These volcanoes are a part of mountain, however, not of all them. For instance, Mount Fuji in Japan, Mount Vesuvius in Italy, and Mounts Rainier and St Helens In Washington.
II THE DANGERS ASSOCIATED WITH VOLCANIC ERUPTIONS .
II.1 The dangers to human health:.
Volcanic eruptions are one of the major disaster that can give human to die out, for instance they are released a cloud of poisonous carbon dioxide into the sky after erupted (as known as Strombolian). Lava rockets tons of ash, hot rock blew out into the earth's atmosphere (Phreatic), and devastating a wide area and killing more than 1,500 people in Cameroon, West Africa in 1986.Therefore it send the mushroom cloud like a nuclear explosion. After this volcanic eruption event, the atmosphere and weather in the earth are changed. It is a main reasons that human health have effected serious such as cancer, lung disaster genetic problems in further generations causes by inside a mushroom cloud have a giant poisonous carbon dioxide.
II.2 The dangers to the environment:.
