My research focuses on physics-based numerical modeling of fluid-driven earthquake sequences. Fluids, such as CO2 and H2O, whether mantle-derived or generated internally through thermal decomposition and dehydration in subduction zones, volcanic regions, or other geological settings (e.g., the Central Apennines), play a significant role in the temporal and spatial distribution of earthquakes and aftershocks. Understanding the physical driving mechanisms of fluids in the subsurface and with the urgent need to transition toward more sustainable energy practices, I also focus on enhancing the use of renewable geothermal energy and advancing carbon capture and storage (CCS) technologies. By studying the migration of of fluids in the subsurface, fault reactivation, permeability changes, and the risk of induced seismicity, I aim to optimize subsurface usage for energy storage and minimize carbon emissions. My goal is to make these technologies more efficient and safe for long-term energy solutions. Through this integration, I contribute to the development of sustainable energy systems that are crucial for combating climate change and reducing reliance on fossil fuels.
