Asama, Sakurajima and Karymsky all erupt while Redoubt doesn't

Mt. Asama near Tokyo did, in fact, erupt within the "two day" window predicted by the Meteorological Agency of Japan. The reports this morning put the ash column at ~2,000 meters (~6-7,000 feet), so relatively small, but big enough to dust parts of Tokyo (~145 km away) with ash. No evacuations are planned for the area around Asama, but people who live within 4 km of the volcano are to "take caution". 

There are also new reports that Mt. Sakurajima in southern Japan erupted yesterday. Block were thrown up to a few kilometers from the volcano. The article suggests that ash spread as far as the Philippines and Vietnam, but I have yet to find any other data to back this up. The same article also mentions that Karymsky erupted overnight as well. The impression I get is that they got all this information from the Tokyo VAAC when they were researching the Asama eruption, so few details beyond "ash" can be found.

Of course, with all these other volcanoes picking up the slack, Redoubt remains recalcitrant in its activity. There was no eruption over the weekend and the latest AVO has to offer is the news of an intense jolt to the volcano early this morning, but no eruption thus far today.

Mt. Redoubt in March 2009, prior to erupting At ~10:30 PM (Alaskan Time) last night, Mt. Redoubt erupted. AVO and the Anchorage VAAC issued a Red Alert for ash as high as 50,000 feet (15,000 meters) around the volcano. Information is scarce about the exact nature of the ash cloud because of the…

Hey, Recoubt is an American volcano - give it a break, it's still recovering from the Superbowl. Did you expect it to work on the weekend? ;-)

I'm living in Kagoshima next to Sakurajima, and haven't seen any Japanese reports that ash has reached the Philippines or Vietnam. Very dubious. Explosions intensified last week, but nothing to report over the weekend.
P.S. As a regular viewer of your great blog, it's nice to see some coverage of Japan! Keep up the good work!
