In this episode of Geowebinar Insights, we explore how geophysicists and geologists decode the hidden language of the Earth — from radar waves traveling through road foundations to the isotopic clocks ticking inside minerals. Experts discuss the latest advances in ground-penetrating radar, U-Th-He and Ar-Ar dating, and experimental seismic modeling, revealing how these methods help us better understand soil behavior, earthquake preparation, and the age of ore deposits. This conversation bridges fieldwork, laboratory science, and digital interpretation — showing how modern Earth studies illuminate processes invisible to the human eye.
