An earthquake “swarm” has been rattling Oklahoma since 2009. Most of the shaking has been small, but the phenomenon has left many Oklahomans feeling uneasy.

More than 10,000 individual tornado shelters have been built in Oklahoma since 1999 with the help of a state rebate program that provides up to $2,000 toward the cost of installing safe rooms in homes or underground.

So it seems the state is doing a lot to make taking shelter simpler and more affordable.
