Description

Technical Field

[0001] This invention relates to the field of plate tectonics, and in particular to a method for constructing a model of the movement trajectory of crustal plates and a method for predicting the movement trajectory. Background Technology

[0002] Plate tectonics refers to the relative movement of one tectonic plate over another on the Earth's surface. In 1968, French geologist Jean-Pierre Le Pichon divided the Earth's lithosphere into six major plates, all of which float on the fluid asthenosphere of the mantle. Plate tectonics causes and shapes the basic features of the Earth's surface, and it also makes the crustal movements at plate boundaries more active, creating areas prone to earthquakes and volcanoes. Furthermore, as two plates gradually separate, new depressions and oceans can appear at the separation points.

[0003] Studying plate tectonics is of great significance for the establishment and maintenance of geodetic coordinate systems, earthquake prediction, volcanic eruption prediction, and the construction of human-made facilities. For example, when planning large-scale projects such as hydroelectric dams, highways, overpasses, sewer systems, and transportation systems, it is essential to prioritize the prediction of potential plate activity.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following will refer to the instruction manual appendix. Figure 1-10 The present invention provides a detailed description of the method for constructing the crustal plate movement trajectory model and the method for predicting the movement trajectory, as well as specific implementation methods.

[0035] Figure 1 This is a flowchart illustrating a method for constructing a crustal plate movement trajectory model according to an embodiment of the present invention. Figure 1 As shown, methods for constructing crustal plate movement trajectory models may include:

[0036] S1, Construct a dynamic spatial magnetic field model of the crustal plate to be measured.

[0037] Specifically, the movement of crustal plates can cause changes in the crustal magnetic field. Therefore, when measuring the relative movement of the crustal plate to be measured, a dynamic spatial magnetic field model of the crustal plate to be measured can be constructed by measuring the changes in the magnetic field at the edge of the crustal plate's outline, thereby constructing a model of the crustal plate's movement trajectory.

[0038] More specifically, multiple magnetometer monitoring stations can be set up along the edge of the crustal plate to be measured. The magnetometer monitoring stations include atomic magnetometers, which are used to measure the magnetic field information of the asthenosphere of the mantle beneath the location of the magnetometer monitoring station. A dynamic spatial magnetic field model of the crustal plate to be measured can be constructed based on the magnetic field information of the asthenosphere of the mantle beneath the location of the magnetometer monitoring station.

[0039] In one embodiment of the present invention, such as Figure 2 As shown, constructing a dynamic spatial magnetic field model for the crustal plate to be measured can include:

[0040] S11, Construct a benchmark space magnetic field model for the crustal plate to be measured.

[0041] Specifically, when constructing a baseline spatial magnetic field model for a crustal plate to be measured, it is necessary to first establish a spatial model map of the plate. During the establishment of this map, magnetometer monitoring stations can be set up along the edge of the plate's outline, with corresponding GPS stations simultaneously deployed. By acquiring the location information of each GPS station along the edge of the plate's outline, the spatial model map is obtained. After obtaining the spatial model map, the initial magnetic field information detected by each magnetometer monitoring station can be simultaneously acquired. Based on the spatial model map and the initial magnetic field information, a baseline spatial magnetic field model for the crustal plate can then be established.

[0042] S12, obtain the dynamic magnetic field information of the crustal plate to be measured.

[0043] Specifically, after obtaining the reference space magnetic field model of the crustal plate to be measured, the magnetic field information (magnetic field magnitude and magnetic field direction) of the mantle asthenosphere under the area where each magnetometer monitoring station is located is obtained from the atomic magnetometers at each magnetometer monitoring station in real time, so as to obtain the dynamic magnetic field information of the crustal plate to be measured.

[0044] S13. Based on the benchmark spatial magnetic field model and dynamic magnetic field information, a dynamic spatial magnetic field model of the crustal plate to be measured is constructed.

[0045] Specifically, based on the baseline spatial magnetic field model of the crustal plate to be measured and the real-time acquired magnetic field information, the dynamic spatial magnetic field of the crustal plate to be measured is constructed, thus obtaining the dynamic spatial magnetic field model of the crustal plate to be measured.

[0046] In one embodiment of the present invention, multiple magnetometer monitoring stations are provided along the edge of the crustal plate to be measured, and GPS stations are provided corresponding to the magnetometer monitoring stations, such as... Figure 3 As shown, a baseline space magnetic field model for the crustal plate to be measured is constructed, including:

[0047] S111: Obtain the latitude and longitude of each GPS station, and construct a GPS station model map of the crustal plate to be measured based on the latitude and longitude.

[0048] S112, obtain the initial magnetic field information of each magnetometer monitoring station.

[0049] S113, based on GPS station model maps and initial magnetic field information, constructs a reference spatial magnetic field model of the crustal plate to be measured.

[0050] Specifically, as shown in Figure 4, multiple magnetometer monitoring stations are set up along the outline edge of the crustal plate to be measured. Each magnetometer monitoring station is simultaneously equipped with a GPS station for verification. The magnetometer monitoring stations are located along the outline edge of the crustal plate region because the asthenosphere beneath the plate is highly mobile in this area, and the monitoring data can more effectively predict the likelihood of earthquakes and volcanic eruptions. Furthermore, the magnetometer monitoring stations monitor the entire outline edge of the plate, providing a wider monitoring range. Since the research focuses on the movement of the crustal plates, covering a large area, a large amount of data is required, and the movement of the crustal plates is slow, requiring very high sensitivity in measuring magnetic anomalies. This embodiment of the invention uses an atomic magnetometer as the magnetic measurement device for the magnetometer monitoring stations. This device offers high sensitivity and is relatively inexpensive, improving the sensitivity of magnetic field information detection while reducing the cost of detection equipment.

[0051] In this embodiment of the invention, when constructing a reference spatial magnetic field model of the crustal plate to be measured, it is necessary to first establish a spatial model map of the crustal plate to be measured. Specifically, the latitude and longitude of each GPS station are calculated and recorded, and the latitude and longitude of each GPS station are uploaded to the spatial magnetic field modeling operation platform. The spatial magnetic field modeling operation platform establishes a GPS station model map using the latitude and longitude of the GPS stations. Based on the completion time of the magnetometer monitoring stations and GPS stations, the atomic magnetometers in the magnetometer monitoring stations measure the initial magnetic field information of the asthenosphere of the mantle beneath the area where each magnetometer monitoring station is located, including the initial magnetic field magnitude and initial magnetic field direction. The initial magnetic field information is transmitted to the operation platform through the GPS stations. The operation platform constructs a reference spatial magnetic field model of the crustal plate to be measured based on the GPS station model map and the initial magnetic field information.

[0052] S2, based on the dynamic spatial magnetic field model, obtains the magnetic anomaly changes of the crustal plate under test.

[0053] Specifically, the dynamic spatial magnetic field model of the crustal plate to be measured can be based on the magnetic field information of each magnetometer monitoring station acquired in real time. The magnetic field information of each magnetometer monitoring station acquired in real time is compared with the corresponding initial magnetic field information to obtain the magnetic anomaly change of each magnetometer monitoring station at the current edge of the crustal plate to be measured.

[0054] In embodiments of the present invention, the magnetic field information includes the magnetic field magnitude and magnetic field direction, and the change in magnetic anomaly is equal to the vector difference between the dynamic magnetic field information and the corresponding initial magnetic field information. The change in magnetic anomaly includes the change in magnetic field magnitude and the change in magnetic field direction.

[0055] Specifically, the initial magnetic field information includes the initial magnetic field magnitude and direction. The atomic magnetometer measures the magnetic field information of the asthenosphere beneath the mantle in the area where the magnetometer monitoring station is located in real time to obtain dynamic magnetic field information, which includes the dynamic magnetic field magnitude and direction. The change in magnetic anomaly of the crustal plate under test is the vector difference between the dynamic magnetic field information and the initial magnetic field information; this change includes the change in magnetic field magnitude and direction.

[0056] S3, obtain the Eulerian vector of the crustal plate to be tested based on the preset geotechnical plate model.

[0057] Specifically, the pre-defined geospatial model can adopt the NNR-NUVEL1A model. The NNR-NUVEL1A model is the international standard model of the International Earth Reference Frame (ITRF). It assumes that the Earth is a perfect sphere, and that the crustal plates are continuous, rigid, and have a constant surface area within a certain range. Therefore, according to Euler's theorem, the movement of the Earth's plates can be considered as rotation around a fixed axis through the Earth's center, and Euler vectors can be used to describe the movement of the crustal plates. Based on the pre-defined geospatial model and the spatial model map of the crustal plate to be measured, the Euler vector of the crustal plate to be measured can be obtained.

[0058] S4. Compare the Euler vector and the change in magnetic anomaly, and construct a magnetic anomaly model of the crustal plate to be measured based on the comparison results.

[0059] Specifically, the change in magnetic anomaly is a vector. The change in magnetic anomaly is compared with the Eulerian vector obtained from the preset geological plate model. That is, the movement and changes of the crustal plate to be measured are compared with the changes in the direction and magnitude of the magnetic field. Based on the comparison results, the magnetic anomaly model of the crustal plate to be measured can be obtained.

[0060] S5, Constructing a trajectory model of the crustal plate to be measured based on a magnetic anomaly model.

[0061] Specifically, the magnetic anomaly model can output the movement information of the crustal plate under test based on the change in magnetic anomaly, and the movement trajectory model of the crustal plate under test can be constructed based on the movement information of the crustal plate under test output by the magnetic anomaly model.

[0062] In one embodiment of the present invention, such as Figure 5 As shown, constructing a trajectory model of the crustal plate under test based on a magnetic anomaly model can include:

[0063] S51, based on the magnetic anomaly model, calculates the moving speed and direction of the crustal plate under test.

[0064] S52. Based on the moving speed and direction of the crustal plate to be measured, the moving trajectory model of the crustal plate to be measured is obtained.

[0065] Specifically, the magnetic anomaly model of the crustal plate under test can calculate the moving speed and direction of the plate based on the changes in magnetic anomaly and the Eulerian vector. This allows for the determination of the displacement of the plate in a certain direction over a period of time. Based on the displacement in all directions, the trajectory of the plate can be plotted, thus constructing a model of its movement. For example... Figure 6 As shown, the position of the crustal plate after its movement over a period of time can be obtained through the trajectory model of the crustal plate under test. The actual displacement of the crustal plate is very small. Figure 6 To facilitate display, its displacement effect is enhanced.

[0066] The method for constructing a crustal plate movement trajectory model according to this invention involves establishing multiple magnetometer monitoring stations along the outline edge of the crustal plate to be measured. Each magnetometer monitoring station is simultaneously equipped with a GPS station as a checkpoint. The magnetic field information of each monitoring station is detected using atomic magnetometers. Atomic magnetometers are highly sensitive and inexpensive, thus saving costs. Based on the magnetic field information detected by the atomic magnetometers and the GPS station model map, a dynamic spatial magnetic field model of the crustal plate to be measured is constructed. The magnetic anomaly changes obtained from the dynamic spatial magnetic field model are compared with the Eulerian vectors obtained from a pre-defined geological plate model. Based on the comparison results, a magnetic anomaly model of the crustal plate to be measured is constructed, obtaining the movement speed and direction of the crustal plate, thereby obtaining the movement trajectory model of the crustal plate. This allows for the monitoring of crustal plate movement, effectively predicting future earthquakes, volcanic eruptions, and other information in a certain region, achieving a preventative effect and having significant implications for human infrastructure construction.

[0067] This invention proposes a method for predicting the trajectory of crustal plate movement.
