Seismic Soundoff

Mojtaba Rajabi discusses his upcoming Pacific South Honorary Lecture, "Present-Day Crustal Stress Across Spatial Scales." The present-day crustal in-situ stress field is of extreme importance for understanding both natural processes (e.g., understanding neotectonics, earthquake, and seismic hazard assessment) and anthropogenic activities (e.g., exploration and production of geothermal energy, groundwater, hydrocarbon, mineral resources, CO2, and hydrogen geo-storage). Analysis of the present-day stresses in numerous basins from across the world reveals that significant and complex variations in the present-day stress orientation are commonly observed at different scales. Mojtaba's lecture aims to investigate the pattern of crustal stress at different spatial scales to better evaluate the causes and consequences of contemporary stress in the earth’s crust. In this conversation with host Andrew Geary, Mojtaba shares why it's necessary to understand the present-day crustal in-situ stress field, the impact of i
