Should I get earthquake insurance?

Kansas is not well known for earthquakes, but over the last couple of years we’ve had our share because of fracking going on in Oklahoma.
Today’s was the hardest at 4.8. I felt the whole house torque. Cracks have been developing in the walls and today’s quake made them worse.
So what can I do? I know I can’t file insurance on a pre-existing problem, but what about for future quakes?
