Looks like heavy monsoon rains opened up a few earth fissures in the Queen Creek area last week, the East Valley Tribune reported yesterday.
We’ve talked about earth fissures here previously. They are big nasty crevices that open up when ground water is over pumped. The good thing is the Arizona Geological Survey is undertaking a mapping project and has maps available showing where areas are prone to earth fissures (there are complex geological factors that come into play, these things don’t just pop up randomly across Phoenix.)
It’s definitely something though that you want to educate yourself on and understand if you are looking in an area prone to fissures.
