Abstract

On the Leitin shield volcano in SW Iceland the area distribution of tumuli is mainly controled by the plan curvature. A density increase in tumuli is associated with peaks in the plan convexity. This follows because high plan convexity forces the distributary tube system which supplies magma to the tumuli to branch vigorously. Large lava-inflation structures such as lava rises occur in areas where there were restrictions to branching
