Description:
This is one of a series of earth fissure maps prepared by the Arizona
Geological Survey (“AZGS”) in accordance with Ariz. Rev. Stat. §
27-152.01(3). AZGS collected location information from previously
conducted earth fissure studies, reviewed available remote-sensing
aerial and satellite imagery, and conducted surface site
investigations throughout the study area. A reasonable effort was
made to identify all earth fissures in the study area. Nonetheless,
some fissures may remain unmapped as a result of one or more of
the following:
1) existing fissures may have been masked by construction or
agricultural activities;
2) incipient fissures may lack clear surface expression;
3) the surface expression of fissures changes constantly as new
earth fissures develop and old earth fissures fill in.
A blank area on the map does not guarantee earth fissures are not
present. However, blank areas within the study area boundary
have been investigated, and no surface evidence of fissures was
found as of the date of map publication. Determining the presence
or absence of a fissure at any specific site may require additional
mapping and/or geotechnical analysis
