Features and functions of the direct dragon
■No line required, no radio waves required
Nadir Dragon does not require earthquake information from the Japan Meteorological Agency, as the device itself is an earthquake P-wave sensor. Even if you don't have an internet connection or can't receive FM radio waves, you can know about earthquakes before they hit. There are various ways to use it, including preventing secondary disasters in disaster-stricken areas, using it in remote mountainous areas, using it at construction sites, and using it overseas. Normally, a rotating light or sound device is connected to the direct dragon, and a speaker is used to notify the alarm.
■Supports direct earthquakes
Areas within a radius of approximately 30 km from the center of the epicenter will not be able to receive Earthquake Early Warnings in time, and will be hit by sudden, large shaking before the Earthquake Early Warnings are issued. Knowing an earthquake in advance, even if only for a few seconds, will change the way you think about the upcoming earthquake. This way of thinking will help you to suppress your agitation, make the right decisions, and ensure your own safety.
Even in the case of a major earthquake directly below the earthquake, there is a time period of 4 to 10 seconds from the arrival of P waves until the maximum seismic intensity that can cause damage is reached. "Next Dragon" detects a direct earthquake within one second after the P wave arrives, and notifies you of the earthquake occurrence. For earthquakes that occur directly below the ground, which is the limit of emergency earthquake early warning, we will use the "Directly Under Dragon" system to notify everyone of the occurrence of an earthquake.
■ Eliminate false alarms as much as possible
Earthquake early warnings always carry the possibility of false alarms. In order to eliminate such false alarms as much as possible, it is necessary to observe P waves at locations where emergency earthquake early warning receiving terminals are installed. P waves can be observed regardless of the occurrence of an earthquake, so if Dragon directly below observes a P wave, there is a high possibility that it is not a false alarm.
Utilizing this principle, instead of broadcasting in the building or controlling equipment only with the warning signal from the earthquake early warning, we start emergency broadcasting and equipment control only when we receive the warning signal from the Dragon directly below, thereby eliminating the possibility of false alarms. eliminate.
■Improve the accuracy of predicted seismic intensity
In the 2011 Great East Japan Earthquake, the predicted seismic intensity in each area in the Earthquake Early Warning was significantly lower. There are various reasons for this, but the main reason is that the earthquake early warning system underestimated the magnitude. Nakyu Dragon instantaneously analyzes the P waves it receives independently from earthquake early warnings and calculates the predicted seismic intensity. The accuracy can be improved by using not only the predicted seismic intensity from the Earthquake Early Warning but also the predicted seismic intensity from the Dragon directly below.
