Small errors in the depth of the overcoring samples lead to large parameter estimation errors.
δd min is shown for the oil graph and δC = 0.1 pF. Figure 10 shows that, given a capacitance measurement, an error in the liquid depth deduced can be found.
It was observed that both Tr n and C R are enhanced, owing to the crack interfacial waves, which may lead to substantial errors in predicting the depth of a surface-breaking crack in actual concrete structures.
Therefore, attention should be paid to minimize the errors in positioning the depth of the samples.
However, event depth is the most difficult parameter to be resolved when there are no nearby stations, and the error in relative depth is about 5 km for the station distribution in this area.
The errors in the focal depths are estimated to be less than 2.5 km for events whose focal depths are freely determined (Nettles et al., 2011).
In order to predict future earthquakes, we analyzed earthquakes that occurred in each seismic active period (indicated by the hatched regions in Fig. 9), because the errors in the focal depths of old 7.0 ≤ M < 7.3 earthquakes lead to the degradation of data fitting.
A realizability condition for the variance of the topography error in the limit of zero bottom depth is proposed which is interpreted as a bound on the fractional error of the topography.
The Table 1 also includes the targets numbered as 4, 5 and 6 considered in Fig. 8b, showing the error in depth as −0.38 and −0.785 cm lateral error.
