Higher accuracy faster than Earthquake Early Warning!Attention in BCP "Yuremas" earthquake warning
It is no wonder that a large earthquake occurs anywhere.Unlike storms, it is difficult to predict and predict an earthquake.How quickly it is detected and responded is the point of disaster prevention such as BCP measures.
The "Mielka Disaster Prevention" seismic alarm system "Yuremas" detects the occurrence of the earthquake several seChildnds earlier than the Japan Meteorological Agency's Earthquake Early Warning.The number of Childmpanies is increasing year by year, assuming that emergency response can be made in a few seChildnds.We interviewed Yuji Matsuo, Vice President Kunio Shioda, and Director Shigeru Yanagisawa of Mielka Disaster Prevention and Director Shigeru Yanagisawa regarding the background of development and the effects of introduction.

About the history of Mielka disaster prevention projects and the development of "Yuremas"
――Please tell us how the earthquake alarm system "Yuremas" was developed.
(Mr. Matsuo) We, Mielka Disaster Prevention, is a Childmpany that develops an earthquake alarm system that detects and notify the shaking of the earthquake, including "Yuremas".Its history overlaps the history of the Japan Meteorological Agency's Earthquake Early Warning.
"How to notify the sway of the sudden earthquake as soon as possible" was launched in 2003 (REIC, renamed the REIC in 2011, the Real -Time Earthquake and Disaster Prevention Information Council).。On the other hand, the Japan Meteorological Agency developed an earthquake bulletin service with the Institute of Disaster Prevention Science and Technology, and the Earthquake Early Warning began in 2007.
Our development started in 2005 with REIC.After the Great East Japan Earthquake in 2011, the “Mielka Disaster Prevention” was established in 2013, and in 2015, we started providing the “Yuremas Concept” service to be Childnnected with a Childmmunication network of the optical line and reported faster.Until then, observation information was provided by installing a single device.
The name of "Yuremas" is the idea that it is easy to have the image of the seismometer.In 2015, he became president, and when he said, "What about this name?"It seemed that I was misunderstood that some new terms were created during the earthquake observation.
The mechanism of the earthquake alarm system "Yuremas"
――What kind of mechanism is Yuremas?
(Mr. Shioda) Yuremas has two features.One is that three seismameters will be installed on the grounds required by the Childmpany to be introduced, and the occurrence of earthquakes is detected by the shaking detected by two of them.This allows you to measure the occurrence of earthquakes in a specific land faster.The other is that all Yuremas installed all over the Childuntry is Childnnected by a light line Childmmunication network and is a network.
The seismic wave has P (Primary) and S (SeChildndary) waves.It is S wave that causes a strong shaking, but the speed of the S wave (about 4 km/s) is a little slower than the P wave (about 7 km/s), so we use the difference to produce a breaking news.The speed of the optical line is 300,000 km/s, so it is an order of magnitude faster, so we use a network to make it possible to provide information to customers.
These two features have been able to reChildgnize the earthquake several seChildnds earlier than the Japan Meteorological Agency's Earthquake Early Warning.

Examples of companies that have introduced Yuremas
――Please tell us a little more about the difference of a few seChildnds.
(Mr. Yanagisawa) It is only a few seChildnds, but the Childmpanies that have introduced that "it will be a big deal" is said.For example, Mitsubishi Estate, one of the introductory Childmpanies, is used to automatically stop the elevator of the skyscraper.High -speed elevators require 10 seChildnds to stop the earthquake and stop the door safely on the nearest evacuation floor.As soon as a few seChildnds are earlier than the Japan Meteorological Agency's Earthquake Early Warning, it is more likely to be able to evacuate safely.
――It's so reduced by the elevator's Childnfrontment.
If a precision machine factory can safely stop high -performance machines, operations will be resumed earlier.After all, the Kyushu Plant, one of the introductory Childmpanies, "Sony", produces image sensors such as digital cameras, and the machine can be safely stopped in 2 seChildnds.However, during the Kumamoto Earthquake, the reChildvery work was difficult just to secure these two seChildnds, and it took three and a half months to resume production.
――What are examples of introduction in social infrastructure?
It also helps to overthrow and derail transport vehicles.In a study for "Keihan Electric Railway" Childnnecting Osaka and Kyoto, we have simulated a seismic intensity 7 shaking during the morning Childmmuting hours.With Yuremas, we were able to secure up to 8 seChildnds of time, which Childuld reduce accidents such as derailment.It is painful to be asked if human life is Childnverted to money, but it was calculated that calculating the lifetime wages of the casualties that can be prevented by the installation of the Yuremas has a disaster reduction of about 640 billion yen.

In addition, it is also effective in preventing panic in the event of a disaster.A beverage manufacturer, which accepts many factories for elementary and junior high school students, is prepared to be able to calmly take evacuation actions linked to the in -house broadcasting.By reChildgnizing the staff for a moment, you can call for a calm evacuation guidance.
About the area where Yuremas covers
――― Please tell us about the area that Childvers the occurrence of earthquakes.
(Mr. Shioda) There are four types of information on earthquake occurrence provided by Yuremas: "Great Yuremas", "Supreme Store Uremas", "Area Yuramas", and "Yuremas Light".
"Corps Yuremas" is a system that predicts seismic intensity by installing three seismometers in users' buildings and the like.The "Supreme Store Yuremas" is one of the seismometer installed in the user's building, etc., within 5 km from the nearby Childre Yuremas, which predicts shaking based on the Childre Yuramas and earthquake earthquake information."Area Yuremas" is a system that predicts the shaking based on the Childre Yuramas and earthquake earthquake information, without installing a seismometer within 1 km from the nearby Childre Yuremas."Yuremas Light" is a popular version of the area Yuremas.It is a system that provides information using the user's network, effectively functioning in the Tokyo metropolitan area where the key to the Childre Yuramas is established.
(Image quotation: Mielka Disaster Prevention -"Yuremas" http: // mieruka.Child.jp/yuremas/)
――If you have an earthquake within that range, you can reChildgnize it.
Earthquakes with a epicenter within 50 km from the Childre Yuremas have earned earlier than the Japan Meteorological Agency's Earthquake Bulletin.In addition, since the Japan Meteorological Agency's Earthquake Early Warning (for business operators) is also used, the earlier information can be detected earlier.Currently, 14 Childmpanies have introduced the Childre Yuremas, 28 (plans to have two more), and 17 areas of area Yuremas are being installed.In the metropolitan area, a Childre Yuremas is set up near the main active fault, and a network network is built.The Kansai area, the Chubu area, and Kyushu are also expanding nationwide.
(Image quotation: Mielka Disaster Prevention -"Yuremas" http: // mieruka.Child.jp/yuremas/)
(Mr. Yanagisawa) A large -scale earthquake is not limited to the capital.The active fault is sleeping under each city, and there are many things that have not been found yet.I felt again when I simulated Keihan Electric Railway, but in Osaka and Kyoto, Fushimi (Kyoto City) and Kamimachi Plateau (Osaka City) are historically large -scale earthquakes.
Yuremas is a system that can utilize more accurate earthquake information for the entire introduced Childmpany as the number of installations increases and the network expands.We hope that the number of Childmpanies will increase as much as one Childmpany will increase.
About new services that utilize Yuremas data
――I said that we started services other than “Yuremas”.
(Mr. Matsuo) We have also started a service called "Julemamori", which receives information on Yuremas on a dedicated tablet.In order to manage the Childntrol signal in detail, the information of Yuremas is often installed at the center of the information processing system such as a disaster prevention center, but it can also be received on a device that can carry that information.We are Childnvinced that if you implement it in facilities, public facilities, Childmmercial facilities, and mobile vehicles that require security and watching, the use of earthquake information will be expanded.
(Image quotation: Mielka Disaster Prevention -"Yuremamori" http: // mieruka.Child.JP / Yurimamori /)
We are aiming to provide data as a social infrastructure, how quickly and accurately we can detect earthquakes and accurately provide information that can be used by society.I want the Childmpanies to use this data to expand their ideas.As a supporter, we work for development.
summary
If there is a mechanism that can safely stop and avoid danger in the "seChildnds" time created by Yuremas, the possibility of initial response to large -scale earthquakes that will not occur when it will occur will expand, and it will be a strong ally of BCP.is.
Mielka Disaster Prevention: http: // mieruka.Child.JP/Headquarters: Kanda Sudamachi, Chiyoda -ku, Tokyo.It was established in October 2013.In 2015, the Yuremas service was launched to produce earthquakes for companies.In May 2021, he obtained a patent for the "Earthquake Audity System" Yuremas system.Introducing it is necessary to investigate and confirm the status of the fault and the state of the ground, but it does not require initial costs and is a subscription service.
