A new study led by Tsinghua University reveals that powerful undersea currents, known as turbidity currents, are far more prevalent than previously understood. These currents, capable of damaging crucial internet cables, were once believed to only occur in steep underwater environments. However, researchers have discovered they can also form in calmer settings like lakes and reservoirs. This expanded understanding of turbidity current formation suggests a heightened risk to the global internet infrastructure. The research provides new insights into the behavior of these flows, which reshape ocean floors and disrupt connectivity. The findings emphasize the need for improved monitoring and protection of subsea cables worldwide. Further investigation will focus on predicting and mitigating the impact of these increasingly common events.
