Bardarbunga (Iceland): The eruptive activity at Holuhraun has not decreased, the Icelandic Met Ofccie writes: “Magma flow is between 100 and 200 m3/s. The lava advances by about 1 km/day and its area yesterday afternoon was around 16 km2.
The eruption sites are the same as before. The eruptive intensity on the southern fissure that opened on Friday is much less than on the northern fissure that has been active since the beginning of the eruption.
The lava tongue now extends 11 km to the north and has reached the western main branch of Jökulsá á Fjöllum river. However, no explosive activity due to the lava and river water interaction has been observed, but steam rises from the lava. A white eruption cloud rises 3 – 4 km and is directed to the north and northeast.
The eruption continues at similar levels as during the previous days. At the eruptive fissures, most lava emission in the form of lava fountains is now concentrated from the central vent on the main fissure.
Lava flows are expected to reach the Jokulsa a Fjollum glacial river in the course of today. This could lead to phratomagmatic explosive activity. Access to the area is strictly restricted and Iceland police has arrested several people who entered the area on their own, according to RUV.
Kilauea (Hawai’i): (6 Sep) Lava flows continue to advance downhill through the jungle on a path that will miss Kaohe Homesteads, having first entered and overtopped several large ground cracks on Kilauea volcano’s east rift zone. The farthest lava front is now 13.3 km (8.3 miles) from the vent and 1.2 km (0.7 miles) from the east boundary of the Wao Kele o Puna Forest Reserve, and moving northeast parallel to the boundary.
The latest map issued shows 3 large flows moving away from the cracks, whose path will take them downhill parallel to the Forest Reserve boundary and the threatened community of Kaohe Homesteads. Issued maps for the first time have blue lines indicating probably flow direction based on topography, showing that without any major changes the current flow will advance around Kaohe and if it continues long enough, cross the highway just north of Pahoa.
The question still remains whether these spill-overs can take the whole volume of lava erupted by the volcano, or whether lava finds its way into other large cracks which can funnel it closer to the inhabited zone. After that, the major question is how long the pipeline feeding the flow can remain stable. Will it be just one more month like the Kahaualea 1 flow ending in April 2013, or a full year like the Kahaualea 2 flow which ended in June 2014? For now, the closest communities are still safe but the highway appears under threat and there are other communities beyond.
Within the last 24 hours, the Volcano Observatory has upgraded Kilauea’s status from a watch to a warning, Civil Defense has closed the threatened neighborhood to non-residents, the Mayor has declared a state of emergency, and most recently the Governor has issued an emergency proclamation, setting the stage for possible evacuations and construction of an alternate route into the district should the highway be cut off by lava. The warnings indicate that authorities believe lava may enter the community within 5 to 7 days, but that will be a conservative guess and for now the lava flow continues to flow parallel, but away from the community through undeveloped land.
Colima (Western Mexico): Although not making headlines, the volcano has remained quite active during the past months. The attached photo by Tapiro (@tapirofoto / twitter, taken yesterday morning, shows intense degassing at the volcano with possibly some ash in the plume.
