The current speculation is that last night was only a prelude and not the main event.
Bardabunga is still active and the magma continues to push out into the dike.
But usually, the pattern has been that if it does something big, it will happen here in about an hour or two. Last night, the eruption started
sometime around 7 CST.

Many smaller eruptions happen there but go unnoticed because they happen beneath the glaciers. I believe this volcano erupted in 1793 and as the
result cause the mini-iceage in Europe for the next several years until the ashes fell out of the atmosphere.
Bardargunga is at north end of the Atlantic rift and runs the complete length of Iceland.
One thing that is certain, that the climate change people will be perplectic over this when the average temperature cools over the next few years.
