Abstract

Relatively recent recognition of the
importance of endogenous lava emplacement
mechanisms requires updating of groundwater
models for some volcanic terranes because voids
produced during lava inflation play a more significant
role in their hydrogeology than has generally
been recognised. Highly integrated, underground
drainage systems in some very young lava flows in
Iceland exemplify the potentially complex, fissured
and conduit aquifers which may exist. Similarities
between such aquifers and easily polluted, karstic
conduit aquifers suggest greater research and more
careful and protective management of some volcanic
aquifers are warranted. Interpretation of aquifer
structure can be impeded on very old lava flows by
superimposition of sediments and accumulation of
weathering residues but, if emplacement was by
endogenous processes, then relicts of similar void
systems may persist and pose similar hazards.
