Tree damage liability

Just at my house we lost 5 trees. We live in East Moriches. My uncle in Bellport lost 4. They are down everywhere. Through houses, on cars and boats, and on top of fences. So who is responsible if a tree falls from my yard onto my neighbors? The answer is that I have no liability for damage if the tree was sound (in good condition), but if the tree was decayed and unsound I will probably be liable. Here is to hoping the tree was sound.
