Lava analysis from the Friday eruption at the University of Iceland showed that the erupted basalt magma is relatively rich in magnesium (>7 wt% MgO) which suggests that it likely originates from a deeper source, directly connected to the upper mantle, rather than from an existing shallow magma reservoir under Bardarbunga (or Askja) volcano.
In the meanwhile, it is now believed that the 23 Aug event in fact was another (probably the first) eruptive episode, but went unnoticed at the surface because it failed to break through the glacier.
