Geotechnical Earthquake and GeoHazards Lab

WELCOME!

Geotechnical Earthquake and GeoHazards Lab (GEHL) studies geotechnical earthquake engineering and geohazards to evaluate and predict the impact of earthquakes on infrastructure and urban areas. Our goal is to contribute to the development of more resilient urban systems against natural disasters. GEHL focuses on key topics: dynamic soil-foundation-structure interaction, soil liquefaction during earthquakes, the effects of fault rupture on levees and dams, and site amplification. To address these challenges, we utilize a range of research methods, including centrifuge modeling, numerical simulations, probabilistic approaches, and earthquake case history analysis.
