Asosan, the largest active volcano in Japan and one of the world's largest volcanoes, started its new eruptive phase this week prompting Japanese authorities to cancel or divert flights on Thursday, November 27, 2014.
A column of ash and smoke reached about 2 133 meters at 06:00 UTC today and was extending north, according to latest Tokyo VAAC warning. An exclusion zone of 1 km radius around the volcano is in place.
Activity from the Asosan's Nakadake crater has intensified on Tuesday, November 25 when observed ash emissions and comparably strong incandescence suggested a new magmatic eruption could be under way.
