Geomagnetism and earthquake forecasting observer

The invention discloses a geomagnetism and earthquake forecasting observer. Since ancient times, earthquakes brought endless pains for human beings again and again, and although human beings continuously explore and research, a more accurate method for forecasting in advance is not found. With the references of mass data and practical observations and researches and through the method of seeing through the appearance to perceive the essence, the invention proposes to forecast the earthquake by using the change of geomagnetism, and the observer is supposed to be installed in houses, schools, hotels, hospitals, and the like in any region within China. When plates of the earth begin to move, the geomagnetism changes, and a compass changes correspondingly. When an alarm lamp flares, people observe a common compass, the higher degree the compass swings left and right, the larger the earthquake magnitude is, otherwise, the smaller the earthquake magnitude is. The three elements, i.e. time, place and earthquake magn
