Description
Technical field
The utility model relates to earthquake alarm technology and apparatus field, is specifically related to a kind of comprehensive detection seismic sensors warning device.
Background technology
The internal activity of the earth is very active, and its strenuous exercise may cause the change of surface infrastructure and randomness ground Explosion earthquake at any time, and is difficult to be forecast before long period prerequisite by the mankind.The thickness of the earth's crust of continental crust and ocean or diverse location is completely different, and when there is earthquake, focus gives off two kinds of seismic events, compressional wave P and shear wave S, they by respective with different speed to all around propagating, experiencing different time arrives positions different on ground.Current use go deep into drilling technique be also difficult to underground 20km or more depths detect, this greatly adds the difficulty of earthquake being carried out to directly detecting.
China is between circum-Pacific seismic zone and Eurasian earthquake zone, and when Indian Ocean plate dives under the Himalayas, the microplate affecting periphery causes earthquake, as Gansu, west area, the Xinjiang of domestic multiple earthquake.The ground such as Yunnan, Sichuan is positioned on Longmenshan Earthquake Fault Zone, northeast and Hebei Province, the close together of distance circum-Pacific seismic zone, is subject to the impact of its active period.There are Xingtai earthquake in 1966, HAICHENG EARTHQUAKE in 1975, Tangshan Earthquake, Wenchuan earthquakes in 2008 and Ludian scape valley floor shakes in 2014 in 1976 etc. in history.
