Japan: Mount Meakan in Hokkaido is passed from the warning level 1 to level 2 after a field survey which found an increase in volcanic activity through increased fumaroles with a the rise in temperature near the craters and a significant increase in shallow earthquakes!
The swarm follows a gradual increase in seismicity under the volcano noted since April this year. JMA thinks the most likely outcome is a very small (phreatic) eruption in the near future and recommends not to approach the crater within 500 m.
