Methods and systems are provided for detecting the occurrence of events utilizing data taken from multiple mobile devices in a wireless communications network. At least a first set and a second set of data is received at the network from a first and second mobile device. The first and second sets of data corresponding to vibration and audio data taken from the mobile devices is analyzed to determine that each set of data corresponds to the occurrence of an instance of an event. An action to perform is then determined based on the occurrences of the instances of the event.
