Micro-tremors are very small amplitude vibrations in the ground and structures. Micro-tremors arise from natural effects such as ocean waves, geothermal reactions, small scale earthquakes in addition to cultural noise, defined as the mobility of people in the process of life. Micro-tremor’s records analysis uses different techniques. These techniques are spectral amplitudes from the reference point relative to the spectral rate or ratio of the vertical component of the spectral horizontal component. The soil is obtained information from dominant pulse periods that procures regarding to the work area by micro-tremor record surveillance.
