2. ZIMBABWE SEISMIC NETWORK
The seismological Network in Zimbabwe started operating in 1959.
Currently the Meteorological Services Department runs 4 seismic stations in Zimbabwe and these include Bulawayo (BUL), Chipinge (CHIPN), Karoi (KRI) and Matopos (MATP).
Data is transmitted via satellite link and GSM for KRI and CHIP
Data analysis is done at Goetz Observatory ,the National Data Centre

5. DATA ANALYSIS IN ZIMBABWE
SEISAN AND GEOTOOL for data analysis
Seiscomp and Seisan software for Data Management.
Seiscomp is allowing us to get more data from regional stations.
Collaborating with CGS in station upgrade and data sharing.
IMS stations providing more data
AfricaArray/IRIS providing more data access.

6. PRODUCTS
Goetz Observatory is the National Data Center (NDC) and archive for earthquake information.
Earthquake reports (seismic maps).
Earthquake bulleting and Catalogs .
Contributes to global seismological research(ISC).
Digital seismic waveform data.
Earthquake hazard assessment.
Public education(general populace, government agencies, students).

7. FUTURE PLANS
The Department is on a drive to try resuscitate the old network.
Zimbabwe is upgrading its seismological network to keep abreast with technological developments in earthquake monitoring
Plans to resuscitate the other seismic stations in Zimbabwe are under way.
Optimizing the operation and maintenance of the network.
Monitor reservoir induced seismicity.
Scientific collaboration with other scientific institutions(seismic hazard, microzonation studies)

9. CHALLENGES FACED IN ZIMBABWE
Data gaps (downtime is highly untenable ).
Vandalism and theft
Funding for station operations.
Brain drain.
Gaps in the downloaded waveforms
Power cuts / generator
Single station location
Personnel
