This paper discusses and presents the cumulative absolute velocity( CAV) parameters of the Wenchuan earthquake.Additionally,the CAV calculated from recorded data for the earthquake is compared to the peak ground acceleration( PGA),based on a brief analysis of background information.Accordingly,the paper studied the relationship between the CAV and PGA,and 3 CAV /PGA ratio charts were obtained in three different sub-directions.Linear and polynomial fitting operations were then used to analyze the potential discipline and characteristics in these directions.Finally,in the study,we investigated the applicability of using the CAV parameter for earthquake observation systems,and the CAV parameter was paired with the currently used PGA to provide earthquake observers and emergency responders with a theoretical basis.
