Urban resilience and its malleable definition have rendered its operationalisation a challenging endeavour for
contemporary cities trying to address their organisational problems and confront uncertainty in
a holistic manner. This research investigates the implementation challenges Resilient
Strategies are facing due to lacking attention paid to urban geological risk. While urban geological risk is conceptualised as
the combination of urban geohazards, geological vulnerability and exposure of the built environment, this work
focuses on the case study of Thessaloniki, Greece, a city that joined the 100 Resilient Cities initiative
in 2014 and published its “Resilience Strategy 2030” in 2017. After a review of Strategy and a combination of historical
records of natural hazards with data from interviews with city officials, earthquakes and surface flooding were selected as the most relevant geohazards to be confronted for the city of Thessaloniki. Initially, geological vulnerability to
earthquakes is examined in conjunction with exposure of the built environment, as an outcome of ageing building
stock, high building densities and the urban configuration, in Acheiropoietos neighbourhood,
within the historic centre of the city. Then, the geological risk to surface flooding in one of the municipalities of the metropolitan area of Thessaloniki, namely Perea in Thermaikos Municipality, is explored. Focusing on flash floods and this part demonstrates how limited considerations of local geomorphology as well as semi-regulated urban expansion and its limited
connection with emergency planning increase exposure of the built environment to surface flooding. Lastly, some major implementation challenges for Thessaloniki's Resilience Strategy are presented.
