Scientific paper

To clarify the roles of some parameters on lava flow morphologies, we have developed a 3D numerical simulation model of lava flow and done a number of calculations with various values of parameters. Our preliminary results of calculations suggest that the length of lava flow is, as expected, a function of rheological properties of lava flow, eruption rate, slope angle, and cooling efficiency. The relationship of these parameters and morphologies of lava is not simple, which implies that we could not constrain rheological properties or eruption rate from the length of lava flow alone. On the other hand, the width of lava flow is mainly controlled by yield strength and eruption rate; hence, we consider that the width of lava flow is the most important key to estimate eruption rate.
