Abstract

PURPOSE:To prevent the losing of seismic data while enabling recording of all thereof, by jointly building more than one IC cards while seismic signals generated beyond a memory capacity are stored sequentially into the subsequent IC cards. CONSTITUTION:Vibration of an earth quake caused is detected with a seismograph 1 to be determined with an A/D converter 2 as digital value and then, transmitted to IC cards 3 and 3 jointly built through a switch 9. Then, the same seismic wave signal is stored into waveform recording circuits 4 of the cards 3 and 3. When the card 3 becomes full of records, the base card 3 is separated by the switch 9 from the connection with the converter 2 and seismic wave signals generated afterwards are recorded into the joint card 3 replacing the seismic wave signal thus far stored being erased. This allows the remaining of the same data in other cards 3 disregarding of the destruction of data in the card 3 as caused inadvertently to prevent the losing of the seismic data. This also enables the recording of all data even with greater occurrence of earth quake.
