The disclosure relates to detecting seismic movements and providing at least one alarm notification based on the detected seismic movement. Particularly, a sensor device, which may be positioned in a subterranean part of a structure, may detect a seismic movement. The sensor device may make a determination as to whether the received seismic movement is greater than a predetermined threshold. If the seismic movement is greater than a predetermined threshold, the sensor device may transmit an alarm notification to one or more alarm devices, which may be located within the structure, indicating the seismic movement. The alarm device(s) may provide an alarm, notifying people in the structure of the seismic movement. This may provide an opportunity for the people to leave the structure before the seismic movement reaches the structure.
