Commissioner John Doak says quake damage can cripple the finances of property owners who haven't purchased policies.

A report released last week from the U.S. and Oklahoma Geological surveys suggests an earthquake “swarm” continues to affect central Oklahoma after a record 5.6-magnitude quake rattled Oklahoma in November 2011.

Since January 2009, more than 200 magnitude 3.0 or greater earthquakes have hit central Oklahoma — marking a significant rise in the frequency of the seismic events, the survey reported.
