Bioko - Chapter II

The goal of the second chapter of my dissertation was the assessment of lava flow hazards on Bioko Island (Equatorial Guinea). I created the very first lava hazard maps for Bioko using the probabilistic Q-LavHA model from Mossoux et al. (2016). The model simulates lava flow pathways on a steepest-descent-algorithm from a given vent. Input parameters like flow length and thickness are based on field observations and measurments on a DEM. In summary, most of the cities and villages in the coastal areas of the islands show a low probability for lava flow inundation. The simulated lava flows are mostly channeled by erosional incisions and often blocked / redirected by structural elements such as the graben fault at the summit of Pico Basile.

I presented the results at the IUGG 2023 conference in Berlin (Germany) in July 2023 and the Cities on Volcanoes 12 conference in Antigua (Guatemala) in February 2024. Recently, I submitted a manuscript to VOLCANICA, so look out for the publication! I will upload the presentations and the paper to ResearchGate. My collaborators on this project are Loÿc Vanderkluysen (Drexel), Magdalena O. Chevrel (UCA), and Thomas R. Walter (GFZ). Furthermore, I want to acknowledge all collaborators from our fieldwork campaign on Bioko in Nov / Dec 2022, in particular Oscar A.N. Ela (UNGE), Guillaume Boudoire (UCA), and Christine R. Sealing (Drexel).
