Has this been posted before, happened on the 29th August, Mount Tavurvur  Papua New Guinea    Amazing.

I was expecting a bigger eruption but not that soon! Spectacular eruption happened just an hour ago! You can see the shockwaves and lava bombs on the side of the volcano!     Karyo

The Icelandic Road Administration has closed some highland roads close to Herðubreið and Askja and has issued a map that shows which roads are closed in light of a possible eruption in Bárðarbunga volcano, Northeast Iceland.

Seismic activity in the area continues. Since midnight yesterday the Iceland Met Office has registered more than 800 earthquakes, the biggest about 4.5 in magnitude, visir.is reports. 

The river Jökulsá á Fjöllum might flood on a scale that could change the shape of the mighty Dettifoss waterfall and wipe out the roads and bridges in its path, visir.is reports. The famous natural wonders Ãsbyrgi and Hljóðaklettar were formed in a previous flood of an immense magnitude.

Should an eruption occur, the flood would take about ten hours after an eruption starts to reach the sea.

The intense seismic activity that started on 16 of August at Bárðarbunga persists. Very strong indications of ongoing magma movement, in connection with dyke intrusion, is corroborated by GPS measurements. There are currently two swarms: one to the E of Bárðarbunga caldera and one at the edge of Dyngjujökull just E of Kistufell. At 2.37 am on the 18th a strong earthquake (M4) was located in the Kistufell swarm.

This is the strongest earthquake measured in the region since 1996. As evidence of magma movement shallower than 10 km implies increased potential of a volcanic eruption, the Bárðarbunga aviation color code has been changed to orange. Presently there are no signs of eruption, but it cannot be excluded that the current activity will result in an explosive subglacial eruption, leading to an outburst flood (jökulhlaup) and ash emission. The situation is monitored closely.

Kverkfjöll volcano

either i am imagining it or it looks like icemelt is happening there

 

soon see what it looks like tomorrow

Certainly does. Could be just increased thermal activity due to a change in the underlying plumbing.

Volcanic activity worldwide 19 Aug 2014: Bárdarbunga volcano, Sakurajima, Stromboli, Reventador, Tungurahua

Stromboli (Eolian Islands, Italy): Lava flow activity continues. However, the recent surge in lava effusion seems to have considerably lost strength compared to yesterday.##

Bárdarbunga (Iceland): Intense earthquake activity continues, but there is no signs of magma reaching the surface, i.e. a new eruption of the volcano yet.

So far, 164 quakes of magnitudes 1.2-2.8 have been detected today and tremor remains elevated.

The quakes cluster in an area at the NE part of the volcanic system. This is where a new intrusion is likely occurring at the moment, but it is uncertain if it will result in an eruption.

A new webcam has been installed at approximately 30 kilometers (20 miles) from the likely location an eruption is expected to start. (from earlier)

Sakurajima (Kyushu, Japan): Since about a week ago, the frequency of explosions from the volcano has drastically increased and is now again almost similar to its intense phases of last year.

On 13 August alone, a record number of 9 explosions were registered. Ash plumes have been rising to 5-10,000 ft (1.5-3 km) altitude.#####

Reventador (Ecuador): Mild activity consisting of occasional small explosions, characterized as "moderate" by IGEPN, continues at the volcano. Most of the time, the volcano is hidden in clouds and this activity is inferred from seismic signals.###

Tungurahua (Ecuador): The volcano's activity remains moderate with frequent small to medium sized strombolian- to vulcanian-type explosions.

This ongoing type of activity suggests that the volcano in a phase of having a relatively open conduit allowing magma to rise to the crater with no major obstacles. Incandescent ejecta are visible at night.#####

Some stronger explosions cause shock waves that let windows and roofs of houses in nearby areas vibrate. Ash fall has occurred many areas around the volcano including the sectors of Píllate, Bilbao, Mocha, Quero and Tisaleo.##########

are they pools outside the crater and the venting of gas and steam normal for that volcano or is that to do with the current activity?

hi buried

the steam and gas are normal

 

there was mainly ice cover yesterday when i looked yesterday

 

lets see what this shows tomorrow now

still lively but the quakes do look smaller

 

however that can change vey quick

Alert: Area North of Bárðarbunga Volcano Evacuated By Benedikt Jóhannesson August 19, 2014 21:41 Updated: August 19, 2014 22:09

Posted Image

The Police Commissioners in Húsavík and Seyðisfjörðyour have decided  to close and evacuate the area north of Vatnajökull following the seismic activity in Bárðarbunga.

This decision is a safety measure. It cannot be ruled out that the seismic activity in Bárðarbunga will lead to a volcanic eruption. There is no change in the seismic activity at the moment and no sign of an eruption but experience shows that seismic activity can be ongoing for a long time without an eruption. This is first and foremost a precautionary measure since the evacuation of the area is impossible at short notice.

In accordance with procedure, the National Commissioner of the Icelandic Police has raised the Civil Protection level to Alert Phase. All roads leading into the area are now closed and the authorities in Húsavík and Seyðisfjörðyour are evacuating the area north of Vatnajökull. 

The Civil Protection Alert Phase reads as follows: “If threat assessment shows that hazard is increasing, a preventive measure must be taken immediately to secure the safety of those who are in the area. That is done by strengthening response measures in the area, and by taking preventive actions such as evacuation and closing off the area in question. Preparedness and warnings are also common in this phase."

from the looks of the recent earthquakes its looking more and more like if anything is going to happen its going to be a fissure eruption with the quakes taking a clear line and also the quakes at both sites tending to rise and fall together it would lead you to think there is a clear connection between the two. don't quite know what the first swarm to the northwest of the now main swarm was maybe the intrusion of lava started progressing then found a weaker and easier passage or maybe it was where the ground fist started to slip and give way.

 

its going to be really interesting to see what happens in the coming days hopefully if something happens its explosive so we don't really need to care apart from planes but if we happen to get a fissure eruption it could be quite a scary time we would need to track closely what gases were coming out.

 

theres still every chance it will just die off and nothing will happen though but that's some amount of quakes for nothing to come at the end of it only thing is though quake sizes haven't been that high but that could change closer to a main event.

Yeah, earthquake activity seems to have really shot up in the last hour or so. Probably just normal variances in the earthquake magnitudes, as we have seen this is recent days, only for it to quieten down again.

Last night the National Crisis CoordinationCentre was fully activated after a decision was taken to evacuate the highlands north of Dyngjujökull (part of Vatnajökull glacier). The area is now closed and has been evacuated. These actions were taken following seismic activity around the Bardarbunga caldera in the last few days. The area that has now been closed is both large in size and unpopulated  There are still no signs of eruption but these security measures have been taken since it would not be possible to evacuate the area in time should a sub-glacial outburst flood occur from Vatnajökull as a result of an eruption.
At 03.00 the area had been evacuated. A map of the closed area is available at the website of the Icelandic Road and Coastal Administration: http://www.vegagerdin.is/media/umferd-og-faerd/Halendi.pdf In the northwestern part of Vatnajökull glacier the seismic activity is stable, with the main area being northeast of Bardarbunga. Over 300 earthquakes have been detected since midnight. The strongest event was of the magnitude 3.0. Another event happened inside the Bardarbunga caldera and was of the magnitude 2.7. 
Today The Coast guard airplane, TF SIF, will make a surveillance flight over the area with scientists and representatives of the Civil Protection, if weather conditions allow. Police and ISAR units will enforce the closure of the area. The situation will continue to be closely monitored.

The current situation at Bárðarbunga is many times more powerful than the one that led to the Gjálpar eruption in 1996. Several hundred earthquakes were detected back then, but today they're already in the thousands. Scientists interpret this as a massive magma movement that may quickly surge towards the surface.Kristín Vogfjörð, research director at the Icelandic Meteorological Office, says that the current seismic activity at Bárðarbunga is many times more powerful than any on record for the site."It's very powerful," she says. For comparison she notes that thousands of quakes have been measured at Bárðarbunga in the past week, but in the Gjálpar eruption in 1996 they were only a few hundred.The activity is interpreted as magma moving up under the Bárðarbunga caldera, then moving into an underground chamber to the northeast, under the Dyngjujökull glacier. It's possible that the magma stops there and never reaches the surface."That's a possibility - if the chamber can hold all the magma," says Kristín. She says that GPS readings suggest that the pressure is stable while the magma moves away from Bárðarbunga into this chamber."While this is going on, it may never reach the surface. But we still need to keep an eye on it because the volume of magma is incredible," she adds.There are still no signs that the magma is heading for the surface. Kristín says that it's still at a depth of 5-10 kilometers."There is no indication that it's moving further up than that. But if it were to happen, it would happen very quickly," Kristín states.

70 quakes at M2 or stronger between 10:15 this morning and 16:15 this afternoon. 

 

215 quakes at M2 or stronger in the last 48 hours.

 

So over 25% of quakes in the last 48 hours have occurred in the last 6 hours (12.5% of the time period).

 

So as John said earlier it is ramping up

I suppose the 2 questions have to be

 

1) Do we have any seismic data relating to the size of that chamber?

 

2) What Volumes are we talking about the the comment above says the volume is "incredible"
