Since 12:40 UTC, a strong tremor signal and many stronger quakes have been recorded. A series of about 10 strong volcanic quakes occurred between about 13:00-13:10.

More than 2 months have passed since the last SE crater paroxysm and Etna has been very quiet lately. Last night, the tremor signal started to rise sharply, as typical during the onsets of the past paroxysm, but then dropped again, took another rise, and dropped back again.

Live data viewed with our webcams.volcanodiscovery.com tool
The intense seismic swarm at El Hierro volcano continues with more than 100 quakes > M1.5 so far today. The quakes are concentrated underneath the El Julan coast, and some of the most recent quakes today have been at significantly shallower levels, 15-17 km, and indicate that magma now has started to rise. ...plus [lire toutes]

Seismic activity at Galeras volcano 28 June 2012
Tremor and small earthquakes continue to occur at Galeras volcano. Some of the seismic signals (such as the one early on 28 June) look like screw-shaped tornillos, which in the past have often preceded eruptions. ...plus [lire toutes]

Earthquakes are still at 20 km depth and continue at high rate (more than 150 >M1.5 today, mostly larger than M2). Accompanied by harmonic tremor, their location is migrating southwards into the Las Calmas Sea. In other words, magma continues to move southwards and the question is whether or not it will at some point start rising to the surface.

SO2 plume from Popocatépetl (NOAA)
Small volcano-tectonic earthquakes, spasmodic and harmonic tremor, along with small gas and ash emissions, and occasional explosions continue. ...plus

Seismic recording from Pacaya volcano (INSIVUMEH)
Pacaya volcano shows frequent quakes and tremor episodes, but there is only steaming as visible activity.
mer., 27 juin 2012, 09:19
A moderate explosion occurred at 05:47 26 June producing a 600 m tall ash column drifting SE, and causing ash fall in the areas of Finca San José and Finca La Quina. Weak avalanches descended from the SE side of the dome and the lava flow front on its SW side. After 21:00 at night, a small lahar descended into the Nimá I river.
