Abstract: Electromagnetic disturbance is taken as a precursor and effectively used in earthquake prediction, which is very importance for the investigation of earthquake precursors. In this paper, a new electromagnetic disturbance observation instrument (DCRD-1 electromagnetic receiver) is developed and its hardware system scheme, principle, main technical specifications and functions are introduced in details. This instrument can be used to detect a natural electromagnetic disturbance and electromagnetic events with the variation ranging from 0.1 to 10Hz and to record its relevant parameters. Through a series of tests in lab and field, the results show that the technical specifications of DCRD-1 electromagnetic receiver can meet the needs.

Key words: Electromagnetic disturbance, Electromagnetic disturbance reciever, Electromagnetic event, Observation system
