1 Unfortunately, foreshocks are just like any other small earthquake.

2 An increase in foreshock activity triggered the evacuation warning.

3 Signal earthquake is a foreshock in broad sense.

4 Signal earthquake is a kind of generalized foreshock.

5 The earth gave no indication with a foreshock or an electric signal or a water signal or anything else that an earthquake was about to begun.

6 The mechanisms of one foreshock and four aftershocks of Yushu earthquake were determined by the wavelet domain inversion method.

7 The TFCM can be used to judge foreshock series, aftershock series and normal seismic activities, and it can also be applied to describe the characteristics of regional seismic activities.

8 As others have concluded, the foreshock sequence (Fig. 7) was the most important evidence used in the imminent prediction of the Haicheng earthquake. ......

9 What is the probability that an earthquake a foreshock to a larger earthquake?

10 Signal shock and precursory earthquake swarm and foreshock activities always accompany the anomalous space-time patterns of seismic'ty.

11 The higher stress drops for the foreshock sequences show that the higher shear stresses have been stored in the area of main shock.

12 Even in areas where foreshocks are fairly common(), there is no way of distinguishing a foreshock from an independent earthquake.

13 Michael said it might help warn of a large impending earthquake by detecting foreshocks.

14 Sometimes there are more credible observations,[] such as reports of foreshocks.

15 In the Pacific Northwest, there is no evidence of foreshock activity for most historic earthquakes.

16 First motions and ratios of P to S amplitudes indicate that two different faulting mechanisms occurred during the foreshock sequence.

17 In this paper, a primary study was made on strong shocks with conjugate rupture by research for earthquake faults, deformation belts, foreshock and aftershock distributions in Chinese continent.

18 What is the probability that an earthquake is a foreshock to a larger earthquake?

19 We are expecting the appearance in the world of the second example of the successful impending prediction of a strong earthquake based on sequential foreshock activity.

20 Simultaneously, we also studied the subdimensional feature of 35 foreshock , aftershock and swarm series and found that 29 of the 35 had subdimensional texture.

21 At this time, we cannot tell whether or not an earthquake is a foreshock until something larger happens after it... so only in retrospect.
