Cracks shown here in the exterior and supporting structures of this home are indicative of subsidence damage associated with sinkhole activity.

More than 110 sinkholes formed in the Dover area of Florida during a freeze event in January 2010. Ground water levels dropped to record-setting lows as farmers pumped water to irrigate their plants for protection from the cold temperatures. The sinkholes destroyed homes, roads and sections of cultivated areas.
