An Earthquake Early Warning System

Abstract

The invention belongs to the technical field of earthquake early warning, and particularly refers to an earthquake early warning system; it includes several earthquake monitoring network points, and an earthquake early warning device is arranged at each earthquake monitoring network point. The earthquake early warning device includes a deep pit dug from the ground to the ground, and several bearing The lower end of the column is inserted into the bottom of the deep pit, and an inner pipe, an intermediate pipe and an outer pipe are arranged in the deep pit, and two water flow channels are arranged at intervals up and down along the pipe wall in more than four directions distributed along the circumferential direction on the pipe wall of the outer pipe The connecting port is provided with two water flow channels respectively connecting the connection port of the water flow channel and the inner cavity of the inner pipe between the outer pipe, the middle pipe and the inner pipe, and a hydrophone is arranged between the two valves in each water flow channel, and the inner Hydrophones are installed at the intersections of water flow channels in the pipe, and monitoring equipment for early warning of earthquakes is provided in the monitoring room according to the signals sent by the hydrophones; the invention can pre-warn the magnitude and location of earthquakes to reduce casualties and property losses.

Description

Technical field: [0001] The invention belongs to the technical field of earthquake early warning, in particular to an earthquake early warning system. Background technique: [0002] Earthquakes are caused by the continuous movement and changes of the earth, gradually accumulating huge energy, and the lithosphere in a certain fragile zone of the earth's crust suddenly ruptures or causes the dislocation of the original fault, and the earth's internal energy is strongly released in the form of seismic waves come out, thus causing the phenomenon of ground vibration within a certain range. [0003] At present and for a long time in the future, it is impossible to predict the arrival of earthquakes. The current earthquake early warning is to use the characteristics that the seismic wave propagation speed is lower than the electric wave propagation speed after the earthquake occurs, and give early warning to places where the seismic wave has not yet arrived. Generally speaking, t...
