Claim Text:
1. A seismic alarm and warning system comprising: a. a 3-axis accelerometer; b. at least one microphone; c. at least one radio frequency module; d. an electric-to-acoustic transducer; and e. a controller operationally coupled with the 3-axis accelerometer, the at least one microphone, and the at least one radio frequency module, wherein the controller is configured to monitor signals from the 3-axis accelerometer to determine the presence of a seismic event, to enable the at least one microphone, and to monitor signals from the radio frequency module for emergency broadcastings, wherein enabling of the at least one microphone depends on the signals from the 3-axis accelerometer, wherein the microphone records surrounding acoustics and is enabled by the controller to pick up surrounding acoustics at a predetermined time interval and to reproduce the acoustics through the electric-to-acoustic transducer.
