Asama (Honshu): (12 Jun) The Japan Meteorological Agency (JMA) raised the alert of the volcano from 1 to 2 (on a scale of 1-5), as the volcano has recently been showing growing signs of unrest - increased seismic activity and strongly elevated gas emissions.
Seismicity started to show a weak upward trend already in early 2014, but then stagnated until past April, when the number of daily,and relatively shallow (2-3 km depth) earthquakes detected rose to over 80, the highest level since the volcano had quieted down after its last eruption in 2009.

Sinabung (Sumatra, Indonesia): (12 Jun) The lava dome at the volcano's summit continues to grow at a rate of approx 100,000 cubic meters per day. Small to moderate pyroclastic flows during the past week have mostly removed the viscous lobe on the upper southeast flank.
As lava continues to accumulate at the dome itself, more pyroclastic flows are likely to occur in the near future. Authorities are considering extending the exclusion zone in the southern sector.
