Machine Learning Looks Anew at Isotope Ratios in Oceanic Basalts

by Paul Asimow 25 October 202224 October 2022

While past attempts to define isotopic endmembers and assign them a geodynamic significance ended in controversy, a machine-learning clustering algorithm offers a solution to this classical problem.

Why Do Arc Volcanoes Deform Less Than Ocean Island Volcanoes?

by Paul Asimow 15 August 202215 November 2022

Volcanic ground deformation is not simply correlated with erupted volume. Researchers propose that high concentrations of magmatic volatiles make systems more compressible and suppress deformation.

A New, Fast Computational Tool for Magmatic Phase Equilibria

by Paul Asimow 11 August 202222 December 2022

Thermodynamic calculations in multiphase, multicomponent magmatic systems can be slow and buggy. A new parallel architecture solves the free energy minimization problem much faster than alternatives.

Machine Learning Helps See into a Volcano’s Depths

by Paul Asimow 27 April 202215 November 2022

How big might future volcanic eruptions be? Crystals carry information to answer this and machine learning methods can visualize and interpret this multidimensional data.
