A sudden violence of volcanic eruptions causes catastrophe and devastation. Volcanic Eruptions have devastating impact of volcanic activity on nearby landscapes and communities. Many people are killed, and large numbers of people have to abandon their homes and lands forever. Even the whole world’s climate was changed for a while as a result of an eruption. Governments have to pay enormous amounts to rebuild cities and towns. People become more terrified and havoc fills surrounding towns.
Fortunately, volcanoes exhibit precursory unrest that if detected and analyzed in time allows eruptions to be anticipated and communities at risk to be forewarned with reliable information in sufficient time to implement response plans and mitigation measures.
