Seismic Instrument Development

Abstract

The overall objective is to continue the design, development, test, and evaluation of improved seismic sensor systems. 1.1 Strain-Inertial Seismometer (SIS) Objectives. Two prototype SISs were designed, fabricated, and subjected to initial test and evaluation. The SIS was being developed in order to investigate the potential use of the combined outputs of collocated stain and inertial sensors to enhance signal-to-noise ratio. If the development is successful and if a practical SIS system can be implemented, then the instrument could be used in lieu of small arrays of inertial instruments to record high quality seismic data in seismically noisy areas. Two Model 4400o Seismometers (one engineering model and one prototype had been designed, fabricated, and subjected to bench level and borehole testing. The Model 44000 design objectives have been: meet or exceed the performance of the KS36000 Seismometer; not exceed the cost of the KS36000; design to install in a 4-inch diameter borehole up to 15 degrees off vertical; design to reduce complexity of installation, operation, and maintenance procedures; and take maximum advantage of design concepts already developed for the KS36000 system.
