Test events are the 1994 Northridge ( M w = 6.7, California), the 1996 Copala ( M w = 7.3, Mexico), and the 1996 Pinotepa Nacional ( M w = 5.4, Mexico) earthquakes. In the case of inversions...

... are larger than those of the Copala, Guerrero, earthquake of 14 September 1995, which was a shallow (16 km) thrust fault with a similar magnitude ( M w = 7.4). The large PGA generated by the Chiapas earthquake are probably due to an enhancement of the signals produced by the up-ward intraslab propagation...

Indeed, the coastal areas in the epicentral zone were hit by a tsunami ( Ortiz et al. , 1996 ) that was unusually large for a Mexican subduction zone earthquake. Simultaneous inversion of permanent deformation data caused...

... ) ) , the cumulative acceleration shows the presence of outliers, corresponding to earthquakes M w > ∼ 7 . In some cases, outliers are due to earthquakes where the directivity of the seismic energy is radiated away from the recording seismic stations. For example, in the case of the 1995 Copala...

... in the forearc region. The estimate of Q ( f ) across the central mvb can be used to predict the spectrum of Lg waves at the northern end of the mvb from future coastal earthquakes. An example is provided by the Copala earthquake of 1995 ( M w 7.4). The location of the earthquake is shown...
