Abstract
PURPOSE: To send out only the data necessary for observation by supervising the vertical vibration components of earthquakes at the base point near abservation points and sending out the horizontal vibration components from the measurement points to the base station only when the vertical vibration components are sensed.
CONSTITUTION: The base point 1 coupled to measurement points 2, 3 by means of transmission circuits 5, 6 for telemeter normally supervises the vertical vibration components of earthquakes being sent out from the measurement points 2, 3. When the vertical components are sensed, a changeover device 14 is changed over via the earthquake judger 15 of the base point 1 and are detected at the measurement points 2, 3 by a transmitter 16, transmission circuit 7 for telemeter, etc., thus the horizontal components of the earthquakes computed from the square sum of the east and west, north and south horizontal components are sent out to the base station 4, whereby the observation of eathquakes is accomplished. Hence, only the data necessary for observation are sent out to the base station through changing over at the base point, whereby the reduction of the transmission lines for telemeter may be achieved.
