The submarine eruption at El Hierro continues at low levels with no significant changes. The stain of the ocean above the vent(s) remains strong, and occasionally, smoking lava balloons are seen rising. ...more [read all]
Sporadic strombolian eruptions continue from the New SE crater of Etna, but - in contrast to previous such episodes - no new paroxysm has yet occurred. The volcanic tremor shows a slightly increasing trend with more fluctuations than normally. ...more [read all]
Mt Cameroon volcano in Cameroon seems to have started a new eruption. According to local news, mild tremors and explosions were noted at the volcano during the past week, intensifying last Friday.

 Seismicity in Iceland during the past 2 days (Icelandic Met Office)
Tungurahua volcano (Ecuador) produced a sudden strong ash explosion yesterday (4 Feb 2012) morning at 05:50 local time, following an increase in seismic activity recorded since around 04:30. The eruption lasted about 5 minutes and produced a plume rising to about 7-8 km altitude and drifting NE and later SE. Ash fall occurred in Baños, Juive, Runtún, Pillate, San Juan and Cotaló. ...more [read all]

Cleveland Volcano (Aleutian Islands) is showing renewed activity, which was observed in satellite data, and AVO is raising the Aviation Color Code to Orange and the Alert Level to Watch. A new lava dome has been observed in the summit crater, and as of 30 January 2012 was approximately 40 meters (130 feet) in diameter. There have been no observations of ash emissions or explosive activity during this current lava eruption. ...more [read all]

The swarm of earthquakes in the Cretan Sea 50 km SW of Santorini seems to be decreasing. Talking with Dr. Athanassios Ganas, head of the Athens Geodynamic Institute, and others, there is a consensus that the quakes are tectonic in origin and not related to volcanic activity (after all, their location is far from the Santorini volcanic system).

The seismic swarm 50 km SW of Santorini continues with a smaller number of quakes than in the first 2 days. 10 Quakes were recorded in the past 24 hours, including a 3.9 magnitude last night at 31 km depth at 22h46:33 GMT. Interestingly, no quakes seem to occur inside the caldera or in the immediate vicinity of Santorini since the swarm to the SW has started. This clearly shows that there is some relationship. What nature this has, is speculation. ...more [read all]

A 5.3 magnitude earthquake hit about 50 km SW of Santorini on 26 Jan at 04:24:58 GMT. The quake was 28.7 km and most likely of tectonic origin. The location is 48 km SW of Santorini at the end of a tectonic fault defining a graben SE of Santorini and the eastern boundary of the volcanically active SW-NE zone comprising the volcanic vents of the Christiania Islands, Santorini itself, the submarine Kolumbos volcano and several minor submarine vents NE of Kolumbo.

 The earthquakes of 26 January 2012 on the central fault system of Santorini
Since Monday 23 January 2012, there has been an intensification of Sangay volcano's activity, as indicated by reports from pilots who reported the presence of ash from the volcano drifting S-SE. In addition, satellite images from 24 Jan show the presence of thermal anomalies at the volcano. ...more [read all]

The Hawaiian Volcano Observatory today celebrates 100 continuous years of monitoring at Kīlauea volcano with a Public Open House -- only Vesuvius has a longer record, dating back to 1841! In fact the first scientific monitoring in Hawai'i was conducted in 1911 by Frank Perret, an Honorary Assistant to the Vesuvius Observatory, in preparation for Thomas Jaggar to establish HVO in 1912. They are hosting many activities today in celebration, if you are in the Kīlauea area! ...more [read all]

 Bathymetry of the new submarine cone
Thursday, Jan 19, 2012
Since yesterday, the activity at the El Hierro submarine volcano had been increasing, which could be seen on the harmonic tremor signal and the active jacuzzi above the vent on the ocean surface. The activity included strong bursts of harmonic tremor thought to be caused by hydromagmatic (magma-water) explosions. ...more [read all]
IG reported a new episode of activity and increased seismicity from Tungurahua during 11-17 January. On 12 January ashfall was reported in Manzano (8 km SW), Cahuají (8 km SW), and Choglontus (13 km WSW). ...more [read all]
Fuego volcano produced explosions observed on 11-13 and on 16 January, which produced ash plumes rising 400-1000 m above the crater. Shock waves and rumbling sounds accompanied the explosions and rattled windows and roofs in nearby villages. ...more [read all]
The lava dome growth of Santiaguito continues at moderate levels. Sporadic explosions produce ash clouds that rise up to 600-800 m above the lava dome and mostly drift SW. A viscous lava flow is active on the SE flank. Block avalanches are generated from the front of the lava flow and on the SW flank, accompanied by rumbling noises. [read all]

The eruption south of El Hierro is continuing, but has calmed down during the past days. In contrast to one week ago, there has been little visible surface activity at the stained area above the submarine vent near La Rrestinga. Volcanic tremor is at low, but constant levels, and indicates that lava continues to be erupted at depth. [read all]

Buenos Aires VAAC reported a pilot observing an ash plume from Callaqui at 3 km (10,000 ft) a.s.l. on 2 January. No ash could be detected on satellite images without cloud cover and it is likely that the observation was strong fumarolic activity rather than an actual eruption. [read all]
After almost a week with no accessible lava, pressure returns to Kīlauea as seen in this link's plot of ground tilt. At the same time, lava flows are again accessible via an extreme, 8-mile round-trip hike with a steep climb to private property in Royal Gardens. The hike will get easier and less dangerous once this renewed pressure pushes lava back onto the coastal flats, so stay tuned! Contact us for details on current conditions and accessibility!
