Growing evidence from Ohio, Arkansas, Texas, Oklahoma and Colorado links fracking wastewater injection (disposal) to an increased frequency of earthquakes. In addition, the collapse of the Baldwin Hills dam in December of 1964, resulting in the death of 5 residents and the destruction of 200 homes, was shown to be caused by fluid injection causing shifts in the stability of the ground supporting the dam. Many injection wells such as those on Inglewood oil field are located directly on known faults, increasing the potential for triggering of earthquakes. Recent earthquakes with epicenters on the Inglewood oil field have raised questions about whether these too have been triggered by oil field operations. One CA Earthquake Authority official has stated that his agency is not in a position to compensate policy holders for losses due to manmade earthquakes.
