Explosive eruptions and ash venting at Shinmoedake (Kirishimayama), Japan

– March 06, 2018

The activity at Shinmoedake volcano in Kyushu, just one of 20 Quaternary volcanoes making Kirishimayama volcano group, is at elevated levels since March 5 with near-continuous ash emissions and ejections of very hot material. At 11:20 UTC today, ash column was rising 3.9 km (13 000 feet) above sea level.

This volcano roared back to life on September 7, 2017 after 6 years of quiescence, coating nearby cities and towns with a thin layer of ash.

The Japan Meteorological Agency said Kirishima erupted violently several times today and some lava was rising inside a crater.

Due to the recent activity, officials restricted access to the entire mountain, and the danger zone may be expanded to a 3-km (1.8 miles) radius from the crater.

Today’s activity, the strongest since 2011, grounded more than 80 flights at the nearby Kagoshima airport.
