Development of LP Wave Discrimination Capability Using LP Strain Instruments
Abstract
The design of strain seismographs capable of detecting long-period seismic motion is in progress. The moving coil-permanent magnet and the direct current-variable capacitance techniques appear to be the most promising and laboratory models of transducers using these techniques are being constructed for testing. Many mines in the Payson, Arizona, and the Las Cruces, New Mexico, area have been visited. Three mines meeting many of the requirements for instrument installation were located and could be used if necessary improvements are made.
