Which risk increases when basaltic lava eruption rates diminish?

💡 Explanation

The risk of lava channel avulsion increases because lower flow rates reduce shear stress at channel margins and volumetric throughput, reducing stability, therefore avulsion becomes more likely, rather than stable channel flow further downstream.
