Following renewed unrest and a minor eruption beginning Aug, 2018 a significant explosion occurred at Kuchinoerabujima (Shindake) volcano on Jan 17 sending ash to 20,000ft (6km) a.s.l. and generating a pyroclastic flow, according to VolcanoDiscovery.com.
The moderate flow travelled 1.5km (~1 mile) down the southwest flank though fortunately did not affect adjacent communities.
“There have been eruptions there since last year but we sent an alert out for this latest eruption as it will have a wider impact,” said Jun Fujimatsu, an official at JMA’s volcanic activity division.
“The agency maintains a level three warning, which means a ban on entering the volcano area. The danger zone is 2 km (1.2 miles) from the Shindake crater,” Fujimatsu told AFP.
Kuchinoerabujima has a VEI 4 eruption in its recent history, occurring in Dec 1933.
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
