Exploration of Volcanic Geothermal Energy Resources Based on Rheological Techniques. Fourth Technical Status Report, January 1, 1979-March 31, 1979

摘要

Two tilt-meters have been operated at a site on the Oregon Institute of Technology campus at Klamath Falls, Oregon, since February 13. One strain-meter was installed at the same site on March 11 and the second on March 22. All four instruments have been tested and calibrated and are now fully operational. There have been no major problems except that the first temperature recorders were not sensitive enough and two new instruments have therefore been ordered. Both tilt and strain records obtained so far display semi-diurnal and diurnal oscillations that have the characteristics of solid earth tidal strain fields. Considering the small forcing fields, the records appear to be of a satisfactory quality. (ERA citation 05:000613)
