SeasonMap

Volcanic activity, month by month around the world

Eruption alerts, ash clouds and closed summits — irregular, but the place plans around it.

This is a warning page, not a recommendation. Volcanic activity covers 14 destinations on SeasonMap; the months below are the ones in which the risk window is open — most weeks in them pass quietly, and the score beside each place is still the ordinary climate score, hazard and all.
