A magnitude 7.2 earthquake occurred on April 4,2010,in the upper Baja California peninsula of Mexico.The earthquake occurred in an area with dense GPS and borehole strainmeter observations stations.As GPS is capable of representing displacements occurring over a range of temporal and spatial scales,the displacements of several stations using the data before and after the earthquake are calculated,the results show that the stations close to epicenter is of great displacements which can up to 0.2m and most stations move towards southeast.Besides,the kinematic deformation series of several stations were obtained when a stable station was used as a reference station;it's shown that seismic waves can be derived from GPS observations,which is in very good agreement with borehole strainmeter observation.
