Volcanic eruptions can be reduced and prevented by evacuation of people during volcano eruption warnings can save lives before the volcano erupts. Property can also be situated further away from the volcano to prevent as much economic losses and so on.
Volcanoes affect human life very badly. Volcanoes cause damage to property, land, by explosive blasts, different gas release, lava flow and mudflows. All of there factors affect human life up to large extent. The volcanic eruption that normally causes more damage is from fast moving volcanoes, hot flows if volcanic eruption is not predicted it could kill thousand of people and it affects the economy of the state as well.
In addition, they eject ash, which result clouds that are dangerous from air craft's. That subject of volcano logy is now at that stage or it has progressed up to that point that we identify the world dangerous volcanoes, we can estimate the danger or potential hazard. if we start instrumental monitoring it can detect the signals such as earthquake, if eruption is going to start to the gas emission so it will help in government to warn the people of surrounding areas, who are at the high risks so that can be shifted to some safe place. However it's not easy to prevent ourselves from volcanic eruptions effects but there dangerous effect can be reduced by using combination of science and by making different public policies.
