[email protected] Abstract: On 30 October 2020, an Mw = 7.0 earthquake struck the eastern Aegean Sea. It triggered earthquake environmental effects (EEEs) on Samos Island detected by field surveys, relevant question- Citation: Mavroulis, S.; Triantafyllou, naires, and Interferometric Synthetic Aperture Radar (InSAR) analysis. The primary EEEs detected I.; Karavias, A.; Gogou, M.; in the field comprise coseismic uplift imprinted on rocky coasts and port facilities around Samos and Katsetsiadou, K.-N.; Lekkas, E.; coseismic surface ruptures in northern Samos. The secondary EEEs were mainly observed in northern Papadopoulos, G.A.; Parcharidis, I. Samos and include slope failures, liquefaction, hydrological anomalies, and ground cracks. With the Primary and Secondary contribution of the InSAR, subsidence was detected and slope movements were also identified in Environmental Effects Triggered by inaccessible areas.
