Katla seismic activity

A number of small tremors at the 1km depth near Katla's western lava plug in the past 24 hours. Usual caveats about tremors and eruptive behaviour apply. The old saying "A watched pot never boils." has a certain synergy.

Have cropped and annotated the original Katla vent system diagram to give an idea of what features exist under the glacial cap and the approximate location of the current activity.
