Information on the Alpine Fault, with detailed
maps showing the location of the fault at various
localities. Produced by the Department of Geology,
University of Otago.
In 1951 Harold Wellman scanned all the available
aerial photographs of the South Island and
identified active fault traces. All his
observations are listed in tables, and his map is
the first to show New Zealand active faults.
Published in the New Zealand Journal of Science
& Technology in 1953, it was one of the
first of such studies in the world (PDF, 1 MB).
