Predicting volcanic eruptions allows time for evacuation, reducing injuries and deaths. Planning avoids development in high risk areas and prepares emergency responses. Building techniques can strengthen structures against ash or divert lava. Educating the public about evacuation and survival kits helps people get to safety. International aid for poorer countries lessens eruption impacts like hunger.

Reducing the Impacts of Volcanoes Prediction 1) Unlike earthquakes, it’s possible to roughly predict when a volcanic eruption will happen. Scientists can monitor the tell-tale signs that come before a volcanic eruption. 2) Things such as tiny earthquakes, escaping gas, and changes in the shape of the volcano (e.g. bulges in the land where magma has built up under it) all mean an eruption is likely. 3) Predicting when a volcano is going to erupt gives people time to evacuate – the reduces the number of injuries and deaths. Planning 1) Future developments e.g. new houses, can be planned to avoid the areas most at risk from volcanic eruptions. This reduces the number of buildings destroyed by an eruption. 2) Firebreaks can be made to reduce the spread of fires 3) Emergency services can trains and prepare for disasters, e.g. by practicing setting up emergency camps for homeless people. This reduces the number of people killed. 4) Governments can plan evacuation routes to get people away from the volcano quickly and safely. This reduces the number of people injured or killed by things like pyroclastic flows or mudflows Building techniques 1) Buildings can’t be designed to withstand lava flows or pyroclastic flows, but they can be strengthened so that they’re less likely to collapse under the weight of falling ash. 2) The lava from some volcanoes can be diverted away from buildings using barriers. 3) Both of these reduce the number of buildings destroyed, so fewer people will be killed, injured, made homeless and made unemployed. Education 1) Governments and other organizations can educate people about how to evacuate if a volcano erupts. This helps people to get out of danger quickly and safely, which reduces deaths. 2) People can be told how to make a survival kit containing things like food, water, a torch, a radio, batteries and
dust masks. The kit reduces the chance of people dying if they’re stuck in the area. Aid 1) Poorer countries that have been affected by a volcanic eruption can receive aid from governments or organizations – it can be things like food, water, money or people (e.g. doctors). 2) Aid helps to reduce the impacts, e.g. food aid stops people from going hungry.
