Video records allow monitoring lava fountain dynamics at Kilauea volcano. A new correlation analysis method on videos of aligned lava fountains is presented. We found a correlation in the height of lava fountains at aligned vents. A conceptual model of lateral flow of bubbly magma along a feeding dyke is proposed. Time lags between fountain pulses allow indirect constraints about the magma dyke.
