The design of the electromagnetic spider web deployed in the Longmen Mountain fault zone, Sichuan province, is described. Instrument every year to replace the battery life can reach 20 years. In seismically active areas, the principle for deployment is placing multiple groups of wireless transmitting modules. These spider webs of multiple modules are capable of detecting about 30 square kilometers within the scope of magnetotelluric field changes. Each module is usually equipped with an electronic compass for detection of the magnetic anomaly; using a special timer it opens four times per minute for about 5 to 15 s. If the signal is found to be abnormal, it can repeatedly scan many signals per hour. The signal is assessed by the GPRS network, which detects the seismic anomaly in the signal a few days before the earthquake as an early warning. Here, we focus on using ten tactics of ancient China as models for spatially deploying the electromagnetic spider web for further analysis of the quake epicenter. The equipment has low cost and low power consumption, so it is a good method for earthquake prediction.
