Volcanic activity worldwide 7 Mar 2014: Ubinas, Popocatépetl, Sakurajima, Kilauea

Sakurajima (Kyushu, Japan): Explosions have been becoming more frequent again. During the past 48 hours, VAAC Tokyo counted 8 eruptions of small to moderate size (ash plumes rising up to between 5-9,000 ft altitude).

Kilauea (Hawai'i): Nineteen earthquakes were strong enough to be located beneath Kilauea Volcano in the past 24 hours - just below average for one day!
...6 Mar:
The summit tiltmeter at Kilauea recorded a switch to DI inflationary tilt and the summit lava-lake rose several meters last night!

Popocatépetl (Central Mexico): A small explosion occurred yesterday morning, ejecting glowing material to up to 600 m distance from the crater. Otherwise, the activity at the volcano has been low, similar to previous weeks.
CENAPRED counted 14 low-intensity emissions yesterday.

Ubinas (Peru): A pilot reported a possible ash plume at flight level 290 (29,000 ft, 9 km altitude) this afternoon, which would mean a significant eruption took place. However, this needs to be confirmed yet.
IGP in its latest press release confirmed the presence of new magma in the crater. This correlates well with the detected hybrid earthquakes and bluish gas emissions, as well as the thermal hot spot visible on satellite data since mid February.
The new lava forms a flat elongated dome about 30-40 meters long.
