1. A method for detecting an occurrence of an external event based on data taken by a plurality of mobile devices, the method comprising:

  • determining, using the processor, that each of a first set of data and a second set of data corresponds to the occurrence of an instance of the external event based on at least one harmonic characteristic of the first and second sets of data, wherein the first set of data comprises vibration and audio data taken from a vibrational sensor and an audio sensor of a first mobile device and the second set of data comprises vibration and audio data taken from a vibrational sensor and an audio sensor of a second mobile device;

    determining that the first and second sets of data occurred simultaneously, and are both attributable to a single source;

    discarding the second set of data and retaining the first set of data;

    communicating information determined from the first and second sets of data to a network component in the wireless communications network, the communicated data including at least location and time information; and

    based at least on the occurrences of the instances of the external event, determining, using the processor, an action to perform.
