Threat of powerful eruption at Kuchinoerabu volcano prompts evacuations, Japan

This volcano is located on the Kuchinoerabu Island in southwestern Japan, some 1 000 km (620 miles) SW of Tokyo. Its last eruption took place in 2015. The decision to raise the alert was made due to 26 volcanic earthquakes detected within just a few hours. The largest was M1.9 at a depth of 5 km (3.1 miles) in almost the same location as a similar pre-eruption quake that struck 3 years ago. JMA warned that eruption could be powerful enough to cause serious damage to the island's residential area. Level 4 alert means that elderly and disabled people should be evacuated and everyone else should prepare to evacuate.

The phenomenon is known as a sun dog – or parhelion – and it happens when there are hexagonal ice crystals in the air, tending to float horizontally because, in that position, they refract light so that it appears there are two other baby suns flanking the real sun. When crystals are more vertical, they create a halo around the original sun.

The phenomenon is known as a sun dog – or parhelion – and it happens when there are hexagonal ice crystals in the air, tending to float horizontally because in that position, they refract light so that it appears there are two other baby suns flanking the real sun. When crystals are more vertical, they create a halo around the original sun.  Clearly, on this day, at this exact moment, the atmosphere was alive with crystals facing both directions in the sky over Antarctica.
