Abstract: A significant number of rescue workers are killed or injured each year as they conduct searches within damaged or burning structures, unaware that the structure is unstable. The present invention provides a system and method for real-time detecting and monitoring structural instability that may lead to inevitable collapse of a structure. The system is capable of displaying data, including visual and/or audible signals, indicating structural instability. Additionally, the present invention is also directed to stability monitoring analysis processes for determining structural stability or instability.
