Oct. 1998 - "Tatlow said the Department of Water Resources will begin a subsidence monitoring program in the Phoenix area by the end of the year. ... the aquifer below will never be able to hold as much water as it used to, because the sediments have been permanently compacted.... Sun City is dropping 2.8 centimeters per year, and the area around Luke Air Force Base is subsiding 2 to 3 centimeters a year."
2.54 centimeters equal one inch.

What hidden dangers lurk under land you're buying?

Oct. 8, 2005

Regarding "Fissures generating anxiety" (Republic, Oct. 1):

While a map from 1996 may be out of date concerning locations of earth fissures and land subsidence in the southeast Valley, this issue should be of no surprise.

Geologists from the U.S. Geological Survey (including my father) have consistently studied, written reports and produced maps of this area documenting the existence of fissures and subsidence since the 1960s. Local, county and state officials are aware of this issue.

As a teenager in the mid-1970s, I can remember going out in the field with my dad to see a fissure near the San Tans. Even back then, it had been filled in with rubble and debris by a bulldozer, as if to conceal it.

Officials need to do more to help inform future homeowners just what might be hiding under the land they may be buying. - Jan Laney, Phoenix
