MODIS hot spot data (past 2 days) for Reventador volcano (ModVolc, Univ. Hawaii)
Bagana (Bougainville Island, Papua New Guinea)
SO2 plume from Tungurahua volcano yesterday (NOAA)
: Eruptions have intensified at the volcano. Over the past 2 days, several explosions produced ash plumes rising to about 7,000 ft (2.1 km) altitude and drifting 30-45 nautical miles to the W and NW (VAAC Darwin).
Batu Tara (Sunda Islands, Indonesia)
: An explosion produced an ash plume rising to 7,000 ft (2.1 km) altitude today.
Paluweh (off Flores Island, Indonesia)
: The lava dome remains relatively active and produces frequent explosions and/or hot rock avalanches. Hot deposits from these can be seen on MODIS satellite data on the eastern, southern and western flank of the dome. Several ash plumes rising to altitudes of about 7,000 ft (2.1 km) were detected in the past days.
Papandayan (West Java)
: Increased seismic activity was detected at the volcano and VSI raised the alert level to 3 out of 4 ("Siaga", "warning") yesterday.
Sudden phreatic explosions could occur with little warning at the volcano and present a significant hazard to visitors to the crater, which is a popular tourist site due to its varied, intense hydrothermal activity and colorful active fumaroles.
Lokon-Empung (North Sulawesi, Indonesia)
: Another explosion occurred yesterday evening. It was heard in up to 6 km distance and incandescent bombs were ejected to 200 m distance from the Tompaluan crater.
The eruption was preceded by an increase in seismic activity starting Saturday night, the local volcano observatory reported.

Cleveland (Aleutian Islands, Alaska)
: After the initial explosion 2 days ago, continuous small eruptions produced a steam and ash plume yesterday and decreased in intensity again today. The activity of the volcano, which is not monitored on ground, was detected by satellite data and infrasonic tremor measured by ground-coupled airwaves on the nearby Okmok seismic network, 120 km (80 mi) to the northeast.
A faint plume extended eastward below 15,000 ft. Satellite data also continue to show highly elevated surface temperatures at the summit.

Popocatépetl (Central Mexico)
: No changes occurred in the volcano's slow effusive/explosive activity. Emissions of steam and gas, with minor ash contents, have been at rates of less than 1 per hour during the previous days, but continuing lava glow can be seen from the summit.
Santa María / Santiaguito (Guatemala)
: The lava dome has remained relatively calm recently with few and mostly weak explosions every now and then, and little activity from the blocky lava flows on the flanks of the Caliente dome.
: Weak strombolian activity probably continues. It can not always be observed, but only heard and shows on the seismic recording.
: Activity remained at low level, characterized by few (6 during yesterday) strombolian-type explosions that produce gray ash plumes rising 300-500 m above the crater.
Nevado del Ruiz (Colombia)
: After a short pause, a new seismic swarm, possibly indicating yet another pulse of magma intrusion, started yesterday at the volcano. The largest quake was a magnitude 2.9 event at 19:28 local time at 5.4 km depth beneath the Arenas crater. It was felt around the volcano.
: Activity has remained moderate with occasional explosions and possibly the emplacement of a hot avalanche or lava flow on the eastern flank, where a new hot spot on the latest MODIS satellite data can be seen, in addition to the summit where a lava dome is active.
: A gradual increase in eruptive activity is evident. Near continuous ash and steam emissions are interrupted by cannon-like explosions that produce ash plumes rising up to 2-3 km height and produce light ash falls in the areas around the volcano. At night, strombolian activity can be seen from the summit.
A significant SO2 plume can be seen on satellite data drifting to the NW.

Cleveland (Aleutian Islands, Alaska)
: A possible explosion occurred this morning at the volcano at 5:00AM AKDT (13:00 UTC) by AVO infrasound recorders. The infrasound signals suggest that this was a relatively short duration, low-level explosion. No eruption cloud has been detected in available satellite views. AVO received no other reports of activity. (USGS / AVO) ...

Sakurajima (Kyushu, Japan)
: Since 1 May, activity has been increasing again from relatively low levels during the weeks before. Over the past 3 days, several explosions have produced ash plumes rising to 10,000 ft (3 km) altitude and on most days, there have been 3-4 daily explosions (for Sakurajima, this is a large number). ...

Stromboli (Eolian Islands, Italy)
: Lava continues to intermittently flow over and out of vents at the rim and the base of the NE crater. Yesterday, the active flow front had reached about half way down the Sciara, local guides reported. ...

Stromboli (Eolian Islands, Italy)
: After decreasing a bit yesterday, the overflow of lava from the NE vents has gained in strength this morning again, accompanied by constant rockfalls, relatively strong explosions and higher tremor. ...
Tuesday, Apr 30, 2013
: The famous Icelandic volcano is showing further signs that indicate an eruption could occur in a near future. Significant rapid inflation, concentrated in the northern part of the volcano, has been detected since early April and likely represents accumulation of rising magma underneath. ...
