Seismology and Geophysics
Responsible for the installation and maintenance of seismic network and early warning systems for 24 hours daily monitoring
INTRODUCTION
Is responsible for the installation and maintenance of seismic network and early warning systems for 24 hours daily monitoring of earthquakes, conducts seismic hazard assessment, and engineering seismological studies (site effect characterization). It undertakes geo-hazards mapping/risk assessment, delineation, and characterization of earthquake faults zones (lines) for the preparation of relevant maps and reports to assist with national development.
It carries out disaster risk reduction education, sensitization campaign, earthquake early warning and evacuation drill exercises.
FUNCTIONS
- Conducting seismic refraction, resistivity, airborne surveys and ground magnetic surveys for geoscientific studies including mineral exploration and conduct other ground surveys for the preparation of relevant reports to assist with national development.
- Earthquake monitoring, installation and maintenance of early warning systems.
- Conducts seismic hazard assessment and engineering seismological studies (Ambient noise measurement to determine H/V spectral ratio (HVSR)), geo-hazards mapping / risk assessment, characterization of earthquake faults for the preparation of relevant maps and reports to assist with national development, disaster risk reduction.
- Education and sensitization campaign on earthquake as well as conducting early warning and evacuation drill exercises.
