Had a run in with a curb.

I hit a curb pretty hard the another night doing some fast turns. Everything on the car seems to be fine steering wise, (no major alignment problems, I turn corners now, I can hear this loud thumping noise. What could this be, im probally going to go under the car car and inspect the suspension, but I want to know a few things to look out for. Oh and its a 01 Civic LX
