Embodiment 1

[0018] During the no-seismic safety period, place the earthquake warning device on the eye-level plane, and the geomagnetic needle points to the north and south poles at rest. It can be seen that the pointer basically does not move, and there is no sound and light alarm.

Embodiment 2

[0020] Before the earthquake, the crust was squeezed, the geomagnetic field began to change, and the geomagnetic pointer shifted north-south. Often unstable, indicating that there will be changes in the crust in the near future, attracting attention.

Embodiment 3

[0022] The earth's crust begins to crack, the geomagnetic changes increase greatly, the swing of the geomagnetic pointer increases, and the geomagnetic pointer does not guide north. The instrument starts to alarm, indicating that an earthquake is about to occur. At this time, you should evacuate to a safe area as soon as possible.

Abstract

The invention relates to a method for warning earthquake of a magnetic field tester. According to intense geomagnetic change generated by the extrusion change of earth crust and the instability of drastic geomagnetic change in limited time before earthquake, the magnetic field tester is utilized to convert an intense random swinging or rotating signal of pointers in N pole and S pole into photoelectricity and sound, and emit light and sound to warn and prompt. The method can see the dynamics of a magnetic needle and decide an earthquake signal by watching light and listening. The method can achieve early evacuation, reduce person casualty and property loss, and forecast earthquake of more than 4.5 levels.

Description

technical field [0001] The invention relates to an earthquake warning method for a magnetic field tester, which belongs to the application method of the magnetic field tester. Background technique [0002] At present, due to the uncertainty of earthquakes and the limitation of technical level, earthquake prediction has become a difficult problem in the world. The human and property losses caused by each destructive earthquake have brought huge disasters to mankind. The "6.12" earthquake in China in 2008 is an example. [0003] Most of the currently used earthquake forecasting systems and devices cannot forecast in time, the effect is not ideal, or ordinary residents cannot be notified in time due to other reasons, and the evacuation time is delayed. Contents of the invention [0004] The technical problem solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide an earthquake warning method for a magnetic field tester, w...
