Definitions

  • the invention relates to an arrangement for the short-term and largely exact prediction of earthquakes by determining and measuring seismic ground vibrations.
  • the invention is based on the object of proposing an arrangement which makes it possible to predict earthquakes shortly and as precisely as possible in order to be able to take the measures mentioned in good time.
  • the ultrasound waves received by the sensors can be transmitted directly or modified and, if necessary, can be transmitted to the evaluation device.
  • the signals are transmitted from the sensors or from the devices assigned to them to the central evaluation device either wirelessly or by means of electrical lines.
  • the invention is based on the knowledge that it is known from a number of animals, especially those who live in earth caves, to leave their hiding angles or dwellings shortly before an earthquake and to flee to the surface of the earth, and indeed to a point in time when seismographs do not yet register any ground movements or vibrations. But not only on the surface of the earth or in caves or the like, live animals, but also animals living in the water show an abnormally changed behavior of great agitation and panic before earthquakes occur. Observations of this kind have been made at various places on earth and have been for a long time. Corresponding observations of the previously described behavior of animals in China were the reason why the strong earthquake in the Liaoning Province in 1975, timely measures were taken to warn the population and cause them to take to safety. A wide variety of assumptions have been made as to what could be the cause of the behavior of the animals.
  • the inventor's findings amount to the fact that in the case of rock deformations as a result of strong pressure effects, the crystal structure comes into high-frequency vibrations, as a result of which the rock superficially emits ultrasonic waves, which are then the cause of the behavior of the animals mentioned. This is also quite understandable because animals have organs that allow them to perceive such vibrations, while human hearing is only able to perceive sound waves with frequencies up to about 20 kHz.
  • the ultrasound waves are the sought criteria, with the aid of which it is possible to make the necessary determinations by means of the arrangement according to the invention, in order then to be able to evaluate them and use them to trigger an alarm.
  • the ultrasonic sensors 11 are embedded in an earthquake-prone area according to a predetermined grid or according to geological conditions, or are firmly connected to the surface of the earth where there is solid, deep rock.
  • the signals of high-frequency vibrations received by the sensors 11 in the range above approximately 20 kHz are transmitted either directly to the evaluation device 12 or with the interposition of a device 13 which modifies and / or amplifies the signals for the purpose of better transmission.
  • the evaluation device 12 determines the frequency and the intensity of the ultrasonic vibrations as well as the approximate position of the epicenter of the impending earthquake and, if predetermined criteria are met, sends a corresponding signal to the alarm device 14, which then automatically triggers warning signals in the entire area concerned to inform the affected population.
  • the signals can be transmitted from the sensors 11 or the devices 13 assigned to them to the central evaluation device 12 either wirelessly or by means of electrical or similar lines.
  • the alarm device is expediently set up in such a way that it transmits signals to a large number of stations distributed in the affected area, by means of which gas lines are blocked off in places or power plants, factories or the like are shut down immediately in order to avoid disasters which may be caused by them . If recordings of the evaluation device are available over a longer period of time, further conclusions can be drawn from them, which can make the earthquake forecast even more precise.

Abstract

Agencement permettant de prévoir à court terme les tremblements de terre par l'observation et la mesure des oscillations sismiques du sol au moyen de capteurs ultrasoniques (11) sensibles à des oscillations haute fréquence dans la plage excédant environ 20 kHz. Ces capteurs sont enfouis dans le sol ou reliés à celui-ci et couplés avec un appareil d'évaluation (12) permettant de déterminer la fréquence et l'intensité des oscillations de la source sonore.
