Threats in the United States Volcano eruptions cost the United States quite a lot of monetary values, as a result of damage to properties. In the United States there are up to sixty active volcanoes, some explosive and others non-explosive. Mitigating the effects of the volcano eruptions is important to reduce future deaths and damage. This essay considers possible ways of mitigating the future damage and deaths from volcano eruptions, as well as the volcano risk areas in the United States.

environment, a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes

cerebrates the volcano has erupted about of once every 6 years over the past 3000 years. The Hawaiian Volcano Observatory celebrated the 30th anniversary of Mauna Loa's last eruption (in 1984) on March 25, 2014. Mauna Loa is the worlds most sizably voluminous mountain and volcano, it is a basaltic shield volcano in its tardy mature stage of life about 600,000-1,000,000 years old. Albeit it does not erupt as much as the volcano adjacent to it (Kilauea) it is still one of the most active volcanos in the world

environment and people. In all recent eruptions at the volcanos I am going to discuss there has been no deaths to the local people.
