Geophysical Strain And Tilt : Measurement Methodology And Analysis Of Data, Robert Mackay
Geophysical Strain And Tilt : Measurement Methodology And Analysis Of Data, Robert Mackay
Dissertations and Theses
Tilt and strain meters were installed on the Portland State University campus in the summer of 1982 and data was collected for 4 months. Instrument selection, operation, installation and performance are discussed.
Suggestions that could enhance data quality and data collection efficiency are presented.
An analysis procedure is suggested and an example of this procedure for an interval of data is discussed. The influence of the temperature, pressure, rainfall and solid earth tides on the signal is investigated, as well as the correlation between similar channels of the different tilt instruments. The temperature, rainfall and solid earth tides were all …
