Sentence examples for main shock using from inspiring English sources

We first estimate the fault planes of the three foreshocks and the main shock using the distributions of the aftershocks ("Estimation of fault planes" section).

Finally, we conducted 3-D dynamic rupture simulations of the main shock using the initial stress distribution, which was the sum of the static stress changes caused by these foreshocks and the regional stress field.

We relocated the main shock hypocenter of the 2008 earthquake and the 1276 aftershocks that occurred within 1 week after the main shock using the seismic velocity structure modeled in this study.

Here we systematically analyze temporal changes of material properties and nonlinear site response in the shallow crust associated with the Tohoku main shock, using seismic data recorded by the Japanese Strong Motion Network KiK-Net.

Wu and Peng (2011) analyzed the KiK-Net data of the Tohoku main shock using the spectral ratio technique and found that the majority of resonance frequency drop is recovered within several hundreds of seconds after the Tohoku main shock, but they suggested that the recovery process was still going on at the end of the Tohoku main shock record.

Here we follow that study and systematically analyze long-term changes of material properties in the shallow crust from one year before to 5 months after the Tohoku main shock, using seismic data recorded by the Japanese Strong Motion Network KiK-Net.

Ozawa et al. (2011) estimated the afterslip distribution in and around the source region of the main-shock using GPS data.

Figure 5 shows the coefficient estimates, standard errors, and P values for all of the effects under the main-effect model and the interacting model for shock using the Brussels score values.

The static stress changes on the fault plane of the main shock were calculated using Okada (1992)'s solution.

To investigate whether the Tohoku earthquake has changed the susceptibility of near-surface material to further damages (e.g., Rubinstein and Beroza, 2004b), we check the slope between the resonance frequency drops and PGAs for all events before and after the main shock and use the slope as a proxy for damage susceptibility.

The spectral ratios during the immediate recovery process (i.e., within 300 s of the Tohoku main shock) are not used here as they are dominated by the strong nonlinear effects and immediate fast recovery associated with the Tohoku main shock (Wu and Peng, 2011).
