Description:
Land subsidence and earth fissuring
have occurred in large portions of south
ern Arizona, where they have caused a
variety of structural damage and landmanagement
problems. As Arizona’s
population continues to increase, so wifi
the demand for ground water. Subsi
dence and earth fissuring wifi continue,
extend into new areas, and create addi
tional problems. The purpose of this
report is to describe, in terms that are
understandable to persons who are not
trained in geology, what land subsidence
and earth fissures are, why they develop,
where they occur, what kinds of prob
lems they create, and what can be done
about them.
Dedicated to the memory of Cathy Schulten Wellendorf (1956-1988).
