Eyjafjallajokullis a volcano in Iceland. Until 2010, it had peacefully slumbered for approximately 200 years. When it woke-up it did so in spectacular fashion, with an explosion that included volcano generated lightning and enough ash to affect air traffic.
Thereare 32 different volcanic systems in Iceland and they all form on the surface above where the crack is between the two plates. Rather than one huge crack with lava coming out everywhere, the lava finds the best ways to get to the surface and slowly builds up into volcanoes. But new volcanoes are being built all the time so in fifty years So, we needed another explanation why there have been so many volcanoes on Australia's east coast." Many of the volcanoes that form in Australia are one-off events, he said. "Rather than huge explosions like Krakatoa or Vesuvius, or iconic volcanoes like Mount Fuji, the effect is more like the bubbles emerging as you heat your pancakeTheflanks of the volcano have extremely low slopes characterized by extensive lava flows and channels. The average flank slope on Alba Mons is only about 0.5°, over five times lower than the slopes on the other Tharsis volcanoes. The volcano has a central edifice 350 km wide and 1.5 km high with a double caldera complex at the summit.
TheIndonesian island of Java is almost entirely of volcanic origin, and contains numerous volcanoes, 45 of which are considered active volcanoes. As is the case for many other Indonesian islands, volcanoes have played a vital role in the geological and human history of Java. Indonesiahas 147 volcanoes, 129 of which are active. They spread along the islands of Sumatra, Celebes, Java, Bali, Nusa Tenggara, Maluku, Lesser Sunda, and Sulawesi islands. Why does Indonesia have so many volcanoes? Tectonically, the active volcanoes are the result of a collision between 3 primary tectonic plates: The Eurasian Plate moving south x3Fb.
