Abstract:

This work provides an up-to-date overview of modern instruments used in earthquake seismology as well as a description of theoretical and practical aspects of seismic instrumentation. The main presentation describes the Zambian Seismic Networks [ZSN].This network has undergone three major phases in its digitization processes from single analog station to the current three components: - Choosing and installing equipment for seismic stations - Designing and setting up seismic networks and arrays - Maintaining and calibrating seismic instruments, digitizers, seismic recorder, communication systems and Software used for seismic stations and networks. The aim of the network is to monitor seismic activities in Zambia and surrounding areas to inform the Government of the Republic of Zambia on earthquake activity. The sensor types installed include the STS1/2 with Q330 digitizers interfaced with the CTBTO GCI. The rest of the stations are either Guralp Tellurium, Nanometrics with all digitized, Reftek 130s, some Guralps compact types with inbuilt DM24 digitizers which operates using SCREAM software.
