Abstract: The present research is an approach of studying the sequences as time frequency to amplitude analysis of the recorded ground accelerated earthquake seismic wave which is being propagated from source to receivers. Sequence can be derived from the various analyses of wave properties and it is realistic to be considered that the properties of the recorded seismic wave is related with subsurface in which the wave propagates. Time frequency to amplitude analysis is a way of studying seismic wave properties. The analysis deals with both amplitude and frequency effects instantaneously. Synthetic earthquake ground accelerated waves have been produced with wide range of variation in amplitude and frequency. Time frequency to amplitude analyses have shown that it can mark better sequences of the wave than time frequency analysis which is also made in this research. The analysis is also applied to the real up down component of ground accelerated earthquake waves and it has well estimated the sequences. It is revealed from the analysis that the technique can be further used for characterization of the geology of the earth.
