Volcano Shinmoedake Eruption Activity Continued. Plume Height 300 Meters, Japan

On Miyazaki, Kagoshima prefecture border Kirishima Mountain · Shinmoedake (1421 m) eruption continued for two days. According to the Meteorological Agency, in the morning I observed that the plume was rising from the crater to about 300 meters high. The agency maintains an eruption warning level 3 (entry restriction) and continues to call for vigilance.

Cleveland Volcano, Alaska Alert Level Raised To ORANGE

A small explosion was detected yesterday at 14:57 UTC (05:57 AKST) on seismic and infrasound sensors. A small ash plume was observed heading ENE at an altitude of about 15,000 ft (5 km). 
The Alaska Volcano Observatory (AVO) raised the aviation alert level of the volcano to Orange
“Explosions from Cleveland typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible. 
Cleveland volcano is monitored with a limited real-time seismic network, which inhibits AVO’s ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.”
