Lava flow rheology: A comparison of morphological and petrological ...
2013年12月15日 · Here, we test the planetary approach using a terrestrial basaltic lava flow from the Western Volcanic Zone in Iceland. The geometric parameters required to employ Jeffreysʼ …
In this review I focus on the flow of lava on the surface (neglecting the equally interesting dynamics beneath the surface, which force the eruption of magma). In Section 2, I provide …
Investigating lava flow rheology using video analysis and …
2012年12月1日 · Lava rheology is a major control on lava flow behavior and a critical parameter in flow simulations, but is very difficult to measure at field conditions or correctly extrapolate from …
Numerical simulation of lava flows based on depth‐averaged equations …
2005年3月5日 · In this work we propose a simplified 2D model based on the conservation equations for lava thickness and depth-averaged velocities and temperature which result in …
Evaluating lava flow propagation models with a case study
2021年10月5日 · During early stages of eruption crises, the most useful lava flow propagation equations utilize readily determined parameters and require fewer a priori assumptions about …
Three dimensional modelling of lava flow using Smoothed …
2011年6月1日 · The paper describes the use of the grid-free Smoothed Particle Hydrodynamics (SPH) method to investigate lava flow from volcanic eruptions using real three dimensional …
Post‐emplacement cooling and contraction of lava flows: …
2017年1月26日 · Lava flows contract as they cool, causing progressive subsidence of the flow surface. Here we study this process by measuring and modeling the deformation of emplaced …
A review of mass and energy flow through a lava flow system
2017年7月27日 · Here, I review empirical, physical, and experimental models designed to understand and link the flow of mass and energy through a lava flow system, as well as …
Evaluation of flow rate for a one‐dimensional lava flow with power‐law ...
2009年11月25日 · We consider a horizontally unbounded, isothermal layer of lava, flowing down a slope driven by the gravity force. We consider a constitutive equation where shear stress is …
Lava flows (Chapter 5) - Modeling Volcanic Processes
One type of numeric model aims to apply and link equations that describe lava flow cooling rates, rheology, and dynamics to simulate lava flow spreading. Generally applied to basaltic lava flow …
