TECHNICAL FIELD OF THE INVENTION
The present invention provides an earthquake precursor monitoring device and a disaster safety confirmation device.
[0002]
[Prior art]
At present, there are many methods of earthquake prediction.
Among them, the world-famous is the VAN method developed in Greece. This is to predict the earthquake by observing the potential difference between two points, that is, the ground current. However, this method has been conducted by several organizations in Japan, and unfortunately, it is unclear as of June 2002 whether it can be put to practical use.
It is no exaggeration to say that unfortunately, there are few things that can be said to be "the decisive hit for earthquake prediction" even in the world.
[0003]
None of the predictions of earthquakes displayed "places where earthquakes might occur" on a two-dimensional map. In other words, the display of weather data is realized by collecting weather information by AMeDAS, but there is no earthquake prediction data equivalent to AMEDAS.
In view of such circumstances, the applicant filed Japanese Patent Application No. 2000-378123. The patent is exactly what this "earthquake is likely to be". In other words, we proposed a system "Kurdas" that indicates where an earthquake "comes".
[0004]
By the way, several proposals for predicting an earthquake using weather data have been made. For example, Japanese Patent Application Laid-Open No. H11-174158 discloses a technique for detecting an earthquake precursor phenomenon using data of temperature and humidity. Japanese Patent Application Laid-Open Publication No. 2000-147140 discloses a technique for predicting an earthquake occurrence based on atmospheric pressure data in "Method and Apparatus for Predicting Earthquake Occurrence". However, none of them has been put to practical use in the world of earthquake prediction as of June 2002.
[0005]
On the other hand, in the "electromagnetic wave noise detection / analysis device" described in Japanese Patent Application No. 7-199262, a device for analyzing the noise detected from the electromagnetic wave and predicting the occurrence of an earthquake (the name is "reverse radio"). Has been proposed.
At least about 20 institutions nationwide are conducting research on seismic electromagnetics, including Professor Masashi Hayakawa of the University of Electro-Communications and Professor Motoki Ikeya of Osaka University. Furthermore, the correlation between electromagnetic phenomena and earthquakes has been studied as "seismic electromagnetics".
In the method using these weather data, a precursor occurs relatively several weeks before the occurrence of the earthquake, compared with the method using other weather data such as electromagnetic waves. More recently, Hiroyuki Inubushi and Prof. Masashi Hayakawa of the University of Electro-Communications reported that nighttime temperatures would rise before the Great Hanshin Earthquake. (May 30, 2002 Earth and Planetary Science-Related Society, “A Consideration on Temperature Change Events Before the 1995 Hyogoken-Nanbu Earthquake”)
[0006]
This event was observed on the night of January 3, 14 days before the Great Hanshin-Awaji Earthquake on January 17, 1995. It was an event that increased by .2 degrees and 2.2 degrees. In addition, an investigation of a case where the temperature rises by 2.0 degrees or more at night over the ten years from 1990 to 1999 reveals that there were only 37 days out of 3651 days. This has a probability of only 1%, and is known to be an event that lasts only a few days in one year. Although the temperature did not necessarily rise with the earthquake on all 37 days searched here, it seems that at least the rise in night temperature and the earthquake have some kind of relationship.
However, the correlation between the earthquake and these data has been controversial and has not been finalized. In this sense, it has been desired to develop a device and a method for objectively examining the correlation.
[0007]
On the other hand, many devices for confirming the safety at the time of a major disaster have been proposed. Some safety confirmation devices using GPS (Global Positioning System) used for car navigation systems have been proposed.
SECOM Co., Ltd. has realized a location information providing and express service called Cocosecom. This is to cope with various problems by grasping the current position of the terminal by carrying a terminal smaller than a mobile phone or holding it in an object.
In addition, KDDI Corporation has added a GPS function to a mobile phone so that the current location of the mobile phone can be ascertained.
[Problems to be solved by the invention]
The present invention has been made in order to improve the above problems, and its purpose is to further improve the accuracy of earthquake prediction by utilizing data from satellites, data from buoys at sea, or data on tide levels, It is to provide a practical device for earthquake prediction.
In addition, a safety confirmation device required at the time of a major disaster is realized based on GPS position information.
[0008]
[Problems to be solved by the invention]
There are two major problems to be solved by the present invention.
(1) Implement a device that displays a "location where an earthquake may occur".
(2) To realize a safety confirmation device that is necessary in the event of a major disaster, especially in the case of a huge earthquake.
Hereinafter, each will be described.
[0009]
(1) It is said that the following three factors are important in the prediction of an earthquake that realizes a display of a place where an earthquake occurs on a map.
It is said that 1, the time when an earthquake occurs, the location where an earthquake occurs, and the magnitude of the earthquake, it cannot be predicted that these three will not be presented in the earthquake prediction. In my opinion, "earthquake location" is probably the most important of these three in disaster prevention. This is because, if you know the location, even if the timing and scale are ambiguous, you can at least “prepare your mind” for disaster prevention officials, businesses and residents in the area.
For example, a business dealing with gas enters into a first-class emergency system immediately after a major earthquake, but if you can anticipate where the earthquake will occur, you can "prepare for your mind" just in case. You can even go one step further and enter an emergency regime. In this way it is possible to contribute to the arrangement of people. Further, physical preparations can be similarly performed. It is an advantage that the people involved in disaster prevention and the residents can also "prepare for the mind."
Conversely, what if the location of the earthquake is unclear? Even if the time and scale are predicted, if the location is unknown, it is impossible to take countermeasures all over the country, and it can be said that there is no way to take countermeasures.
[0010]
Therefore, the present invention pays attention to the “location where an earthquake occurs” and provides an earthquake prediction device and an earthquake prediction method that visually indicate the location of an earthquake that has not been performed in the conventional earthquake prediction. By visually indicating the location of the earthquake, the probability of occurrence of the earthquake in the area can be calculated. Furthermore, the method of providing earthquake prediction information based on the calculated results is also presented.
[0011]
(2) To realize a safety confirmation device that is necessary in the event of a major disaster, especially in the case of a huge earthquake.
In the above-mentioned Cocosecom, it is possible to grasp the position information of an individual. However, there are various problems in grasping a large amount of human positional information at the time of a major disaster. For example, there are the following problems.
1. In a special situation such as a catastrophe, it is humanely possible to grasp the location information of individuals, but the definition of catastrophe is not clear in the first place. It is not accurate to grasp location information.
2. The personal location information is privacy information, but the contradiction that it is necessary only at the time of a major disaster could not be solved. 3. The GPS technology could not be used for safety confirmation information because there was no effective technical idea. .
4. There was no idea of confirming safety based on the fact that individuals moved.
Therefore, the present invention pays attention to these points and provides an apparatus and a method having all the following features in the future.
1. With respect to the problem of whether or not the person carrying the GPS portable terminal is alive, the safety is confirmed using information on whether the GPS portable terminal has moved.
2. Conventional safety information (telephone or Internet) can also be realized seamlessly from a mobile phone terminal. 3. Earthquake prediction technology to identify whether a person carrying a GPS mobile terminal is alive based on location information. In addition to the method of storing a miracle data group (hereinafter abbreviated as GPS trace) of GPS position information as a system before the occurrence of a huge earthquake, in addition to the method of periodically calling a GPS mobile terminal from a safety confirmation device, To provide a mode called "GPS trace mode" in which the terminal side periodically transmits GPS trace data, once turn on the "GPS trace mode" in response to a request from the safety confirmation device, 5. For example, a GPS portable terminal within a radius of 100 km from an epicenter of an earthquake of M6.0 or more automatically automatically moves from the epicenter to the distance from the epicenter. Calculates the, depending on whether or not within the circle and ON the "GPS trace mode". (In this case, triggered by a GPS mobile terminal)
6. In order to reduce communication charges, even if the "GPS trace mode" is ON, information is not sent to the safety confirmation device if it is within, for example, 100 m from the previously grasped position.
7. For a partner whose position does not move more than 100m even after a certain period of time after a major disaster such as an earthquake, the safety confirmation device automatically dials and the safety information can be interactively input by voice.
8. In some cases, the GPS portable terminal is not the original owner. In addition, there is a possibility that the owner may be transferred from the confusion at the time of disaster. Therefore, the GPS mobile terminal is provided with a holder specifying function to specify whether or not the mobile terminal is a GPS mobile terminal holder based on biometrics, and to insert the result into the GPS trace data database in chronological order. Here, the biometrics include voiceprint recognition, fingerprint recognition, iris recognition and the like. For simplicity, the password can be confirmed with a preset password.
[0012]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, each embodiment of the present invention will be described.
[0021]
<First embodiment>
FIG. 1 is a diagram illustrating the configuration of an apparatus for monitoring an earthquake precursor based on satellite data according to the first embodiment of the present invention. The earthquake precursor monitoring apparatus includes a satellite data input unit for inputting data such as a ground surface temperature transmitted from a satellite, a ground surface temperature database for storing ground surface temperature data, and a precursor of an earthquake using the data of the database. Data processing means for performing data processing for detecting an image, image output means for performing a filter processing on a portion of the data where the ground surface temperature rises as a precursor of an earthquake and outputting an image, and as a result of the data processing, there is a precursor of the earthquake And an alarm processing output means for notifying the outside with an alarm when it becomes.
[0022]
Next, the operation will be described.
Satellite data is input by satellite data input means, and temperature data on the ground surface is extracted as an image by data processing means. Generally, nighttime data is preferable because it is easily affected by sunshine during the daytime. However, when data on the ground surface is obtained, the entire area is divided into, for example, 25 meshes of 5 × 5, and each average ground surface temperature is calculated. I do. First, it is important to check if there is a relatively "hot" place in the 25 mesh.
After the relative comparison between the meshes has been performed, a delia with a strong surface heat is searched for while comparing the meshes with each other. Among 25 meshes, a warning such as a warning for one mesh and an alarm for two or more meshes is output to the outside. The output result is received by e-mail, for example. For abnormalities in the mesh, the temperature of the mesh is first averaged, and a warning such as an area of 2.0 degrees or more than the average of the mesh is generated if the area is 5% or more, and an alarm is generated if the area is 5% or more. I do.
Basically, the monitoring is performed by paying attention to the temperature rise from one image. However, by changing the viewpoint, the difference value of the temperature with respect to the image one image before in time (first calculation for each point) ) Is calculated, the averaging process is first performed on the difference value, and it is conceivable to pay attention to a point at which the difference value becomes +1.5 degrees from the averaged difference value.
[0023]
<Second embodiment>
FIG. 2 is a diagram illustrating the configuration of an apparatus for monitoring an earthquake precursor based on satellite data according to a second embodiment of the present invention. The earthquake precursor monitoring device includes a satellite data input unit for inputting data such as sea surface temperature sent from a satellite, a sea surface temperature database for storing sea surface temperature data, and an earthquake precursor using the data of the database. Data processing means for performing data processing for detecting an image, image output means for performing a filtering process on a portion of the data where sea surface temperature rises as a precursor of an earthquake and outputting an image, and as a result of the data processing, there is a precursor of an earthquake And an alarm processing output means for notifying the outside with an alarm when it becomes.
[0024]
Next, the operation will be described. Operationally, it is very similar to the first embodiment. That is, if the ground surface is replaced with a seawater surface, the same processing can be performed as it is.
[0025]
<Third embodiment>
FIG. 3 is a diagram illustrating the configuration of an apparatus for monitoring an earthquake precursor based on offshore buoy data according to the third embodiment of the present invention. An earthquake precursor monitoring device is an offshore buoy data input unit for inputting data such as sea surface temperature sent from a buoy, an offshore buoy database for storing sea surface temperature data and position information, and using data from the database. Data processing means for performing data processing for detecting a precursor of an earthquake, image output means for performing a filter processing on a portion where seawater temperature rises at night as a precursor of an earthquake in the data and outputting an image, and a result of the data processing , An alarm processing output means for notifying the outside with an alarm when there is a sign of an earthquake.
[0026]
Next, the operation will be described. The data obtained is close to that of the second embodiment. However, in the case of the satellite NOAA, which can obtain a thermal infrared image, the data is four times a day, and frequent and convenient timing data cannot be obtained. Therefore, buoys are released on the sea and water temperature data at those buoys are collected. Basically, since it is desired to carry out fixed point observation, a driving force capable of arbitrarily moving east, west, north and south is provided so that the GPS is mounted and the latitude and longitude are fixed. Basically, two orthogonally mounted screw shafts are attached to enable normal and reverse rotation. The propulsion amount is feedback-controlled so as to correct the amount deviated from the fixed point.
For example, by collecting the water temperature every day at 20:00 and the next morning at 04:00, the change in the water temperature can be measured without being affected by the sunshine. It was reported that gas bodies had risen from the sea 11 days before the 1993 Okushiri Island earthquake. (Japan Society for Earth and Planetary Science-Related Research, May 30, 2002, "Occurrence of a gas (cloud) coincident with the aftershock distribution of the 1993 Hokkaido Nansei-oki Earthquake immediately before the earthquake") Shin-ichi Uda) It is assumed that there was a reaction. This embodiment is an apparatus for capturing such an event.
[0027]
<Fourth embodiment>
FIG. 4 is a diagram illustrating a configuration of a device for monitoring an earthquake precursor based on tide level data according to a fourth embodiment of the present invention. The earthquake precursor monitoring device stores tide level data input means for inputting data such as the shoreline tide level, pressure data input means for inputting atmospheric pressure data, an observation information database for storing observation information, and stores position information of observation points. A position information database, data processing means for performing data processing for detecting a precursor of an earthquake using observation information and location information, and a precursor of an earthquake based on a difference between a tide level prediction and an actual tide level in the data. Means for displaying on a map, and / or means for displaying a precursor of an earthquake on a map based on a displacement of an average value with respect to the surroundings in the data, and when there is a precursor of an earthquake as a result of the data processing. And alarm processing output means for notifying to the outside by an alarm.
[0028]
Next, the operation will be described. In the 1993 Okushiri Island earthquake, it was confirmed that the seawater level dropped before the earthquake. (Japan Society for Earth and Planetary Science-Related Studies, May 30, 2002, "Occurrence of a Gas (Cloud) Consistent with the Aftershock Plane Distribution of the 1993 Hokkaido Nansei-Oki Earthquake, Immediately before the Earthquake)" Shinichi Uda) It is a device for capturing events. In other words, if the tide level drops below the predicted tide level, it is possible to suspect the possibility of an earthquake. In addition, the average value is calculated for the average tide level of the observation points within 50 km of the neighborhood, and the difference from the average value (hereinafter, “average difference”) is displayed on a map. The two map display means shown in FIG. 4 display these maps. If the value is lower than expected, or if the average difference with the neighborhood is significantly reduced, the event is highlighted and displayed on the map.
[0029]
<Fifth embodiment>
FIG. 5 is a diagram illustrating a configuration of an apparatus for monitoring an earthquake precursor based on satellite data according to a fifth embodiment of the present invention. The earthquake precursor monitoring device is a satellite data input unit that inputs thermal infrared image data and visible image data sent from a satellite, an image difference processing unit that processes a difference between the thermal infrared image and the visible image, And alarm processing output means for notifying the outside with an alarm when there is a sign of an earthquake as a result of the data processing.
[0030]
Next, the operation will be described. In the 1993 Okushiri Island earthquake, clouds were generated on the 11th before the earthquake, almost equivalent to seawater temperature. (Japan Society for Earth and Planetary Science-Related Studies, May 30, 2002, "Occurrence of a Gas (Cloud) Consistent with the Aftershock Plane Distribution of the 1993 Hokkaido Nansei-Oki Earthquake, Immediately before the Earthquake)" Shinichi Uda) It is a device for capturing events. That is, in the thermal infrared image and the visible image, a cloud generated before the earthquake is captured by performing the difference processing of the images. In principle, the case of Okushiri Island will be explained. First, a visible image V and a thermal infrared image I are prepared. A general cloud is visible at the same density regardless of whether it is a visible image or a thermal infrared image, so that even if the difference is taken, the image almost disappears. However, there is a difference between the clouds that have appeared as a sign of the earthquake when the visible image V and the infrared image I are calculated, and the clouds that have a sign of the earthquake can be captured. By catching in this way, the area is obtained and the alarm is not sounded when the area is equal to or more than a certain value.
[0031]
<Sixth embodiment>
FIG. 6 is a diagram for explaining the configuration of the safety confirmation device at the time of a major disaster according to the sixth embodiment of the present invention. The device for confirming the safety at the time of a major disaster is a basic earthquake information input means for inputting basic information such as the date and time of the earthquake, the scale, the location of the epicenter, and a major disaster recognition means for recognizing that a major disaster such as a huge earthquake has occurred. A client information database storing client information when a major disaster such as a great earthquake occurs, and safety information processing for determining whether to track the client by GPS based on the client information extracted from the database Means, GPS mobile terminal transmitting / receiving means for transmitting / receiving to / from the GPS mobile terminal of the client to be tracked and acquiring GPS position data of the client, and client tracking information for storing GPS data of the client periodically or in an event manner Database and the two databases via the Internet Composed of the Internet processing means can be accessed.
[0032]
Next, the operation will be described. The fact that a large earthquake has occurred is recognized from the basic information of the earthquake (date and time, latitude and longitude of the epicenter, M value, maximum seismic intensity). Immediately after the recognition, a call is made to a predetermined GPS mobile terminal of the client, and location information is added back to the apparatus. Basically, the point is that the GPS trace data is continuously accumulated in order to solve the above-mentioned problem.
[0033]
<Seventh embodiment>
FIG. 7 is a diagram illustrating a configuration of a safety confirmation device at the time of a major disaster according to the seventh embodiment of the present invention. The device for confirming safety at the time of a major disaster is configured in claim 6 with the addition of earthquake prediction information input means for inputting earthquake prediction information.
[0034]
Next, the operation will be described. The basic operation is similar to that of the seventh embodiment. The difference is that by receiving the earthquake prediction information, it is possible to go back to how far before an event such as an earthquake occurs.
As described above, the present invention greatly contributes to solving the following two problems.
(1) Realize the display of the place where the earthquake occurs. (2) Realize the safety confirmation device required in the event of a major disaster, especially in the case of a huge earthquake. We propose and greatly contribute to the estimation of "where" among the three elements of earthquake prediction, "when", "where" and "how many earthquakes". In addition, probability information can be given by introducing an index called probability. Until now, it seems that there have been few practical applications for earthquake prediction, but the equipment and method presented this time has the merit of providing a practical earthquake prediction solution.
Regarding (2), by securing GPS trace data before the earthquake, the safety of many people can be secured.
