Eruption of volcano Merapi in 2010. Pyroclastic flows destroyed several villages. More than 350 persons were killed.
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.
This gallery shows fotos from Vesuvius and Pompeii. The ancient roman city was destroyed by an eruption of Vesuvius on 24th August 79.
While the other volcanoes of Vanuatu are only sporadically active, the Yasur is permanently active for at least 800 years and has some similarities with the Stromboli in Italy. The activity of the small volcano is strombolian. Yasur erupts even at shorter intervals than Stromboli. On average, 500 explosions at Yasur can be registered per day. In the “wild” times the bursts tend towards volcanic type and can then be stronger by far than the regular eruptions of Stromboli. So it is the Yasur not rare that lava rocks fly up to the crater rim. In autumn 2008, two Asian tourists were killed during one of these eruptions. Their guide survived the disaster.
The 405-meter-high volcano is easily accessible. The cone was built in the caldera of an older volcano that collapsed after a major eruption. The special feature here is that the bottom of the caldera raises an average of 15 centimeters per year.
