Sample of the White Lava erupted during the 16 Mar paroxysm (OPEC)
Etna volcano might have begun a process of deep transformation in its eruption style, new scientific studies suggest. ...plus [lire toutes]
dim., 31 mars 2013, 19:04
Current view of Etna (INGV webcam)
Etna (Sicily, Italy): At the surface, Etna remains calm. The current seismic signal and tremor values at the moment don't suggest a new paroxysm from the New SE crater is be expected very soon (although some paroxysms have shown build-up phases of less than a few hours only). ...plus [lire toutes]
dim., 31 mars 2013, 12:10
Current seismic signal from Reventador (CONE station, IG)
IG observed a steam column rising 700 m yesterday and glow at night from the summit, indicating that weak effusive activity continues there. ...plus
dim., 31 mars 2013, 12:05
Current seismic signal from Tungurahua (RETU station, IG)
Seismic activity, including volcanic-tectonic and long period earthquakes have increased in number and magnitudes during the past 2 days, suggesting new magma might have started to rise within the volcano and could herald a new phase of explosive activity soon. ...plus
dim., 31 mars 2013, 11:56
A strong magnitude 4.9 earthquake has occurred at 11:00 GMT west of El Hierro at 20 km depth. This is so far the by far strongest quake during the seismic crisis.
dim., 31 mars 2013, 11:14
Current seismic signal at Masaya (MASN station, INETER)
Periods of elevated volcanic tremor continue to appear regularly at the volcano. At the moment, seismic activity is again relatively calm.
dim., 31 mars 2013, 10:53
Location of yesterday's 3.8 earthquake
Some felt earthquakes have occurred recently along the southern boundary of Long Valley Caldera, the latest a 3.8 magnitude quakes yesterday. This is not unusual for the volcanic system and does not mean any volcanic eruption should be expected in a near future. The alert status remains green (normal).

Current seismogram from Telica volcano (TELN station INETER)
The earthquake swarm still continues, accompanied by near continuous tremor, although at reduced intensity.
dim., 31 mars 2013, 10:37
Santiaguito and Santa Maria on a clear morning yesterday
Activity has remained weak. Only few small explosions occurred from the dome and the block lava flows on the flanks of the dome showed little movement recently, in the form of small avalanches from their steep fronts. ...plus
dim., 31 mars 2013, 10:33
Typical explosion from Fuego yesterday
Activity has remained stable, with occasional strombolian explosions ejecting glowing lava bombs to about 100 m height above the crater. Ash plumes rose 600-800 m and drifted about 10 km into southerly directions. ...plus
