How Can We Stay Safe From A Volcano?

There is plenty of warning before a volcano erupts.  Days or weeks or even months can go by with signs being offered up that a volcano is about to erupt.  There may be one or more of all of these signs:  Smoke rising, small ground trembles, rumbling noises, a build up of the sides of the volcano, and now more and more,  a scientist will issue a warning that an eruption may be forthcoming.  There is plenty of time to evacuate the area around and near the volcano if only people will use their eyes & ears.  Volcanoes do not just show up over night spewing ash, lava and rocks over the land.
