DEEP-WELL RESEARCH.
Abstract
The deep-hole triaxial seismometer array was installed and briefly operated at the test site near Grapevine, Texas. It will be moved to a site near Apache, Oklahoma and operated routinely. Analysis results showed that the energy in teleseismic signals recorded at depth agreed closely with theory for the first 5 seconds of the signal, but agreed less as a function of time after the onset of the signal. Inverse filter design was partially successful. The limitation in the design was found to be the dynamic range of the recorder used to acquire the data; measurements made in the future will have adequate dynamic range to allow design of the filters. An off-line computer program was completed to unpack the field recordings. The program is highly efficient in that the data are not demultiplexed except at the final output. (Author)
