Mt Fuji volcano (Japan): signs of volcanic unrest reported

Reports are appearing about unrest and signs of a possible awakening of Mt Fuji volcano in Japan. 

According to a report which includes an unclear photo of the area, a row of new craters, the largest 50 m in diameter, has appeared on the eastern flank of the volcano at 2200 m elevation. Steam was observed erupting from these vents. 

The observation joins other signs suggesting a gradual reawakening: A swarm of earthquakes including 4 of magnitude 5 have occurred northeast of Mt Fuji on and after 28 January. An earlier 6.4M quake occurred under the volcano on 15 March 2011. The report also mentions increased activity from a fumarole vent at 1500 m elevation and hot spring areas at the eastern flank observed since 2003.
