T his m a p com b ines two previously-relea sed ea rth fissure study a rea m a ps. T he Friendly Corners study a rea m a p (DM-EF-12) is now included in this relea se, DM-EF-3 version 2.0.

Introduction T his is one of a series of ea rth fissure m a ps prepa red b y the Arizona Geologica l Survey (AZGS) in a ccorda nce with Ariz. Rev. Sta t. § 27-152.01(3). AZGS collected loca tion inform a tion from previously conducted ea rth fissure studies, reviewed a va ila b le rem ote-sensing a eria l a nd sa tellite im a gery, a nd conducted surfa ce site investiga tions throughout the study a rea . A rea sona b le effort wa s m a de to identify a ll ea rth fissures in the study a rea . N onetheless, som e fissures m a y rem a in unm a pped a s a result of one or m ore of the following:

1) Existing fissures m a y ha ve b een m a sked b y construction or a gricultura l a ctivities.

2) Incipient fissures m a y la ck clea r surfa ce expression. 3) T he surfa ce expression of fissures cha nges consta ntly a s new ea rth fissures develop a nd old ea rth fissures fill in. A b la nk a rea on the m a p does not gua ra ntee ea rth fissures a re not present. However, b la nk a rea s within the study a rea b ounda ry ha ve b een investiga ted, a nd no surfa ce evidence of fissures wa s found a s of the da te of m a p pub lica tion. Determ ining the presence or a b sence of a fissure a t a ny specific site m a y require a dditiona l m a pping a nd/or geotechnica l a na lysis.
