Intermittent small phreatomagmatic (magma-water interaction) explosions with typical cock-tail emissions of dark ash and blocks, followed by steam trails continue to occur from crater 1. Access to Nakadake remains restricted.
Hakone (Honshu): Unrest at the Owakudani valley continues. Fumarolic activity has increased drastically. Ground has lifted by up to 15 cm during 7-21 May, or up to 20 cm when compared to early October last year.
Sakurajima (Kyushu, Japan): A peak of activity occurred yesterday, with two strong explosions that produced ash plums that rose to 17,000 ft / 5 km altitude.
The activity was followed by continues, noisy smaller explosions and ash venting which lasted and slowly decreased during the night.
Today, two normal-sized explosions have taken place so far.
Batu Tara (Sunda Islands, Indonesia): The volcano had explosions that produced ash plumes that rose to 8,000 ft (2.4 km) altitude and drifted 80 km to the west today.
Lokon-Empung (North Sulawesi, Indonesia): An explosion occurred Wednesday (20 May) at 15:22 local time and produced an ash plume of approx 1.5 km height. The eruption was accompanied by strong explosion sounds, that caused concern in nearby villages and the town of Tomohon. After the initial explosion, mild ash venting continued for a while.

Fuego (Guatemala): Activity at the volcano has increased during the past days. Strombolian explosions have been small, moderate and large and occurring frequently. Ash plumes rose to 1 km above the crater and incandescent jets 150 m above the crater.
Most explosions generated shock waves and locomotive-like degassing sounds. Ash fall occurred in areas to the W and SW, in the villages of Morelia, Panimache, Sangre de Cristo.
Telica (Nicaragua): Several new explosions occurred during the past days, some of which showered the volcano's summit cone with incandescent material.
Chaitén (Southern Chile and Argentina): The alert level of the volcano was raised to "yellow", after an increase in seismic activity was detected.
Chaitén had a famous catastrophic plinian eruption in 2008, which followed centuries of quiescence and ended in the construction of a new lava dome.
Piton de la Fournaise (La Réunion): The eruption continues with stable lava effusion accompanied by stable tremor levels since Monday. Lava fountaining at the vent reaches up to 40 m height and the lava flow continues to move slowly towards the coast, from where it was still 3 km distant yesterday evening.
