Volcanoes are difficult to forecast because they can cause so many different disasters themselves. Once a volcano eruption, small or large, is forecasted, you must be ready to check with your local weather television and radio stations to see what other danger the eruption will bring.

The volcanic gases that come with a volcanic explosion mixes with the ash and clouds formed by the eruption and acid rain may fall in your area.
