Cable sensor which is usually used for invaderinspection of sensitive places such as atomic power stations andother high security is considered to be available for rock noiseand impact detection, because the sensor can detect vibration atany point of a string, and can be used with extending more than ahundred meter or more. From a field test using cable sensor andmobile multimedia network, it was found that the impact sourcecaused by a steel ball dropping in the proximity of the sensingcable could be judged clearly from the order of rise time ofsignals of cable sensors, amplitudes of wave forms of signals anda topography pictured from peak values of signals transmitted byway of mobile mulumedia network. This newly developed systemis considered to be applicable not only to detect the resultantimpact of fallen rocks but also to monitor the noise produced bythe fracture of unstable rocks and sounds of falling rocks along a slope.
