Kawah Ijen: blue burning sulfur

Incredible video footage of burning sulfur on Kawah Ijen in Java. Kawah Ijen volcano in Indonesia, is the own location you can certainly watch the electric blue fire of burning sulfur.

I traveled together with my indonesian friend and guide Andy. My friends Martin Rietze and Thorsten Böckel were also one of the party. We climbed the step crater walls short before sunset: just during night time the blue flames of the burning sulfur are visible.

About Kawah Ijen

The Ijen volcano complex is a group of stratovolcanoes in East Java, Indonesia. The volcanoes are inside a larger caldera, which is about 20 kilometers wide. Ijen volcano has a one-kilometer-wide acidic crater lake. The lake is the site of sulfur mining operation. Miners carried Sulfur-laden baskets by hand from the crater floor.

Sinabung: pyroclastic flows

The eruption of Mount Sinabung started in September 2013, with series of small explosive eruptions. A  lava dome begun to grow in December and some weeks later first pyroclastic flows occurred. The Geonauts reached the volcano in mid-January 2014. We documented the eruption for one week. On some days the volcano was covered by clouds, or the activity was less. But during two nights we observed plenty pyroclastic flows. In some of them we observed volcanic lightning in the rising ash clouds. Most appeared in the night of the 14th January.

The village Sigarang Garang was very badly damaged by the eruption. Many roofs had collapsed under the weight of volcanic ash.

Batu Tara: island of taboos

Batu Tara is a small strato volcano close to the coast of Flores in Indonesia. Batu Tara is located on Komba Island. It’s an inhabitant Island, the spirits of the death living on. That is the reason why komba is taboo for some Indonesians.

Batu Tara is similar to Stromboli in Italy. Its frequent eruptions are from same type. The eruptions occur every 10 to 20 minutes. Scoria rolls over the flank of the volcano into the sea.

Kawah Ijen: burning sulfur and blue flames

Kawah Ijen is a well known Volcano in east Java. In its summit crater lies an acid lake and on the shoreline of this lake degases many fumaroles. The fumaroles transport tones of sulfur from earth interior to its surface. The sulfur condenses close to the fumaroles and thick layers of the yellow mineral solidify in one part of the deep crater.  Every day hundreds of miners climbing down the crater and dig the sulfur. In two baskets they carry the minerals to a weight station, 3 km downhill.

Anak Krakatau: “child of Krakatau”

Anak Krakatau is the “child of Krakatau”. The new island growth up since 1926 and established a small stratovolcano in the caldera formed after the disaster from 1883. In this year the former island Krakatau destroyed itself in a very huge eruption. Tsunamis, caused by the collapse of the volcano, killed more than 36.500 people.

The eruptions of Anak Krakatau are not so disastrous like the one in 1883, but still power full enough, to threaten observers close to the volcano. In 2010 Chris and I visited Anak Krakatau and we spend 2 nights on the island. Vulcanian explosions threw lava bombs above our heads, smashed into the sea. An adventure we will never forget.

Bromo: Gods and eruptions

Mount Bromo is a volcano in central Java. The last eruption was in 2011, when the volcano was active for many months. The landscape was covered by volcanic ashes. The plants on the fields withered and the airport of Surabaya was closed on several days. But 3 months after the eruption the Kasada celebration was hold. Many Hindus climbed the crater rim and sacrificed animals, vegetables and fruits to their god Brahma.
