Cracks in Heraklion Walls: Likely a Tectonic Rift, Says Expert

Concern and anxiety have gripped scientists and residents due to the geological phenomenon of cracks appearing in the walls of Heraklion over the past few days. “Most likely, this is a tectonic rift, not caused by an earthquake but by other factors,” emphasized expert Euthymios Lekkas in an interview with ERT on April 28, 2025. He added that large morphological slopes, geological structures, existing fractures in the bedrock, and water infiltration all contribute to the manifestation of the phenomenon. Authorities have asked residents to temporarily evacuate, leaving them in despair. The landslide phenomenon, stretching at least 150 meters, remains under close observation to determine its causes. A team from the National Technical University of Athens (NTUA), led by Euthymios Lekkas, is expected to assist. Six civil engineers from the municipal technical service conducted earlier inspections of buildings and homes, revealing damage to approximately 20 houses, seven of which were deemed potentially unsafe for habitation, prompting temporary evacuation requests. Local authorities closed a children’s playground and are pushing for the area to be declared a state of emergency. Mayor Kalokairinos stated that the initial inspection did not find issues with the nursery or church but recommended keeping the playground closed. Early in the morning, Professor Lekkas held a meeting with local government officials and municipal engineers. Analysis of data collected by these experts is ongoing, with preliminary conclusions about the exact causes expected soon.
