#41: What can sinkholes tell us about our planet’s future?
from Arqus Knowledge Pills · host Arqus European University Alliance
What causes the Earth to suddenly collapse beneath our feet? Can geophysics help us predict—and perhaps even prevent—natural disasters? These are just some of the fascinating questions explored in the latest episode of the Arqus Knowledge Pills podcast with special guest Professor Djamil Al-Halbouni, expert in Applied Geophysics and Remote Sensing at Leipzig University.In this episode, Professor Al-Halbouni guides us through the invisible forces shaping our landscapes—from sinkholes in the Dead Sea region to erosion in Bronze Age archaeological sites. Drawing on his international research experience and innovative use of numerical simulation, remote sensing, and fieldwork, he explains how water-related processes such as subsidence and collapse can reveal urgent insights into both our past and future environments.The conversation also highlights his recent Arqus course in the Granada Geopark, where students explored how geophysical methods connect natural history with cultural heritage. Geoparks offer unique learning opportunities that bridge science, sustainability, and storytelling.Professor Al-Halbouni also discusses the social impact of natural hazards on vulnerable communities, especially those living along the receding shores of the Dead Sea. He reflects on the potential of new technologies, including AI and satellite data, to support early-warning systems and more resilient planning strategies.Learn more about Djamil Al-Halbouni:Djamil Al-Halbouni is a Junior Professor of Applied Near-Surface Geophysics and Remote Sensing at Leipzig University. His research focuses on geophysical modelling and monitoring of near-surface hazards, with particular expertise in sinkhole formation and subsidence processes. He played a leading role in the international project DESERVE, investigating sinkholes and landslides around the Dead Sea, one of the world’s most dynamic and vulnerable regions to such geohazards.Al-Halbouni holds a diploma in Geophysics from the University of Göttingen and completed his PhD at the University of Potsdam and the German Research Centre for Geosciences (GFZ), including a research stay at the University of Adelaide and CSIRO in Australia. His work also spans groundwater dynamics in karst aquifers, hydromechanical modelling of canyon systems, and the stability of salt caverns in Brazil and Germany. Before joining Leipzig, he held postdoctoral positions at GFZ, GEOMAR, and the University of Malta.
