SCUBAS: A python-based numerical model to estimate electrical surges in submarine cables during geomagnetic disturbances

Submarine cables are crucial for global internet connectivity, but their vulnerability to extreme space weather events remains uncertain. Understanding and mitigating this risk is essential for maintaining reliable communication infrastructure. This study aims to develop a computational model to assess the induced voltages in submarine cables during geomagnetic disturbances. The model, implemented in Python, utilizes parameters such as ocean and Earth conductivity, cable length, and magnetic observatory data to estimate induced voltages. By providing a user-friendly software tool, researchers and engineers can evaluate the impact of geomagnetic events on submarine cables. Through theoretical explanations and practical demonstrations, this study enhances our understanding of submarine cable behavior under extreme space weather conditions. Ultimately, this research contributes to the preparation and mitigation of potential disruptions to submarine cable systems, ensuring the resilience of global communication.
