4. 4 Background National Directorate for Geology Objectives Seismological observation in Mozambique started in 1957, after a series of big earthquakes occurred between 1950-1954. 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;

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.
