Moderately large eruptions have occurred at Mt. Sakurajima volcano in southern Kyushu, Japan. During the past few days, several vulcanian-type explosions took place that ejected large amounts of bombs, with some of 50 cm diameter landing in up to 2 km distance. Ash plumes produced reached a modest altitude of 8000 ft (ca. 2.5 km) (VAAC Tokyo).
According to various news agencies quoting the Japanese Meteorological Agency an eruption that was videotaped on Monday was "the largest since 2009". This statement appears a somehow questionable, because the activity rather looks like more than slightly more than average activity....Click volcanodiscovery.com

The sun unleashed a new solar flare Tuesday (March 13) from the same region that has been actively brewing for the past week.
The flare was categorized as an M7.9-class eruption and peaked at 1:41 p.m. EDT (1741 GMT) on Tuesday. While the outburst hurled a wave of plasma and energetic particles, called a coronal mass ejection (CME), into space, it is not heading in Earth's direction, according to solar physicists at the federal government's Space Weather Prediction Center, which is managed by the National Oceanic and Atmospheric Administration and the National Weather Service.
"The Solar Radiation Storm promptly reached S2 (Moderate) levels, but now should slowly decline," experts at the Space Weather Prediction Center said in a statement. "A CME also occurred that appears to be on a path not towards Earth."
Yesterday's flare is the latest in a string of eruptions from a giant sunspot region called AR 1429, which has been particularly active lately. This sunspot region has already unleashed three strong X-class solar flares and several weaker M-class eruptions. Last week, X-class flares from region 1429 triggered the strongest solar storm in eight years...Click Space.com link for more
