The Eyjafjallajokull eruption is being considered an ongoing event. Travel insurance plans purchased before 4/13/10, for some carriers 4/15/10, are eligible for coverage. Policies purchased after the event date will not cover the volcanic ash affecting European travel. Check travel insurance carriers’ position statements on the volcanic eruption in Iceland.
Since the Eyjafjallajokull eruption is ongoing, another eruption of this volcano would be considered part of the same event. Policies sold after 4/13/10 would cover an eruption of a different volcano that is classified as a separate event.
