1. A system for detecting collapse of structures comprising:

  • a device for detecting vibration responses on exterior of said structure said device constructed so as to determine transient amplitude and decay characteristics of said structure said transient amplitude and decay characteristics indicative of collapse of said structure in real time;

    said device including at least one accelerometer, said accelerometer constructed so as to receive acceleration responses from a structure in real time and in at least one axial direction;

    said device including a filter and amplifier, said filter and amplifier constructed so as to connect to said accelerometer, said filter and amplifier further constructed so as to receive said real time acceleration responses, remove extraneous noise from said acceleration responses and amplify said acceleration responses;

    said device including at least one transmitter, said transmitter constructed so as to connect to said filter and amplifier, said transmitter further constructed so as to receive said filtered and amplified real time acceleration responses, said transmitter further constructed so as to convert said real time acceleration responses to an analog signal and transmit said signal; and

    said device including a first power source connected to said accelerometer, said filter and amplifier and said transmitter, said first power source constructed so as supply power to said accelerometer, said filter and amplifier and said transmitter, said first power source further constructed so as to obtain power from dependent and independent power supplies.
