evidence: Serious tsunami hits Greece and Turkey after 7.0 earthquake [...] Within 8-11 minutes after the detection of the earthquake, tsunami bulletins were issued to national focal points by the Tsunami Service Providers (TSPs) accredited by UNESCO’s IOC Intergovernmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North-eastern Atlantic, the Mediterranean and connected seas (ICG/NEAMTWS)*. Greece and Turkey were put on "Tsunami Watch" (highest level of alert), while other countries either on "Tsunami Advisory" and/or "Tsunami Information" levels. [...] On 12 June 2017 and 20 July 2017, two small-scale tsunami events occurred in the Aegean Sea (Mw 6.3 and Mw 6.9, respectively), the former impacting the island of Lesvos (Greece) and the latter impacting the island of Kos (Greece) and the Bodrum region in Turkey, within a few minutes after the earthquakes. As no timely alert reached the population, the community remained in the hazard area, exposed to a high risk.
