The invention monitors the earthquake wave generated by the natural earthquake, identifies the earthquake wave generated by the natural earthquake and quantitatively determines the strength of the natural earthquake by using the quiet period between the continuous natural earthquakes in the natural earthquake frequent period; the natural earthquake monitor on the earthquake prospecting field acquisition scene forecasts the quiet period between the continuous natural earthquakes so as to perform the earthquake prospecting field acquisition in the quiet period of the aftershock.
Description
Technical field
The present invention relates to a kind of method of monitoring earthquake, mainly be applicable to the monitoring of earthquake, belong to seismic prospecting data acquisition technique field.
Background technology
Physical prospecting circle does not at present still have the technology that detects earthquake.In other field, disclose in the patent No. " 86107762 " to the prediction of natural and artificially induced earthquake's activity observation with to the preventive protection method of job facilities, its applying date is on November 14th, 1986; Open day is on Dec 2nd, 1987; It is on ground, and underground and ground at least two dark (height) are spent the geophysics of continuous coverage simultaneously, physics, geochemistry, geodetic, biology and microbiology parameter, and wherein at least a parameter is in underground survey; These parameters and reach central station over time and handle; Make amplitude, periodically, frequency spectrum, up-down steepness and each parametric relationship, consider this area geology and rock character again, estimate above-mentioned time series; If at least two kinds of parameters or its variation surpass the empirical threshold value, the alarm signal that earthquake risk takes place can be arranged.
Physical prospecting field acquisition operation needs to grasp in real time the intensity of aftershock, but does not need to protect constantly aftershock, only in several minutes writing times after collection excites, can keep no aftershock or not have intensity surpassing the aftershock that limits.Above-mentioned patent is because of the restriction of its observed pattern, observed parameter; Can only carry out preventive protection to job facilities; And the physical prospecting field acquisition is the operation of implementing that carry out in a more wide zone, interim; This patent is to the earthquake risk signal that gives the alarm takes place, and is can not anticipation fixed with the earthquake strength that takes place.Therefore, this patented technology lacks collection site real-time, applicability, high efficiency, and is also inapplicable in the physical prospecting field.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that existing physical prospecting field and other field exist when the monitoring earthquake; A kind of method of monitoring earthquake is provided, and the present invention monitors the seismic event that earthquake produces, and is utilized in the earthquake period happening with increasing frequency; There is quiet period between the earthquake continuously; The seismic event that the identification earthquake produces quantitatively judges earthquake intensity, the on-the-spot earthquake monitoring of field earthquake prospecting collection; Dope the quiet period that exists between the continuous earthquake, thereby carry out field earthquake prospecting collection in the aftershock quiet period.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of method of monitoring earthquake is characterized in that, comprises the steps:
A, on-the-spot at field earthquake prospecting collection lays a plurality of wave detectors that are connected with seismic instrument, the seismic event that the earthquake that is received by the lasting record of seismic instrument wave detector produces;
B, the seismic event that the identification earthquake produces in background registration;
C, with the seismic wave energy that identifies by the classification of dB scope, obtain monitoring result.
In the said a step; Detection line of elder generation's testing; By surveying the measurement markers place that measured track pitch is embedded in detection line, a plurality of wave detectors are connected with seismic instrument through light/cable with wave detector, the seismic event that the earthquake that is received by the lasting record of seismic instrument wave detector produces.
In the said b step, background registration is meant that the physical prospecting field acquisition does not initiatively excite, and writes down the data of acquisition with seismic instrument, and what seismic instrument write down is the seismic event that external environment condition or natural vibrations form.
In the said b step, identify the seismic event that earthquake produces according to path of seismic wave, whilst on tour, amplitude, frequency, waveform character.
In the said c step, earthquake is divided into " red, yellow, yellowish-white, white " four ranks by intensity, and the corresponding colour code of definition, the different dB scope of the corresponding earthquake instrument screen surveillance gain of each rank colour code.
Employing the invention has the advantages that:
One, the present invention monitors the seismic event that earthquake produces; Be utilized in the earthquake period happening with increasing frequency, have quiet period between the earthquake continuously, the seismic event that the identification earthquake produces; Quantitatively judge earthquake intensity; The on-the-spot earthquake monitoring of field earthquake prospecting collection dopes the quiet period that exists between the continuous earthquake, thereby carries out field earthquake prospecting collection in the aftershock quiet period.
Two, among the present invention, the seismic event that the identification earthquake produces in background registration has been got rid of the seismic event that the physical prospecting artificial excitation produces, and makes the accuracy of monitoring result be higher than existing earthquake detection method far away.
Three, the present invention is through analyzing the aftershock frequency and intensity; With the seismic wave energy that identifies by the classification of dB scope; DB scope through classification can be predicted the quiet period that exists between the continuous earthquake, thereby can carry out field earthquake prospecting collection in the aftershock quiet period.
Four, the present invention is through with the aftershock energy cascade, and makes it corresponding with aftershock intensity colour code, makes collection site have real-time, applicability, high efficiency, makes collection site ability real time discriminating aftershock intensity and aftershock quiet period, instructs and ensure the collection operation in real time.
Five, the present invention can decide the earthquake strength that takes place in anticipation, thereby can carry out preventive protection to job facilities, is particularly useful for the operation of implementing that carry out in zone more wide in the physical prospecting field acquisition, interim.
