Earthquake insurance policies have their own deductible that is separate from your home insurance deductible. Homeowners comparing earthquake insurance quotes will need to focus not just on the annual premium but also on deductible amounts. Deductibles typically run 10% to 20% of the coverage limit. If you insure your structure for $200,000 and have a 15% deductible, your out-of-pocket expense would be $30,000. If you have bought coverage for the contents of the home or additional living expenses while it's undergoing repairs, you may owe deductibles on those, too. Earthquakes more than 72 hours apart are usually considered separate events. That would mean a second claim and deductible. The deductibles, large as they may be, are considered uninsured losses for disaster relief. You may be eligible for low-cost loans to cover them.
