Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Geological factors such as surface topography and the rate of lava effusion are well-documented drivers that directly influence the dynamics, speed, and emplacement of lava flows at Kilauea.

The analysis

The retrieved papers include specific studies on Kilauea eruptions (e.g., the 2018 lower East Rift Zone eruption and historical flows) explicitly connecting variables like effusion rates, slope angles, and pre-existing topography to lava flow velocities, dynamics, and routing behavior.
