“…The method is a corollary of the Least-Squares Collocation technique (LSC). The method was discussed in detail in El-Fiky et al (1997) and in El-Fiky and Kato (1999). In the present study, the outline of the method is explained and the results of its application to the present field of study are shown.…”

“…Thus, the problem is to extract the signals at any location from l by some filtering technique, considering that the noise (n) is limited to only the site or adjacent local regions, and tectonic signals may have rather wider spatial correlations in nature (El-Fiky and Kato, 1999). Variancecovariance analysis of data is a good measure to find such spatial correlation.…”

“…Such a function may be fitted by a simple mathematical function. Then we can reconstruct the signal at any arbitrary grid points (S) using this as such a fitted function, which is called the Empirical Covariance Function (ECF) (e.g., El-Fiky and Kato, 1999).…”

Global Positioning System (GPS) measurements were made to estimate the crustal deformation strain rate for the Deccan trap region, western India. Estimated horizontal velocity vectors in ITRF96 are in the range of 40-60 mm/yr with an average of 51 mm/yr in N47• E. Using the horizontal components of the velocity vectors, strain field has been estimated by the Least Square Prediction (LSP) method. An extension is observed along the west coast and south of Koyna and Warna reservoirs, transcending in to a region of compressive regime towards the interior of the shield area. The west coast geothermal province coincides with the extension regime. The collision between India and Eurasia is likely cause for compression regime. The results are discussed in conjunction with the seismo-tectonics of the study region.

“…The LSP method is a corollary of the Least-Squares Collocation technique. The application of the method to the crustal deformation data was discussed in detail in previous papers (El-Fiky et al, 1997;El-Fiky and Kato, 1999a). In this study, the total strain components were calculated following the method described by El-Fiky and Kato (1999a).…”

To estimate the elastic and inelastic strains in the Japanese Islands, we used horizontal velocity vectors at 917 sites of the nation-wide GPS network for the period April 1996 to March 1998. To segregate the signal and noise in the velocity vectors, we employed the Least-Squares Prediction technique (LSP). Estimated signals (displacement vectors) were differentiated in space to reconstruct the total strains (elastic plus inelastic). Then, we estimated inelastic strains of the islands using the inversion method introduced by Hori et al. (1999). The estimated rate of inelastic strains is of the order of 10 −3 μstrains/yr. Compared this with the rate of total strains of the order of 0.1 μstrains/yr, inelastic part was found to be negligible. Finally, shear stresses at the surface of the Japanese Islands have been estimated, based on the elasticity theory.

“…Applications to the estimation of the vertical movements were given by Hein and Kistermann (1981), Kanngieser (1983) and El-Fiky et al (1997). Papers on horizontal and vertical movements (El-Fiky and Kato, 1999;Wu et al, 2006;Kahle et all., 1995;Chatzinikos et al, 2013), were followed.…”
