Results from a multidisciplinary investigation at the Lastros-Sfaka Graben located in eastern Crete are presented. 1.3 km of the Lastros fault was scanned with t-LiDAR and we identified areas with minor external influences (anthropogenic, depositional or erosional) to extract throw rates. Preliminary postglacial throw rates are 0.67 ± 0.15 mm/yr., which is significantly less than stated in the literature. Cemented colluvium is located on the Lastros fault, forming hanging-wall talus lobes and sheets of varying thickness attached to the fault plane. Stable isotope analysis on the cement ndicates that it has a meteoric origin and precipitated from water at temperatures between 5 and 8°C. Field mapping and GPR shows that cemented colluvium, is also present within the hanging-wall subsurface. Trenching (road cut) investigations on the Sfaka fault identified fill material most likely deposited soon after the last palaeoearthquakes that occurred on the fault; 14C dating is currently being carried out to date this fill material.
