Yesterday, IGN listed 63 earthquakes, 4 above or equal to 3, 27 in between 2 and 3 and 32 lower than 2. The strongest was a M3.3 quake at 14:16 UTC. Today, Saturday IGN has listed already 32 earthquake, the vast majority with epicenter in the El Golfo area. The tremor of 10:46 UTC this morning was the strongest at M 3.3.
It is likely that this is related to magma movements at depth, but at present not a sign that another eruption or a major change in the eruption style could be in the making. However, the situation clearly needs to be followed carefully. [less]

In the meanwhile, the eruption continues and produces a large stain of discolored muddy water drifting around the southern and western coast of El Hierro. [less]

The authorities are distributing face masks to the population to protect from breathing ash. So far, 128 persons are reported evacuated, while 4 persons refused to leave their homes. More evacuations in a radius of 45 km around the volcano are planned, and the highest alert has been declared for the communities of Aysén, Río Ibáñez and Chile Chico and the Región de Aysén region.
Compared to previous days, seismicity has decreased, Enrique Valdivieso, the director of SERNAGEOMIN told the El Diario de Aysen newspaper. A major concern remains the threat of lahars (mud flows), likely to affect the Río Sorpresa valley. [less]

The Chilean government has already evacuated over 100 residents living within 25 miles of the Hudson volcano.
Eruptions of Hudson volcano are typically highly explosive and although the area is sparsely populated, pose a serious risk of pyroclastic flows, ash falls, and mud flows generated by melting of the ice and snow present on the slopes of the massive volcano. The last eruption in 1991 was Chile's second largest in the 20th century. [less]

This eruption comes more than 15 days after the previous one on 8 Oct, which marks the longest so far interval between paroxysms, and might be a sign of exhaustion of the magma reservoir and the dynamics feeding this exceptional serious of eruptions. [less]

Above the vents, large plumes of discolored water are visible and can be detected even on satellite images from space. A strong odour of sulfur can be detected on land.
The port town of La Restinga has been evacuated and ships and aircraft are now banned from the area. Unless the eruption proceeds to shallower levels from about less than 50-60 m water depth, either by the accumulation of volcanic material above the vents, or by a upward propagation of the eruption fissure towards the coast, it is unlikely that the activity will become dangerous for the coastal areas. Should the eruption proceed to shallower levels, however, the risk of explosive eruptions increases drastically as the water pressure to contain explosions becomes too low. [less]

In the meanwhile, there is little doubt that a submarine eruption is in progress 5 km off shore south of El Hierro. Due to the depth of the eruption at 600 m below the surface, there is not visible activity for now, but the intensity and location of volcanic tremor and the sighting of lots of dead fish above the spot are speaking a clear language.

"As you may know Krakatau have seen a huge increase of Volcanic quakes, shallow earthquakes. Before the earthquake swarm started (before Sep 30) the rate was around 80-200 per day. When I visited the observatory the rate was around 5000, even 6000 this sunday. The people at the observatory claim they have never seen a rate like this from Krakatau, and question themselves what will come? On sunday they went to Krakatau to position two more seismograph to get more clearer data to work on.
Im really intrested in the subject, and I have posted a video of of the seismograph taken on saturday 8th october. See it here. [less]

Tom Pfeiffer and his group of VolcanoDiscovery's Stromboli to Etna tour were lucky to be able to witness the eruption from close range. The activity started a slow gradual increase of volcanic tremor visible since around 9am, and with increasing and noisy strombolian explosions from one and later several vents inside the crater fissure of the New SE cone at around 1h00 pm; a lava flow emerged from the narrow SE directed channel aroud 3 pm, accompanied by a row of low liquid lava fountains just outside the gap of the crater, aligned on the SE trending fissure dividing it.
Heavy fog, hail, very cold temperatures and strong winds prohibited detailed observations of the main phase of the eruption between ca. 3 and 4 pm, when taller lava fountains could be heard. A dense column of ash was sometimes seen rising above the clouds and drifting east. The eruption was over by around 5pm, by which time, the summit area again cleared. By then, the lava flow had descended the steep wall of the Valle del Bove and reached its base. [less]

The eruption followed an unusual seismic crises that had started 30 Sep and produced more than 5700 quakes recorded in a few days.
If you're interested in an expedition to Krakatau to have a look at this new eruptive phase, please contact us, or simply leave a facebook comment below. [less]

Bad visibility due to clouds and rain prevented detailed observations, but the activity started slowly during the afternoon, with exponentially rising levels of volcanic tremor, ash emissions and increasing strombolian activity originating from probably several vents inside the new crater.
The eruption culminated in a brief (1 hour approx) phase of lava fountaining around 9-10 pm, and produced large lava flows towards the E and ESE into the Valle del Bove. The eruption was over at around 11pm, after a peak between around 9-10pm. This marks #15 in the series of powerful eruptions of the New SE crater in 2011, and followed the previous one on 19 SSep after an interval of 9 days. [less]

Local authorities advised some local residents to evacuate from their homes, shut El Hierro’s main tunnel, and closed local schools.
According to news, plans are being made to be ready to evacuate more of the island’s 10,000 residents and 2 units of the Spanish military’s emergency intervention unit (EMU) has arrived from nearby island Tenerife to assist in the possible evacuation of hundreds of El Hierro residents. [less]

Öraefajökull volcano only erupted twice in the past 100 years, in 1362 and 1727-28, but both eruptions were highly explosive and devastating. In particular the 1362 eruption devastated a whole region, which was later called "Öraefi", which means "wasteland".
The current activity is not necessarily meaning that a new eruption will happen, but as geophysicist Ari Trausti Gudmundsson said in an interview, such activity under Öraefajökull is rare, and clearly needs to be monitored. [less]

The affected area is about 80 m long, located in the northern part of the 1953-55 lava dome next to the crater lake and focused around 2 fissures, which have been growing recently. The area is the same as the origin of the phreatic explosions during the past 2 years. A similar period of incandescence of the dome occurred in 1981. [less]

Paroxysm nr 14 thus follows almost exactly 11 days after the previous, confirming the steady increase of invervals between eruptions from 6,7,8,9,10, and now 11 days. Will the next eruption then occur on 19 Sep + 12 days = 1 October? We will see (... by coincidence our next tour in Sicily starts on Etna on 1 October!). [less]

The NE crater (towards Stromboli Village and well visible from along the Sciara del Fuoco) is still showing impressive explosions of liquid lava bubbles every 15-30 minutes, with explosions typically reaching 100-200 m height, showering the outer flanks of the cone with glowing bombs, many of which then roll down the Sciara into the sea.
At least 2 other vents in the central and NW crater area also display strombolian eruptions of similar intensity at slightly longer intervals. Only weak spattering occurs from time to time from the NW cone. [less]

In the crater itself, up to 10 active vents were reported to be visibe by people who had a chance to visit Pizzo briefly during periods when excursions were possible.
During our stay on 9 September, in addition to the spectacular activity of the NE crater, the steep cone active in the NW part of the crater terrace was observed to erupt constantly with pulsating strombolian bursts reaching 50-150 m. The central crater vent erupted at "normal" intensity roughly every hour. [less]

During the eruption, the eastern half of the south wall of the crater collapsed, leaving an impressive array of blocks and a steep spine standing in the collapse area. Lava flows generated in the eruption partly went through the breach and passed only a few 100 m north of Belvedere and descended into the Valle del Bove. [less]

Lewotobi is one of the most active volcanoes of Flores Island and last erupted in 2003. [less]

Seismic activity and volcanic have increased recently and the lava dome of Anak Ranakah is emitting a small plume of white steam.
Very little is known about Ranakah volcano. There is only one previous eruption, which constructed Anak Ranakah lava dome in December 1987 - January 1988 during the first historic eruption of 2247 m high Ranakah volcano. The lava dome produced powerful explosions with ash plumes up to 8 km height and pyroclastic flows. [less]
