From all the reports I've read about the event, it appears that a dike has some magmatic material moving through it, sending shudders to the seismographs. Nothing to be alarmed about at the moment, but everyone and their aunts all believe that it's only a matter of time before Katla erupts.

Begin forwarded message:
Small seismic swarms have occurred near Katla volcano (S Iceland), Henggil volcano (SW Iceland) and a weaker swarm near Askja (N-Central Iceland) during the past 48 hours. The cause of the swarms is unclear and their intensity is not alarming. They are not necessarily volcanic, but could related to tectonic stress release around the main Icelandic rift zones.
