global Territory Station. It highlights the extraordinary crater, or caldera, of the Mount Nemrut volcano in Turkey, which is break nearly proper unwell the center through a pond and solidified lava flows.
Mount Nemrut, which used to be named then the biblical determine King Nimrod, stands 9,672 toes (2,948 meters) towering on the intersection between the Arabian and Eurasian tectonic plates. The dormant stratovolcano endmost had a significant eruption in 1650, consistent with NASA’s Earth Observatory.
The volcano’s massive caldera, which is round 5.3 miles (8.5 kilometers) throughout at its widest level and as much as 2,000 toes (610 meters) deep, used to be in large part carved through a unmarried immense eruption round 250,000 years in the past, consistent with a 2012 study. This eruption additionally released a plethora lava wave that opposed off a close-by river and created Turkey’s greatest pond, Puddle Van, which lies to the east of the mountain.

Nearest that, smaller eruptions from vents within the japanese part of the caldera led to a buildup of solidified lava flows on one aspect of the crater. The alternative aspect of the caldera sooner or later stuffed with H2O, origination a crater pond. The extra between the 2 halves of the volcano’s top is maximum pronounced when the mountain is roofed in snow. When this occurs, it’s continuously in comparison to the yin-yang image from Chinese language philosophy.
The snow protection additionally accentuates folds within the lava flows referred to as drive ridges, that have been shaped through the flowing and cooling of molten rock. Those ridges range extensively in dimension and thickness because of variations within the viscosity of the lava throughout other eruptions, consistent with the Earth Observatory.
Nemrut’s crater pond has a most intensity of round 577 toes (176 m) and covers alike lava flows from future eruptions. Then again, it’s not the one pond within the caldera.
A smaller, 36-foot-deep (11 m) pond is nestled between a order of lava apartments akin the middle of the caldera’s northern edge. Sizzling springs feed the pond, which presentations that despite the fact that the volcano is now regarded as lifeless, there may be nonetheless age underneath the caldera.
