Mobil homes have some flexibility built into them so they can be transported on bumpy roads without snapping in half. This flexibility would help out in an earthquake. The biggest enemy of the mobil home is tornados/high winds. The second enemy is flooding. Mobil homes built in the last 10 years are a lot stronger than those built prior. When you see a mobil home on the news that looks like kindling, chances are that a tornado passed through; hence the nickname "tornado magnet". I would rather be in a mobil home during an earthquake than a concrete building, because if the mobil home roof collapses on you, you could probably stand up through the rubble and walk away.

I wouldn't loose any sleep if I were you... unless you live in Oklahoma.
