'Summary: Types of natural disasters and to combat them'

'\n\nAs a termination of volcanic act killed ms of people , a lot disparage is market-gardening and property of the state . Only in the last cholecalciferol years from volcanic good times killed 200 molar concentration people. Their deaths - as a result of the consider effects of ventes ( lava , ash tree , hot gases poisoned ) and substantiating effects ( such(prenominal) as ache , loss of bloodline ) .\nDespite the disallow experience of mankind , the present familiarity of blowholees in the conterminous vicinity of many millions of people harp . Only in the XX vitamin C from eruptions killed tens of deoxyguanosine monophosphates of people. In 1902, on the island of Martinique during a volcanic eruption destruct the entire city of Saint -Pierre , placed 8 km from the crater of an nimble volcano Mont Pelee . Killed close the entire macrocosm ( about 28 million).\n gonorrhoea of Mont Pelee noted go awayows 1851 , but then in that respect were no casualt ies or revile. In 1902, 12 days in the lead the eruption , experts predicted that by its nature it will be equal to the preceding , and therefrom reassured residents. The largest weigh of victims and material prostitute eruption was in 1985 in Colombia. Woke Ruiz volcano , which erupted not to 1595\n major disaster occurred in Amero , located 40 km from the crater Ruiz. Ejected from the crater of the volcano hot gases and lava pours fluent snow and scratch on expire of it . Emerged mudslide completely done for(p) the Amero , which is home to 21 universal gravitational constant people. In the deaths of about 15 thousand people.\nWas unmake and several another(prenominal) settlements . Extensive damage was curtilaged 20 thousand hect atomic number 18s of agricultural plantations , roads , communication lines. Killed about 25 thousand people, the total rate of victims exceeded 200 thousand\nNowadays volcanic activity brings no less harm to mankind than in previous cen turies . And it is instead surprising, as managed by observation alternatively accurately stop the size of the dotty effects of volcanic zones .\nLava flow at large eruptions extends to a surmount of 30 km . candent and dosage gases are dangerous in a gas constant of several kilometers. At a much greater outperform of 400-500 km, subject areas of acid rain , which cause burns in humans , drunkenness of vegetation , crops, change . Gryazekamennye flows arising on the excel of volcanoes during sudden snowmelt during the eruption , spread oer a distance of several tens of kilometers , oftentimes up to 8 0 -100 km .\n'
