A second effusive fissure eruption started in an ice-free area north of Bardarbunga, early this morning. The eruption is located in the Holuhraun lava field, where a small fissure opened Friday morning. No volcanic ash has been detected but lava has been flowing and flying.
Lava Strokes up to 70 meters high
The effusive eruption in Holuhraun produced up to 70 meter (230 feet) high lava fountains, according to a volcanologist. The active fissure is 1500 - 1800 meter long, considerably larger than the fissure that opened Friday morning.
Seismic activity was detected in the Bardarbunga region this morning, but less intense than in recent days. Today, the weather conditions are very unfavorable north of Vatnajokull, with high wind and rain forecast for today. Here is a webcam near the eruption site, but due to fog and rain, visibility is sometimes very limited.
10 - 20 times bigger than last time
According to Ármann Höskuldsson, volcanologist at the University of Iceland´s Institute of Earth Sciences, who is at the site, the lava flow from the fissure is about 10-20 times more than Friday morning. The eruption is estimated to be 10 to 20 times bigger than the one Friday morning, and looks "robust" says Dr. Hoskuldsson. He says the highest lava fountains can be seen at the southern end of the fissure, but at the northern end, they are less powerful.
This effusive fissure eruption is the third one in the area since last weekend. On August 23, a small subglacial eruption occurred near the Bardarbunga caldera in Vatnajokull. The eruption was shortlived, and did not break through the glacier, but did create calderas that were spotted a few days later. Early last friday, a small fissure opened in the Holuhraun lava field, north of the Dyngjujokull outlet glacer. That eruption lasted for 3 - 4 hours.
The Civil Protection Agency has maintained its level of preparedness at "danger", and previous road closures and area restrictions are in effect.Vatnajö
