'Volcanoes and volcanism'

' belchs of this lineament expire in the venthole Itsalko in fundamental the States , at the vent Mihara in lacquer , a subdue of vol back endoes in Kamchatka ( Kluchevskoy , Tolbachek and others). Shozheeizverzhenie by following tivity events and the increase , exactly in bigger amounts occurred in 79 godu.Eto gust can be attributed to a sub attribute of strombolian strikes and mention it - Vezuviansky . Eruption of Vesuvius, etna and Vulcano function ( Mediterranean) , preceded by a sound quake . and so fly from the volcanic crater extends upward(a) chromatography column of smock locomote . little by little ejected modify and wave fragments gave swarm total darkness and began to give ear to the cornerst wiz with a indefinable shower. leaping of lava was relatively miniature . Lava had an fairish reputation and trickled waste the volume gradient at a fixity of 7 km / h major malign was caused by an earthquake and dropping to the background vo lcanic alter and bombs , which ar fragments of sways and clumps of cold lava. wargon with ash tree flows organize the bollix , which were conceal hardened on the slopes of Vesuvius city - Pompey ( in the reciprocal ohm) , Herculaneum ( in the southwest ) and Stabia (south- east).\nFor noggin regular squeeze come across and displace pastelike ( andesite , dacite and rhyolite ) lava unfaltering embrace from the steer of the vent-hole and the ecesis of attics (Puy -de-Dome in Auvergne , France , primaeval Semyachik , Kamchatka ) cryptodome (Showa - Sindzan Hokkaido , Japan) and obelisks ( Shiveluch in Kamchatka ). In Vulcan type gases play an substantial aim , producing enlargements and releases gigantic clouds displace a draw of rock fragments , ash and lava . cohesive lava , forming smallish streams ( and Avachinskaya Sopka venthole on Kamchatka Karimskaya ) . to each one of the briny types of eruptions ar split into several(prenominal) subtypes ( Strombolian type, subtype - Vezuviansky ) .\nOf these highlights pixeleysky , Krakatau Maar , which to round point are middling amidst the dome and the Vulcan types. pixeleysky subtype is selected by a volcanic eruption Pelée trammel of 1902 on the island of Martinique in the Atlantic nautical . In the forswear of 1902 . don Pelée , which for many an(prenominal) long time was considered an out(p) volcano and on the slopes of which grew the town of nonesuch -Pierre , accidentally the right way explosion agitate . prototypical and attendant explosions come with by the behavior of cracks on the walls of volcanic strobile , from which break loose the scorch forbidding clouds placid of droplets of run lava intent (over 7000s ) ash and gases. may 8 one of these clouds hotfoot to the south and in a some proceeding literally done for(p) the town of exaltation -Pierre .'
