Context

Country: Canada
State/Province: Ontario
Period: THESE USED FROM 1967 TO PROBABLY THE 1980S.
Canada: THESE WERE PART OF A SEISMOGRAPH STATION WHICH WAS ONE OF ABOUT 2 DOZEN THAT WERE INSTALLED ACROSS CANADA IN THE GSC'S NETWORK TO MONITOR ACTIVITY OF THE EARTH'S CRUST TO DETERMINE THE LOCATION OF EARTHQUAKES. THIS INFORMATION WAS USED BY RESEARCHERS STUDYING DYNAMICS OF THE EARTH'S CRUST & PLATE DYNAMICS [REF 2]
Function: USED TO PRODUCE A PHOTOGRAPHIC RECORD OF THE EARTH'S VIBRATION ON A MOVING FILM BY MEANS OF A BEAM OF LIGHT REFLECTED FROM IT'S MIRROR. THE DETECTION OF THE EARTH'S MOVEMENT IS SUPPLIED TO THE GALVANOMETER BY MEANS OF AN ELECTROMAGNETIC CURRENT FROM A SEISMOMETER. [REF 1]
Technical: SEISMOGRAPHS HAVE HAD AN IMPROVEMENT OF SENSITIVITY DUE TO THE RECORDING METHOD - EARLY ONES RECORDED DIRECTLY WITH PENS ON PAPER; THESE GALVANOMETERS RECORDED MOTION OF THE MIRROR ON TO PHOTOGRAPHIC PAPER; & MODERN UNITS RECORD CURRENT VARIATIONS IN THE ELECTROMAGNETS FEEDING INTO A COMPUTER [REF 2]
Area Notes: Unknown
