When to watch

The Unzen camera points at the massif that includes Heisei-Shinzan, the peak thrown up by the eruption of the Heisei era. Lava domes collapse easily, which is precisely why the watch continues.

The Shimabara Peninsula is ringed by sea, so cloud builds readily and the summit is hidden on plenty of days. The dry air of a winter pressure pattern gives the sharpest outline.
