ABSTRACT:
This invention provides method and apparatus to predict accurately volcanic eruptions or the occurrence of earthquakes without the use of a seismometer or an incline level meter. The apparatus includes a neutron sensor, a counter and a displaying device to indicate an integrated count number or changes in count number of neutrons radiated from the earth's magma with the prediction being performed on basis of the changing count or integrated count number for a given period of time.
