A brief description of BMR portable seismic tape recording systems

Abstract

Current methods of interpreting seismic data from earth-quake or explosion sources in terms of geological structures use both the kinematic and dynamic information in the data. This requires that the characteristics of the systems used for recording and analysing ground motion be well known, and in recent years this requirement has been allied with the many developments in electronic engineering and tape recording to produce a generation of field equipment which is both portable and rugged (Dibble, 1964; Mereu & Kovach, 1970; Muirhead & Simpson, 1972; Crowe, 1973; Long, 1974). Most of this equipment has been designed and built by research groups and therefore was not easily available for purchase. Those systems which were available commercially were generally very expensive for the tasks required of them.
