Wouldn’t it be nice to be able to forecast major eruptions? So far, the opportunity has been lacking. VEI-7 eruptions are rare: we have not seen one since Tambora in April 1815. To make a right ...

Like other natural disasters, volcanic eruptions can have an impact on civilizations. Of course they can annihilate them, but they can also contribute to their economic development by providing a ...

The current Decade Volcano Program First of all, let me make one thing abundantly clear. This is a list put forth by us as suggestion for a new Decade Volcano program. But, in the end it is the ...
