Tectonics and Structural Geology
Portrait of Dr. Hardy Nkodia, a Congolese structural geologist and researcher specializing in tectonics, paleostress analysis, and earthquake geology.

Nkodia Hardy

I’m Hardy Nkodia, PhD in Tectonics & Structural Geology from the Republic of Congo. I work as a Research Assistant and Lecturer in Marien Ngouabi University in Congo, and I’m beginning a postdoc at the Active Fault & Earthquake Hazard Mitigation Research Institute, Pukyong National University (South Korea). I study structural geology, paleostress, paleoseismology, and mining, with a passion for using GIS to make geodata open to all. I love turning complex ideas into clear explanations and mentoring students.

Faults vs. Fractures — How to Tell Them Apart ?

A futuristic Black geologist wearing AR glasses stands in a glowing cave surrounded by four holographic screens labeled Geological Aspect, Geometry, Topology, and Kinematics & Mechanism, each displaying geological diagrams and fracture models, symbolizing modern geoscience visualization.

Faults and fractures can sometimes be confusing, especially for students taking their first geology courses. When they go hiking in the mountains and see a crack in the rock, they often wonder — is this a fracture or a fault? Even scientists sometimes mix the two terms, so it’s good to understand the difference. Since faults and fractures are important in many fields such as tunnel engineering, hy ...[Read More]
