Description
Technical field
The present invention relates to the seismic monitoring early warning system.
Background technology
Earthquake disaster is one of the most serious disaster of facing of the whole world, especially China, and earthquake mostly occurs in densely inhabited district, and that causes suffers heavy losses.If can shift to an earlier date place, time and intensity that predict future earthquake exactly occurs, can save undoubtedly ten hundreds of life of living in the earthquake risk region people, and can take in advance the appropriate precautionary measures, alleviate to greatest extent the destruction of earthquake to facilities such as buildingss, reduce the economic loss that earthquake causes, ensure the stable of society and promote social harmonious development.Although current science and technology is advanced by leaps and bounds, due to " impenetrability " of earth interior, " non-taking place frequently property ", the complicacy of earthquake physical process of violent earthquake, people can't occur in earth's crust 10-20 kilometer depths focus situation and directly observe breeding, so comparatively ripe monitoring technology method and the apparatus of neither one still, can carry out effective forecasting and warning to earthquake so far.Worldwide also without any method, can effectively carry out the short forecasting of earthquake, how extend the prediction about imminent earthquakes cycle, the performance earthquake prediction reduces the effect of earthquake disaster, is the most urgent research topic of earthquake forecast.
Due to the displacement of crustal plate, earth's surface has formed the lake, mountains and rivers.Between crustal plate, displacement forms conflict, causes the geologic structure imbalance finally to cause earthquake to occur, and the eaerthquake damage power depends on the fierce degree of the conflict between the earth's crust.The very long process of up to ten thousand years even that the formation of earthquake will be gone through a century, more than one thousand years, its generation can be accompanied by a series of variations of subsurface geologic structures, there will be many observable signs before shake: the habit that comprises animal is abnormal, the fluctuation of groundwater level, the bubbling of well magic flower, oil slick flower, variable color, the flash of light preceding an earthquake etc.Large tracts of land, occurring in a large number this class abnormal occurrence in the short time, is the signal of coming earthquake the most accurately.But these signals occur how to synchronize with earthquake, be difficult to find in time, during discovery, earthquake often occurs.The digitizing unmanned recording geometry that the earthquake monitoring device that seismological department is promoted at present is comprised of JDF-2 down-hole broadband seismometer and surface soil layer QZ-1A strong motion meter, only underground shock conditions is monitored, before being difficult to find shake, underground geology slowly changes, and especially can't accurately monitor shake cause qualitative change causes lentamente water temperature, change of water quality.
