The first Seismological Station was installed in June1957, in Maputo city, and operated by the National Service of Meteorology (Geophysical Department); In 1989 the Geophysical Department was transferred to National Directorate for Geology; Slide 5 5 Seismological Network National Directorate for Geology Is composed by 5 stations: Changalane; Manica; Tete; Nampula; and Lichinga; The transmission of data between these stations including Changalane Broad Band Station (Africa Array Project) and Maputo Centre of Analysis is by GPRS System.
