Collapse sinkhole in a salt dome in Daisetta, Texas (September 2008). Salt is particularly susceptible to rapid dissolution causing large bowl-shaped sinkholes. Injection of fluids into this salt dome increased the dissolution of the salt causing a 60-foot deep sinkhole that covered several acres and destroyed many buildings.

Cover-collapse sinkhole in limestone near Frederick, Maryland (September 2003). Many sinkholes occur along highways where rainwater runoff is concentrated into storm drains and ditches increasing the rate of sinkhole development (note the sewer drain pipe beneath roadway).

The images reveal significant erosion of the island, likely due to inundation by waves and surge.This erosion resulted in the disappearance of an oil-protection berm constructed follow the BP oil spill. Due to this island's cumulative damage from previous storms like Hurricane Katrina, it remains in question whether this beach system will ever be able to fully

Photos from Dauphin Island indicate beach erosion and island overwash, furthering the erosion the island has seen during repeated storm events -- Ivan, Katrina, Gustav and Isaac -- that have led to the island's increased vulnerability to future storms.
