Etna volcano (Italy), activity update: new fissure eruption near SE crater

From field observations by Rosario, the beginning of a large new eruption at Etna is confirmed. Following the intense tremor, a fissure has opened NE of the SE crater, about 800m long, and erupting from about 15 vents with spectacular bubbles and hawaiian lava fountains. The lava is very fluid and f...

From field observations by Rosario, the beginning of a large new eruption at Etna is confirmed. Following the intense tremor, a fissure has opened NE of the SE crater, about 800m long, and erupting from about 15 vents with spectacular bubbles and hawaiian lava fountains. The lava is very fluid and forms impressive flows into the Valle del Bove.
Ash fall has covered the area of Randazzo by about 1 cm. Still as a result of the brief violent precursor eruption from SE crater on May 10, the airport of Catania is closed. Access to the moutain has been closed at 1200 m on all roads. The bad weather at present does not allow detailed information. We are on our way to Etna to report more in the following days.

The new eruption phase of Etna volcano shows high seismic activity and ash clouds caused the airport of Catania to be closed. Our team member Marco Fulle is reporting high seismic activity that may cause a new fisure to be opened at Etna volcano.

Our VolcanoDiscovery Team members Marco Fulle and Rossario Basile report new paroximal eruptions at the SEC area of Etna volcano and a lava flow into the Valle del Bove. Because of bad weather conditions no more details can be reported yet.

As observed during our recent tour to Etna and the Eolian Islands, mild strombolian activity, with small exploisions every 10-20 minutes, is present at the vent located at the lower E flank of the SE crater of Etna.

Based on pilot observations, the Darwin VAAC reported that a plume from Semeru rose vertically to an altitude of 6.1 km (20,000 ft) a.s.l. on 21 April.

Anak Krakatau is getting active again. CVGHM reported increased seismicity during 14-21 April as well as ash plumes accompanied by ejections of incandescent rocks observed during field observations on 16, 17, and 18 April. The renewed eruption affected the summit and the E and S flanks. Booming noises were reported and occasionally heard at an observation post 42 km away. The Alert Level was raised to 3 (on a scale of 1-4) on 21 April.

Glow from the Halemaumau vent (17 April, 2008)
Glow from the Halemaumau vent (17 April, 2008)

Kilauea continues to be active at two locations: At the summit, ash elevated sulfur dioxide emissions continue from the Halema`uma`u vent, accompanied by elevated levels of seismic tremor. At the east rift eruption site, lava is flowing through lava tubes and entering the ocean at the Waikupanaha entries.

A large active submarine volcano has been found off the Reykjanes peninsula in Iceland near the capital Reykjavik. Volcanologist Ármann Höskuldsson from the University of Iceland and a team of scientists who have been conducting research on the volcano told in a recent press release that the volcano who has now been quiet for at least 100 year, cold well erupt in some not too distant future.
The volcano is located at 1500 m below sea level and has a summit caldera measuring 10 kilometers in diameter. The great depth of its location makes it unlikely that eruptions would have major effect on Iceland's mainland, except perhaps causing earthquakes.
According to the press article, the researchers plan in 2009 to use a small submarine to undertake more detailed research of the underwater volcano.

Over the past three weeks, Lengai has quietened down significantly. Observers report a complete pause in activity lasting about two weeks, and then resuming of relatively small ash eruptions. A thermal anomaly is still visibile on satellite date in the crater of the ash cone.

There are no significant changes at Kilauea volcano, which is active from two locations: at the summit, the new vent in Halema`uma`u crater continues to erupt ash and emit elevated lamounts of sulfur dioxide, accompanied by higher levels of volcanic tremor. At the coast, lava continues to flow into the ocean at the Waikupanaha and Ki ocean entries.

The ash plume from the new Halemau'uma'u vent.
The ash plume from the new Halemau'uma'u vent.

The new gas vent at Halema`uma`u crater has erupted lava the evening of Easter Sunday into early Easter Monday. The amount of lava erupted from the vent last night was small, but it represents the first lava erupted from anywhere in Halema`uma`u since 1982. Previous eruptions included lava flowing into the crater from fissure eruptions on its southwest rim in 1974 and 1971 and an 8 month eruption in Halema`uma`u in 1967-1968 that created a lake of lava that covered the entire crater floor.
At the moment, the vent erupts a plume of gas and fine ash particles rising to 1-1.5 km above the crater. Aviation agencies have been notified by the potentially hazarous conditions flying near the plume.

On March 19, 2008, a small explosion occurred at Halema'uma'u Crater at the summit of Kīlauea Volcano. This is the first explosive event at the summit of Kilauea after almost a century.
A more detailed press release about this unusual event sent out by HVO can be found reproduced at this page.

While lava continues to flow into the ocean, an unusual event is taking place at the summit of the volcano: a new gas vent has opened at the base of Halemaumau crater in the caldera of Kilauea volcano.
Here is some additional information released by HVO:
 
A prominent new gas vent broke through the lower east wall of Halema`uma`u
crater on March 12, 2008, doubling the already elevated level of sulfur
dioxide gas being emitted from the crater. The vent was obviously
incandescent by evening of the next day.
Release of sulfur dioxide gas from Kilauea volcano is not new, but the
current emission rates are unusual. Gas emissions have been unsettled
since June 2007 but the root cause of the recent increase in SO2 emissions
from Halema`uma`u crater is not yet clear.
While it is a remote possibility, a summit eruption is not expected
because the summit is deflating and not experiencing an unusual number of
earthquakes.

Lengai's activity has been continuing to increase. Over the past days, several ash eruptions have produced plumes up to more than 10km height, the largest one possibly being on 4 March rising to about 14 km, as evident from satellite data, observations by passing aircraft and spectacular photos taken from the ground posted on Fred Belton's website.
Possibly, some of the eruptions have also produced pyroclastic flows travelling part way down the steel flanks of the mountain. It should be noted that visiting Lengai, even its lower flanks must be considered EXTREMELY dangerous. There are no safe observation spots nearby, particularly as the topography of the mountain puts the surrounding flat areas into a high risk zone of pyroclastic flows.

Based on satellite imagery and information from RVO, Bagana volcano has been producing small ash explosions since 3 March.

IG reported steam and ash-and-steam plumes from Tungurahua that rose to altitudes of 5.8-8 km (19,000-26,200 ft) a.s.l. during 27 February - 1 March. Ash plumes drifted NW, W, SW, and SE, ashfall was reported in areas to the SW on 27 February. Lahars or mudflows descended the Mapayacu and Choglontus drainages in the SW, and drainages in the Pampas sector to the S on 27 and 28 February.
 
Shiveluch volcano continues to produce small hot avalanches from its growing lava dome. Based on seismic interpretation from KVERT, ash plumes possibly rose to an altitude of 5.6 km (18,400 ft) a.s.l. during 24-26 February.

During 13-19 February lava-dome growth at Mount St. Helens continued.
Seismicity persisted at low levels.
During 13-19 February the lava dome at Soufrière Hills changed very little. Seismic activity was very low and low-level rockfall activity continued. Fumarolic activity on the N and E flanks continued. Active fumaroles were also noted in the Galway's area to the S of the dome.
Heavy rainfall triggered lahars in multiple drainages. The Alert Level remained elevated at 4 (on a scale of 0-5).
