Shinmoedake volcano, located on the Japanese island of Kyushu, erupted explosively on Wednesday 27 June, 2018 after a previous explosion that occurred 5 days before. Both eruptions produced ash plumes that are 2000 meter tall and seem to represent that aftermath of the volcano’s intense phase of explosive activity that occurred in early March 2018.

Shinmoedake is one of 18 young, small stratovolcanoes that make up what is known as the Kirishima volcano group which straddles the boundary between the Miyazaki and Kagoshima prefectures. This 1421 m tall Japanese volcano, famous for its feature in James Bond film ‘You Only Live Twice’, erupted on Wednesday 27 June, 2018, at 15h34 local time, sending a plume of ash and gas 2200 m into the air. A similar event occurred on Friday 22 June, 2018, when at 9h09 local time an explosion spewed ash and smoke up to 2,600 meters in the air. The Japan Meteorological Agency (JMA) reports that large cinders were flung up to 1,100 meters from the center of the crater rim, flying in a ballistic path, and that resulting ash plume was blown east, carrying small cinders a long way by the wind.
The 22 June explosion was the first explosive eruption since a month of increased volcanic activity ended on April 5, 2018. After 7 years of inactivity, the volcano suddenly came back to live and produced 18 violent explosions on 6 March 2018. The volcano thereby hurled rocks measuring 50 centimeters in a radius of 900 m around the vent and created an eruption plume that reached a height of about 3000 meters. This intense eruptive activity continued into March 7 when 11 more explosions were registered by JMA and the presence of red hot lava in the vent was confirmed. After this intense first phase activity died down to irregular explosions during the next couple of weeks, 1 eruption in May and now two more in late June.
The Japan Meteorological Agency (JMA) maintains the volcano alert level at 3 - restricted entry to the mountain – on a scale of 5. No evacuations were carried out, but they call on the public to exercise caution around the volcano as large chunks of debris could fall within a 3-kilometer radius of the vent, while pyroclastic flows could reach as far as 2 kilometers.
A three minute video of the entire 22 June 2018 explosion was shared on the YouTube channel of VolcanoYT’:
Japanese news paper The Mainichi obtained some great photographs of the eruption during a helicopter overflight on 6 March
