evidence: Based on the field surveys by Yalçiner et al. (2017), a moderate tsunami was generated following the earthquake reaching a maximum runup of 1.9 m along a dry stream at Gumbet bay (West of Bodrum, Turkey) and producing an average runup of ~ 0.6 m in the near-field around the city of Bodrum which flooded many nearshore restaurants and damaged boats mainly in the Gumbet bay (Yalçiner et al. 2017). A maximum runup of 1.5 m was observed in Kos Island (Yalçiner et al. 2017). No death was reported due to the tsunami. Details of the tsunami field survey are available in Yalçiner et al. (2017). Tsunami warnings were disseminated by the Tsunami Service Providers (TSPs) within the Intergovernmental Coordination Group, North East Atlantic, Mediterranean and Connected seas Tsunami Warning System (ICG/NEAMTWS). The EMSC disseminated a twitter message advising local people to avoid beaches, despite having no mandate for disseminating such a message and being out of their area of competence.
