Unzendake (Complex) Β· last erupted 1996
Tectonic setting: Subduction zone / Continental crust (> 25 km)
The massive Unzendake volcanic complex comprises much of the Shimabara Peninsula east of the city of Nagasaki. An E-W graben, 30-40 km long, extends across the peninsula. Three large stratovolcanoes with complex structures, Kinugasa on the north, Fugen-dake at the east-center, and Kusenbu on the south, form topographic highs on the broad peninsula. Fugendake and Mayuyama volcanoes in the east-centβ¦

Current GOES X-ray flux class
Solar wind speed and magnetic field strength indicate current space weather activity. Elevated or storm-level readings can disrupt satellites, GPS accuracy, and power grids. This is a planetary-scale signal, not specific to this location β typical quiet conditions run under 400 km/s wind speed and under 5 nT magnetic field.
