2019 The Release of the GEM Global Active Faults Database and Global Seismic Hazard Map

04 Feb 2021 | Contributor(s): Richard Styron

In late 2018, the Global Earthquake Model Foundation (GEM) released the initial version of several major products relating to seismic hazard and risk, including the Global Seismic Hazard Map, the Global Seismic Risk Map, and the Global Active Faults Database. Though these are intended primarily...

2019 HeFESTO: A tool for exploring Earth's physical properties and their effects on mantle dynamics

04 Feb 2021 | Contributor(s): Carolina Lithgow-Bertelloni, Lars Stixrude

The minerals that exist at the extreme pressure and temperature conditions of the mantle and their physical properties determine the dynamics of the mantle. Both are also critical for comparison with seismic observations that put constraints on our knowledge of mantle structure and...

2019 Introduction to Quagmire

04 Feb 2021 | Contributor(s): Louis Moresi, Ben Mather, Romain Beucher

Quagmire is an open source, parallel python module for modelling surface processes and landscape evolution. It comes from the Underworld geodynamics group and has many common design patterns to Underworld. For starters, this is not an out-of-the-box landscape evolution code — it is instead...

2018 Introduction to thermal-mechanical lithosphere models with surface processes

04 Feb 2021 | Contributor(s): Louis Moresi, Romain Beucher

Surface processes including erosion, transport and sedimentation have the potential to strongly influence crustal and lithospheric deformation whether passively, through isostatic response, or more actively by affecting the thermal structure, the potential energy field, and / or the local stress...
