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 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.
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.

Stromboli is a very popular volcano in the Mediterranean Sea and known by the ancient Roman as “Lighthouse of the Mediterranean”, because of its long-lasting strombolian eruptions.
This picture gallery shows the evolution of the volcano since its last flank eruption in 2007 until 2013.
Nyiragongo is a high shield volcano in Demokratic Republic Congo. The volcano is located close to the border with Rwanda. The largest city nearby is Goma. The summit crater contains an active lava lake. In 2002 this lava lake drained through a fissure on the flank of the volcano. The lava flowed straight through Goma and ended in Lake Kiwu.
The eruption of Eyjafjoell-volcano on Iceland started 21st March 2010. The first part took place on a new fissure which opened on a saddle between the glaciers Myrdalsjoekull and Eyjafjallajoekull. The second part began some days after the first eruption ended. This was a powerful sub glacial eruption in the caldera at the summit of Eyjafjallajoekull.
Erta Alé is a shield volcano in Ethiopian Danakil-depression. Its summit rise just 612 m above the depression. In the Caldera are 2 pitcraters. In one of them a persistent lava lake is boiling. These pictures were made during my second expedition in this area in January 2008.
In Yellowstone National Park you can find the majority of the world’s geysers: Old Faithful, Castle, Grand and Steamboat are the most popular Geysers of Yellowstone. Other attractions are the hot springs and pools. Minerals and thermophilic algae and bacteria give the pools a colorful look. The origin of the hot water phenomena is a giant volcano. The Yellowstone volcano is a caldera volcano, which is known for its massive eruptions.
The National Park was founded in 1872 and was America’s first national park. The park prevents some of the largest populations of grizzly bears, wolves and herds of elk and bison.
I visited the Yellowstone two times: in 1991 and 2007. Here are the pictures of my last journey.
