ACKNOWLEDGEMENTS
This work was done in part at Imperial College,
London. I would like to thank Dr. Neville J. Price of
Imperial College for fruitful discussion and interest in
this study. Mr. Eysteinn Tryggvason, Nordic Vol-
canological Institute, introduced me to the Vogar
fissure swarm, from which the present study has
developed. Discussion and information from Mr. Jón
Jónsson, National Energy Authority, and Dr. Páll
Einarsson, Science Institute, University of lceland,
has been very useful for me. Dr. Price and Dr. Ein-
arsson read a preliminary draft of this paper and
suggested many improvements.
