Please help!! My fish tank leaked onto my hardwood floors!?

My tank sprung a leak in the middle of the night. I came down stairs the next morning and about 25 gallons was missing from my fish tank. All the water leaked down under the floor. I have hard wood floors and a crawl space under that. What should I do? I have already soaked up as much as I could and have set up fans on it. Any other suggestions. Will my floor be ruined?
