- PhD Title: Investigating the origins of clustered earthquake swarms in Madagascar and the East African rift: Magmatic versus tectonic drivers
- Year of Completion: 2022
PhD Overview
The central region of Madagascar and the adjacent sectors of the East African Rift is characterized by frequent clustered earthquake swarms, indicating elevated seismic hazard and complex underlying geodynamic processes. This seismicity is commonly attributed to the interaction between tectonic stress, magmatic intrusions, and deeper mantle dynamics; however, the relative contribution of these mechanisms remains poorly constrained. To address this gap, the proposed project will conduct an integrated seismological and geophysical investigation aimed at identifying the primary drivers of earthquake swarm activity in this region.
The research will combine seismic data analysis, geodetic measurements, and geophysical modeling to discriminate between magmatic and tectonic sources of deformation and seismicity. By linking mantle processes, lithospheric stress evolution, and surface earthquake patterns, the project seeks to improve the understanding of rift-related seismic processes. The expected outcomes include improved regional seismic hazard assessment, strengthened disaster risk reduction strategies, and enhanced capacity building in seismic monitoring and data analysis in Madagascar and East Africa, thereby supporting long-term resilience and sustainable development in this understudied region.

About Me
I am a geophysicist and seismologist from Madagascar, and my research focuses on understanding earthquake swarms in Madagascar and the East African Rift. I am particularly interested in finding out whether these earthquakes are mainly driven by tectonic processes, magma movement, or deeper mantle dynamics.
I combine seismic data, geodetic observations, and geophysical modelling to investigate these processes. The goal is to improve our understanding of seismic hazards and contribute to better disaster-risk reduction in Madagascar.
At the same time, I want to build local capacity by sharing seismic and geophysical skills with students and young researchers, particularly encouraging more young women to participate in STEM.
