no, not Katla, this one is a tad bigger
200 km x 25 km apparently

''Seismic activity has been ongoing in Bardarbunga in Vatnajökull for several weeks now. Bardarbunga is the largest volcano in Iceland, located in the country's largest glacier, Vatnajökull. This acitivity, scientists say, could suggest that the volcano is about to erupt or volcanos in that area.
Ever since Eyjafjallajökull erupted in April there have been speculations about the volcano Katla. After an eruption in Eyjafjallajökull Katla has usually followed. There are, however, no signs that Katla is about to erupt. Bardarbunga in Vatnajökull on the other hand, has been showing seismic activity for over five weeks. Ari Trausti Gudmundsson geologist says that over one hundred small earthquakes have been measured under Bardarbunga and the reason could be a possible magma intrusion deep under the volcano. Ari has given the Department of Civil Protection and Emergency Management his findings. Gudrun Johannesdottir a project manager with the department told Pressan.is that scientists are following the activity in Bardarbunga closely.
Omar Ragnarsson, a keen volcano enthusiast and former reporter, has also been following the activity closely and says in his blog on 12 March:
An eruption in the northeastern part of Vatnajökull could have greater ramifications than an eruption in Eyjafjallajökull since it could lead to catastrophic flooding.
The axle Bardarbunga-Grimsvötn is the center of the volcanic belt that runs from the southwest to the northwest of Iceland and the center of the mantle plume which is under Iceland. This mantle plume is one of the two largest in the world. The other one is under Hawaii.
The largest earthquakes recorded this year at Bardarbunga are 3,3 and 4,0 on the Richter scale, the largest recorded since 2002.
The volcano at Bardarbunga is estimated to be around 200 kilometers long and up to 25 kilometers wide. It is covered in ice. Bardarbunga has never erupted in historic times but the largest lava flow in the world stems from Bardarbunga when it erupted 8500 years ago.''

could we see a flood basalt eruption on Iceland?
