[0054] The present application provides a method for broadcasting earthquake warning messages. Figure 1is a schematic diagram of the process of an earthquake warning message broadcasting method provided by an embodiment of the present application, with reference to Figure 1 , the earthquake early warning message broadcasting method is described as follows:

[0055] Step 101, obtaining the epicenter coordinates, focal depth and epicenter magnitude of the target earthquake.

[0056] Step 102, based on the epicenter coordinates, focal depth and epicenter magnitude, obtain the historical earthquake regional magnitude distribution information of each historical earthquake closest to the target earthquake.

[0057] Exemplarily, step 102 may include:

[0058] Obtain the historical epicenter coordinates, historical focal depths, historical epicenter magnitudes of multiple historical earthquakes, and the corresponding regional magnitude distribution information of multiple historical earthquakes.

[0059] Multiple historical earthquakes are clustered according to historical epicenter coordinates, historical focal depths and historical epicenter magnitudes to obtain multiple cluster centers.

[0060] Calculate the distance from the target earthquake to each cluster center.

[0061] The cluster corresponding to the minimum value of the distance from the target earthquake to each cluster center is defined as the target cluster.

[0062] The historical earthquake regional magnitude distribution information of each historical earthquake in the target cluster is determined as the historical earthquake regional magnitude distribution information of each historical earthquake that is closest to the target earthquake.

[0063] Specifically, the above cluster center can be expressed as {epicenter coordinates, focal depth, epicenter magnitude}. Therefore, when calculating the distance from the target earthquake to the cluster center, it can be determined based on the similarity between the epicenter coordinates, focal depth, epicenter magnitude of the target earthquake and the cluster center.

[0064] Step 103, determining the theoretical radius of different earthquake types based on the magnitude distribution information of each historical earthquake region.

[0065] Exemplarily, step 103 may include:

[0066] For each historical earthquake region magnitude distribution information, the distance between the boundary of each earthquake type in the historical earthquake region magnitude distribution information and the historical epicenter coordinates in the historical earthquake region magnitude distribution information is obtained, and recorded as the undetermined theoretical radius of each earthquake type.

[0067] The maximum value among the undetermined theoretical radii corresponding to each earthquake type is determined as the theoretical radius corresponding to each earthquake type.

[0068] Specifically, since the magnitude area in the magnitude distribution information of each historical earthquake area is not a perfect circle, there will be multiple undetermined theoretical radii. Taking into account the local geological structure and in order to avoid casualties, the maximum value of these undetermined theoretical radii is defined as the theoretical radius corresponding to each earthquake type.

[0069] Step 104, based on the theoretical radius corresponding to each earthquake type, determine the magnitude areas corresponding to different earthquake types centered on the epicenter coordinates.

[0070] Exemplarily, step 104 may include:

[0071] With the epicenter coordinates as the center, circles are drawn with the theoretical radius corresponding to each earthquake type as the radius to obtain multiple concentric circles.

[0072] The smallest circle among multiple concentric circles and multiple circular rings are defined as multiple magnitude areas; the earthquake type corresponding to the smallest circle is the earthquake type corresponding to the magnitude of the epicenter; the severity of the earthquake types in the multiple circular rings decreases from the inside to the outside.

[0073] In some specific embodiments, Figure 2 As shown, the theoretical radius corresponding to each earthquake type includes: r1, r2, r3 and r4; the magnitude regions include I, II, III and IV. Assume that the earthquake type in region I is a large earthquake, the earthquake type in region II is a moderate-strong earthquake, the earthquake type in region III is a weak earthquake, and the earthquake type in region IV is a small earthquake. Then, the theoretical radius corresponding to a large earthquake is r1, the theoretical radius corresponding to a moderate-strong earthquake is r2, the theoretical radius corresponding to a weak earthquake is r3, and the theoretical radius corresponding to a small earthquake is r4.

[0074] Exemplarily, the earthquake types include, from large to small: major earthquakes, moderate-strong earthquakes, weak earthquakes and tiny earthquakes; among them, the epicenter magnitude corresponding to a major earthquake is greater than or equal to magnitude 7, the epicenter magnitude corresponding to a moderate-strong earthquake is 5.5 to 6.9, the epicenter magnitude corresponding to a weak earthquake is 2.4 to 5.4, and the epicenter magnitude corresponding to a tiny earthquake is less than 2.5.

[0075] Step 105, sending earthquake warning messages to users in the corresponding magnitude areas in order of severity of the earthquake types from large to small.

[0076] Exemplarily, step 105 includes:

[0077] The magnitude areas with the earthquake type of micro-earthquake are screened out in the magnitude areas to obtain the remaining magnitude areas.

[0078] No earthquake warning message will be sent to the earthquake magnitude area where the earthquake type is small.

[0079] For the remaining magnitude areas, earthquake warning messages are sent to users in the corresponding magnitude areas in order of the severity of the earthquake types from large to small.

[0080] Specifically, in order to ensure the efficiency of message sending, according to the maximum number of threads processed by the base station processor, the same number of messages are synchronously sent to users in the earthquake zone. In addition, in order to ensure the timeliness of the messages, the method also includes:

[0081] Get the location of the sending base station;

[0082] Construct a vector pointing from the location of the base station to the location of the earthquake center;

[0083] For users in the same magnitude area, earthquake warning messages are sent sequentially according to the direction of the vector.

[0084] Exemplarily, the earthquake early warning message broadcasting method further includes:

[0085] After sending an earthquake warning message to users in any magnitude area, the earthquake warning message will be sent repeatedly multiple times according to the preset time.

[0086] Specifically, in order to ensure that the warning message can be accurately sent to users in the earthquake-magnitude area, it is necessary to send the earthquake warning message repeatedly to avoid casualties as much as possible.

[0087] The above earthquake early warning message broadcasting method obtains the magnitude distribution information of the historical earthquake area closest to the target earthquake based on the data of the target earthquake, and determines the theoretical radius of different earthquake types based on the magnitude distribution information of each historical earthquake area, so that the calculated theoretical radius is more accurate while reducing data calculations, and finally divides the magnitude area according to the theoretical radius, and finally sends earthquake early warning messages to users in the magnitude area in turn according to the severity of the earthquake type, so as to ensure that earthquake early warning information is pushed to users quickly and avoid a large number of casualties. In addition, the more accurate calculation of the theoretical radius can make the earthquake early warning more accurate, avoid the situation where the actual earthquake level is higher than the push level, and avoid serious consequences.

[0088] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
