Effects of internal rheology and surface cooling on the emplacement of lava flows

Lyman, Aaron; Kerr, Ross; Griffiths, Ross

Description

The emplacement dynamics of lava flows is modeled using a combination of laboratory experiments and theoretical scaling analyses for the case where a fixed volume of lava is rapidly released and spreads as a horizontal, two-dimensional flow. We focus on the processes that determine the final runout length of the lava, including the growth of a crust due to surface cooling and the presence of an internal yield strength. We show that solidifying flows with no internal yield strength first spread...[Show more]
