Volcanoes & Lava

  1. 1. S tromboli , Italy - November 2007 . A bright yellow blob of viscous lava appears in the NE vent, forms a bubble and explodes. After the initial explosion, several powerful jets of spatter-rich erupt from the opened vent. (Song : Lava by Alkistis Protopsalti & Haris Alexiou) Click to continue
  2. 2. A volcano is a geological landform usually generated by the eruption through a vent in a planet's surface of magma, molten rock welling up from the planet's interior. Volcanoes of various types are found on other planets and their moons as well as on earth. Roughly defined, a volcano consists of a magma chamber, pipes and vents. The magma chamber is where magma from deep within the planet pools, while pipes are channels that lead to surface vents, openings in the volcano's surface through which lava is ejected during an eruption. North - western view of Mt. Fuji (Japan) over Lake Shoji which formed by damming the old lake with the Aokigahara lava flows erupted in 864 .
  3. 3. Though the common perception of a volcano as a mountain spewing lava and poisonous gases from a crater in its top is not wrong per se, the features of volcanoes are much more complicated and vary from volcano to volcano depending on a number of factors. Some volcanoes even have rugged peaks formed by lava domes rather than a summit crater, whereas yet others present landscape features such as massive plateaus. Vents that issue volcanic material (lava, which is what magma is called once it has broken the surface, and ash) and gases (mainly steam and magmatic gases) can be located anywhere on the landform. S antorini , Greece - View from Mikri Kameni across the caldera towards the Skaros shield. The houses of Imerovigli are seen on top of the caldera rim.

  14. 14. Chaitin volcano, Chilie May 6,2008 after 9 . 000 years of silence, Chile's Chaitin volcano is erupting with lava, ash and lightning Seen from space on May 3, the plume from the Chaitin volcano drifts across the Andes mountains, Chile's eastern border, and the width of Argentina. Ash covers the Yelcho River near Chaitén, Chile, on May 4, 2008, after an eruption of the Chaitén volcano. Photographed on May 4 from the evacuated town of Chaitin, Chile's Chaitin volcano has sent ash as high as 12 miles (19 kilometers) into the sky
