Sentence examples for main shock which from inspiring English sources

In the case of the Tohoku earthquake, the Miyagi quiescence started 23.4 years before the main shock, which is consistent with previous giant earthquakes.

Therefore, we remove all earthquakes included in Obs 8) except for the main shock, which is a declustering process based on the χ2-test.

The hypocenter distance is used for aftershocks, and the rupture distance (shortest distance between the station and rupture surface) is used for the main shock, which is calculated according to the fault slip model provided by the USGS.

Beneath Mt. Kurikoma, aftershock distribution delineates one of the unfavorably oriented fault planes of the main shock, which implies that the low-velocity zone around the fault plane is related to the presence of overpressurized fluid.

With the seismological knowledge, the similar slip amounts presumably imply that the stress drop for the largest aftershock is higher than that for the main shock, which means that there was a strong localized asperity.

Recent observations of stress states on other faults after large earthquakes fall into two viewpoints: one is that stress states are little affected by the main shock, which suggests that the stress drop of the main shock, relative to the tectonic stress level, is small (e.g. Kubo and Fukuyama, 2004).

In the present case, in addition, some aftershocks beneath the outer rise were induced by the east-west extension field made by the main-shock which released the compressional stress caused by the subduction of the Pacific plate.

We then invert the obtained displacement fields associated with the foreshock on March 9, the mainshock on March 11, the two M > 7.0 aftershocks, and the possible transient deformation between the foreshock and the main-shock, which we term 'the transient' for simplicity.

Dotted contour lines show the strength distribution of the radiation energy (greater than 50% of the maximum value) for the main shock occurrence which was obtained by Honda et al. (2011) using the back-projection approach.

The remaining events constitute our "main shocks", on which we are going to apply the GPD and the GEV methods described above.

We conducted observations continuously from April 15 , 2016 to May 19, 2016 (Table 1), and obtained seismic data from the main shock (Mj 7.3), which occurred on April 16, 2016, at stations KR02 and KR04.
