Device operates
It follows that the operation that Fig. 4 will be used to describe earthquake intensity estimation unit 10 according to an embodiment of the invention.Figure
4 is the flow chart illustrating the operation of earthquake intensity estimation unit according to an embodiment of the invention.In the following description, will be regarding feelings
With reference to Fig. 1 and 2 depending on condition.In the present embodiment, earthquake intensity estimation side is implemented by operation earthquake intensity estimation unit 10
Method.Therefore, the earthquake intensity according to the present embodiment is replaced to estimate with the following description of the operation of earthquake intensity estimation unit 10
The description of method.
Receive seismic data and the step of source position information
As shown in Figure 4, initially, in earthquake intensity estimation unit 10, from seismic detector 20 one of communication unit 16
Receive seismic data, and receive source position information (step A1) from seismism observation system 40 further.Communication unit
Received source position information is also exported focus and determines unit 12 by unit 16, and by received seismic data
Output is to adjacent area designating unit 12.Note, if communication unit 16 not yet receives source position information and earthquake wave number
According to, then communication unit 16 enters resting state.
Determine the step of hypocentral location
Occur it follows that focus determines that unit 11 determines based on the source position information received in step A1
Whether the position of the focus 23 of earthquake is in setting district 30 (step A2).If the result of the determination in step A2 is focus 23
Position not in setting district 30, then the process in earthquake intensity estimation unit 10 terminates.On the other hand, if in step A2
The result determined be the position of focus 23 be in setting district 30, then focus determines that unit 11 notifies adjacent area designating unit 12
To perform step A3.
Adjacent area given step
It follows that when determining that unit 11 receives notice from focus, adjacent area designating unit 12 is specified with the most defeated
Go out the adjacent area (step A3) that region that the seismic detector 20 of seismic data is installed in is adjacent.Such as, in fig. 2, as
First the seismic detector 20 that fruit is installed in region a exports seismic data, then adjacent area designating unit 12 specifies region B conduct
Adjacent area.
Determine the step of decay
It follows that decay determine unit 13 via communication unit 16 from the adjacent area being arranged on specified by step A2
Seismic detector 20 obtains seismic data.Decay determines that unit 13 is then based on pre-conditioned determining whether by accessed
Amplitude specified by seismic data is decayed (step A4).
Now step A4 is described by use Fig. 5 A and 5B.Fig. 5 A is to be shown in which to determine not yet in step A3
The figure of the exemplarily seismic wave in the case of decaying, and Fig. 5 B is to be shown in which to determine in step A3 to decline
The figure of the exemplarily seismic wave in the case of subtracting.
In step A4, such as, if the amplitude of S ripple such as after the generation of earthquake 30 seconds or later default time
Between point (hereinafter referred to as " determining time point ") place or afterwards more than or equal to threshold value, then decay determines that unit 13 determines still
Decay, as shown in Figure 5 A.On the other hand, as shown in Figure 5 B, if the amplitude of S ripple is determining at time point or it
Afterwards less than threshold value, then decay determines unit 13 to determine to decay.Note, although threshold value is set in Fig. 5 A and 5B
The 80% of big amplitude, but the present embodiment is not limited to this.Threshold value can be based not only on the percentage ratio of peak swing and be set, and
And can be set by absolute value based on amplitude, or can the group of absolute value of percentage ratio based on peak swing and amplitude
Incompatible it is set.
Decay determines that the time can also be used as the most to have occurred the coefficient of carried out determination for decay by unit 13.?
In this case, if the amplitude of seismic wave sets the time period more than or equal to threshold value down to continuing one, then decay determines unit
13 determine that decay not yet occurs.
In the present embodiment, multiple seismic detector 20 is installed in each area, as described above.But,
If the number of seismic detector 20 is too big, then the processing speed of earthquake intensity estimation unit 20 will be likely to reduced.For this reason,
In step A4, after getting seismic data from the seismic detector 20 being arranged in adjacent area, decay determines unit 13
It is obtained in that by the meansigma methods of the amplitude specified by accessed seismic data.In this case, decay determines unit
13 can use obtained meansigma methods to determine whether decays.
If the result of the determination in step A4 is to decay to occur, then the knot of the process in earthquake intensity estimation unit 10
Bundle.On the other hand, if the result of the determination in step A4 is to decay not yet to occur, then Fault Rupture site setting unit 14 is held
Row step A5.
Set the step in Fault Rupture place
In step A5, Fault Rupture site setting unit 14 position based on the adjacent area specified in step A2,
In setting district 30, set the Fault Rupture place 24(estimating to occur Fault Rupture see Fig. 2).In the present embodiment, setting district 30
Be set at the border 22 along continental plate band-shaped in.Therefore, in step A5, such as, Fault Rupture site setting list
Fig. 2 sees at the border 22(of continental plate in unit 14) above specify the place closest to adjacent area, and by this site setting
For Fault Rupture place 24.
Calculate the step estimating earthquake intensity
It follows that estimate that earthquake intensity computing unit 15 comes centered by the Fault Rupture place 24 set in step A5
Calculate and estimate earthquake intensity (step A6).Figure is seen with the focus 23(of earthquake if not yet calculated before the execution of step A6
2) the estimation earthquake intensity centered by, then estimate that earthquake intensity computing unit 15 can also be with the focus 23 of earthquake in step A6
Estimation earthquake intensity is calculated centered by (see figure 2).
In the present embodiment, it is used for calculating and estimates that the method for earthquake intensity includes non-patent file 1 above-mentioned
Disclosed in computational methods, and such as, estimate that earthquake intensity computing unit 15 uses table below to reach formula 1 to 4 and calculates and estimate
Meter earthquake intensity I.
In following expression formula 1, PGV600It is with reference to the maximal rate [m/ under basis (the S wave velocity of 600m/s)
S], Mw is instantaneous earthquake magnitude, and D is the degree of depth (if the degree of depth of focus is 10kM or the least ,=0) of focus.At following table
Reach in formula 1, the distance between the place that x is focus 23 or Fault Rupture place 24 and seismic detector 20 is installed in.Note, make
For seismic detector 20 in this case, to depend on the circumstances and select optimal seismic detector 20, such as be positioned in the zone
Seismic detector at the heart or the seismic detector on the border 22 closest to continental plate.
In following expression formula 2, Mjma is " Japan Meteorological Agency earthquake magnitude " (the non-patent file 1 see mentioned above).
Additionally, in expression formula 3 and 4, PGV is the maximal rate [m/s] on the ground surface at each place.In expression formula 3,
ARVi is the speed amplification coefficient on the ground surface at each place.
[expression formula 1]
log(PCV600)=0.58Mw+0.0038D-1.29-log(Rm+0.0028*100.50M)=0.002x
[expression formula 2]
Mw=Mjma-0.171
[expression formula 3]
PGV=ARVi×0.90×PGV600
[expression formula 4]
I=2.68+1.721og(PGV)±0.21
The step of output estimation earthquake intensity
It follows that estimate that the estimation earthquake intensity calculated is exported seismism observation by earthquake intensity computing unit 15
System 40(step A7).Therefore, the estimation earthquake intensity calculated is published to each place by seismism observation system 40.
If there is Fault Rupture, then bigger region is calculated described estimation earthquake intensity, and therefore, seismism is observed
System 40 can issue the estimation earthquake intensity of larger area.
After step A7 is performed, step A3 is executed once again.In step A3 in this case, adjacent area refers to
Cell 12 specifies new adjacent area based on specified adjacent area.Such as, if region B has been designated as adjacent region
Territory, then specify the region C adjacent with region B.
Thereafter, step A4 is performed, and decay determines that unit 13 determines whether in the adjacent area reassigned
Seismic wave is decayed.If decay occurs, then step A5, A6 and A7 are further executed.
In other words, in the present embodiment, step A3 to A7 is repeatedly performed until determining in step A4 and having occurred
Till decay.For this reason, from the beginning of the region that seismic wave is detected first, in respective regions one by one
Ground, it is determined whether decay in seismic wave.Therefore, according to the present embodiment, extensive disconnected even for being attended by generation
The earthquake that layer ruptures, it is also possible to suitably estimate earthquake intensity.
