06:00 Een nieuwe dag, dezelfde eruptie.
Over het algemeen weer minder aardbevingen rond de eruptieplek, de lavauitstroom gaat echter onverminderd door.
Omdat de instroom in de scheur groter is dan de uitstroom, blijft de druk hoog, en is er nog steeds een kans op een nieuwe eruptie van de spleet. Dat kan buiten de gletsjer, maar ook onder de gletsjer gebeuren.
De grotere aardbevingen in de caldera blijven aanhouden.
11:00 Er heeft zich een nieuwe spleet geopend, zo'n 500 meter lang, en 1.5 km van de gletsjer vandaan.
De toegang tot het gebied is weer beperkt.
Deze nieuwe fissure is tussen de oude en de gletsjer.twitter:laraomars twitterde op vrijdag 05-09-2014 om 11:25:07 BREAKING! new fissure #eruption near #dyngjujökull - ný gossprunga að opnast nær jökli @RUVfrettir http://t.co/Q0y2H60BdE reageer retweet

quote:A new rift closer to Dyngjujökull
At about 7:00 UTC this morning reports came in that new eruptive fissures had opened to the south of the on-going eruption.
At 8:30, a surveillance flight with scientists from the IMO and University of Iceland observed the following:
Two new eruptive fissures formed south of the previous eruption site in Holuhraun, in a graben, that had formed above the intrusion, about 2km away from Dyngjujökull.
The eruptive fire fountains from the new fissures are substantially smaller than in the older fissure. Steam and gas rises in a south eastern direction from the fissure.
The cauldron in Dyngjujökull seems to have grown deeper since the last observation.
No changes are visible in Bárðarbunga.
Substantial amounts of SO2 are still being released to the atmosphere in association with the eruption. Conductivity measurements show a slight increase in conductivity in Jökulsá á Fjöllum, indication more waterflow. Some tremor was detected on seismometers shortly after 3:00 UTC last night. It decreased at about 6:00 UTC this morning. Considerable activity is in the northern fissure (fissure 1) and the height of the steam cloud is about 15,000 feet.
There are no indications of the eruption in Holuhraun being in decline. The lava from fissure 1 continues to flow to the east north east and has grown in area since yesterday.
Seismicity in the area is similar to yesterday’s activity. About 170 earthquakes were detected since midnight. Two earthquakes of magnitudes 4,4 and 5,3 were detected in the Bárðarbunga caldera region at around midnight UTC.
GPS displacements have continues to decrease and are now within uncertainty limits.
Four scenarios are still likely:
The migration of magma could stop, resulting in a gradual reduction in seismic activity and no further eruptions.
The dike could reach the Earth’s surface at different locations outside the glacier. Lava flow and/or explosive activity cannot be excluded.
The intrusion reaches the surface and another eruption occurs where either the fissure is partly or entirely beneath Dyngjujökull. This would most likely produce a flood in Jökulsá á Fjöllum and perhaps explosive, ash-producing activity.
An eruption in Bárðarbunga. The eruption could cause an outburst flood and possibly an explosive, ash-producing activity. In the event of a subglacial eruption, it is most likely that flooding would affect Jökulsá á Fjöllum. However it is not possible to exclude the following flood paths: Skjálfandafljót, Kaldakvísl, Skaftá and Grímsvötn.
