Bridging the Gap: How Virtual Reality is Helping the Next Generation of Geoscientists

Phillip Ruscica and edited by Andreia Hamid September 16, 2026

Deciphering Earth’s geological history is no easy feat. For undergraduate students beginning their journey in geology, identifying a rock and drawing connections with relevant geodynamic processes occurring over millions of years can be a challenge. In this week’s blog post, Phillip Ruscia explains how virtual reality (VR) and the High Immersion Virtual Experiences (HIVE) research lab at the Unive ...[Read More]

Travel across the globe and you will see landscapes change along the way. But what if the same were true inside Earth? What if the landscapes we see on the surface also exist deep within? In this week’s Geodynamics 101 post, Ankit Barik, Assistant Research Scientist at Johns Hopkins University, explores the hidden topography deep inside our planet and why do they matter. The only fluid part of the ...[Read More]

If you have ever tried to draw a geological cross-section under a fantasy map, Homer is surprisingly cooperative (and if you remember my Middle-earth geology post, you already know I live for this). The Odyssey is full of real places and real people—Troy, Mycenae, Sparta—stitched together with storms, monsters and divine interventions that would make any structural geologist reach for a stress ten ...[Read More]

Modeling the full spectrum of observed seismicity: Insights from friction laws, fault instability, and fault-zone mechanics

Navid Kheirdast and edited by Alexis Gauthier June 17, 2026

Introduction Despite advances in our understanding of rock mechanics, the frictional behavior of rocks, and the physics of instability in geological materials, the coexistence of slow and fast earthquakes, as well as various types of fault-zone seismic radiation such as tremor, remains enigmatic. Can fault mechanics and friction laws reproduce the full spectrum of observed seismicity? In this week ...[Read More]
