Volcanoes

Volcano information gathered from various sources, including the Smithsonian Weekly Volcanic Activity Report from which confirmation of reports is taken.

A volcano is only included in the listing if there is significant ash above 1km height (white/steam clouds are not counted) or there is a significant lava flow. Crater incandescence, unless accompanied by the either of the preceding does qualify as an eruption.
