Mount Sakurajima A volcano erupted in southern Japan on Wednesday, blowing ash about 3,000 feet into the air, the Weather Agency said. There were no immediate reports of damage or injuries. Mount Sakurajima erupted at 5:30 p.m. and registered as moderate on the agency’s scale for both the sound and strength of the tremors it caused, the agency said. That’s a lot of ash. Seems to be a big year for volcanic activity so far. Wonder how much this is affecting global cooling?
