Modern technology and a long history of increasing knowledge about
volcanoes, have helped
to forecast volcanic eruptions today, and to get people away from
the area in time.
Let us take a few examples, that shows that it is not the eruption
itself that is so dangerous,
but it is what people do - or do not - after an eruption.
