Failing some sort of extra-sensory-perception there's no way that one could know. Hearing/seeing or otherwise perceiving the tree (regardless of whether it is vertical, falling through the air or lying horizontally) is a prerequiste for knowledge in this case.
Moreover, if I encounter a tree lying horizontally, I may infer that it fell, but I cannot know for certain that it fell - all I can know (and not even for certain, since my senses do fail me from time to time) is that there is a tree lying horizontally. |

I wrote a paper last semester which answers this question: |

It sounds therefore it is? Why do you need to hear it to know that it fell? Are you blind? |

You don't unless you look but things happen all the time and we don't hear it or see it unless we are looking to. And then u still don't know when! |

Because unless you are deaf or it has been visited by a alien spiecies, a tree would produce sound waves when it fell, no matter how it happened to fall. |

How do you know if the tree fell, if nobody is around the tree? Not even you are not around the tree. |
