Dr Brassnavy Manzunzu

Senior Lecturer

I am a seismologist. I hold a B.Sc. (Hons) degree from the University of Zimbabwe, an M.Sc. in Geophysics from the National University of Science and Technology (NUST) and a Ph.D. from the University of the Witwatersrand in the Republic of South Africa. In 2023, I joined the NUST as a Senior Lecturer. I have published more than 20 papers in internationally referred journals. My research interests are in seismology, seismic hazard, and application of seismic methods to geotechnical engineering. I have collaborated with several local and regional scientists to understand the seismotectonics of Southern Africa. I have supervised several B.Sc. and M.Sc. students. I have presented several of my works at local, regional and international conferences. I have work for the Zimbabwe Meteorological Services where I rose through the ranks to become the Seismology Manager. I have also worked for the Council for Geoscience in the Republic of South Africa where I participated in several projects related to seismology and seismic hazard assessments in Africa. Amongst other, these projects involved commercially assessing seismic hazard and risk for sites of critical engineering structures such as dams, bridges, power stations pipelines, buildings etc. In addition, I have worked on several research projects including the development of the South African seismic hazard map, and the development of microzonation models for several cities in South Africa. Lastly, I enjoy learning new things, gaining new skills and becoming proficient in tasks or studies that I already understand. My vision for Zimbabwe is to seeing seismology and geophysics research in advance to its best for the safety and sustainable development of Zimbabwe and her Citizenry.

Courses taught:
1. Undergraduate course: Theory of Seismology, Seismic
