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.

Whether you are a student, educator, or industry professional, you have likely encountered the myriad conventions used for recording geological orientations. For students, this landscape can be perplexing; for professionals, it may lead to the sinking feeling that a crucial undergraduate lecture was missed. Indeed, converting strike and dip measurements between different systems, such as Quadrants ...[Read More]

Faults vs. Fractures — How to Tell Them Apart ?

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]
