Amazing Alien Landscape On Earth: Blue Lava Flows From Kawah Ijen - Indonesia’s Deadly Acid Volcano
MessageToEagle.com -There are places on this planet that are just as beautiful as hostile.
There are also a few people who dare to risk their lives in order to photograph and film some of the most hazardous environments on Earth.
One of them is Photographer Olivier Grunewald who has been taking photos of volcanoes since 1997.
In 2008, Grunewald learned about the Kawah Ijen, Indonesia’s deadly acid volcano and he decided to photograph and create a documentary about one of the most beautiful and dangerous volcanoes on this planet.
Supervolcanoes are unpredictable ticking time bombs with the power to destroy the entire world. This is one of the reasons why they should be studied and monitored carefully. They are also often very beautiful, like for example the Dallol Volcano which located in the Danakil Depression in Ethiopia.
Kawah Ijen is part of the Ijen volcano complex in East Java, Indonesia.
The volcano is 2,600 meters tall (8,660ft), topped with a large caldera and a 200-meter-deep lake of sulfuric acid.
While the sulfur appears bright red during the day, at night it gives off an eerie blue light with flames that can reach up to five foot in height. It is truly amazing!

Ambrym is a large basaltic volcano with a 12-km-wide caldera. It is not only one of the most active volcanoes of Vanuatu, but also in the world. Ambrym’s caldera is a wide, impressive moon-like landscape containing an ash plain, cut by innumerable erosion gullies and containing several active craters and recent lava flows.
The caldera is believed to have formed during a major plinian eruption with dacitic pyroclastic flows about 1900 years ago. Activity after the caldera formation was concentrated around two vents that have become large complex craters called Marum and Benbow. Often, both Marum and Benbow (as well as other craters) contain small lava lakes, which occasionally erupt lava flows onto the caldera floor, or even exit the caldera through erosion gaps.
To capture close-up footage of this lava lake on the Pacific island of Vanuatu, Geoff Mackley and his colleagues had to brave excruciating heat and some rather precarious-looking abseiling.

Fox’s Landing, Hawaii Overtaken By A Lava River
When a lava flow starts to cool, the outer layer of the lava freezes into solid rock, and once the pressure of the liquid inside builds up, the skin cracks open with a loud pop and lava oozes out again. Here, lava oozes from a fresh crack on a cooling lava flow at Mount Kilauea on the big island of Hawai’i.
