English: The Ianos Mediterranean Hurricane (also known as a Medicane) made landfall in the island of Kefalonia on 18 September 2020, causing flooding, landslides and power cuts, also affecting the islands of Zakynthos and Ithaca and parts of the mainland. The Greek central region of Thessaly has been particularly affected by the storm, with winds of up to 120km/h (75mph) and heavy rainfall that trapped hundreds of people after many streets and houses were flooded. One of the most affected areas is the city of Karditsa, where 3 fatalities were recorded and about 5,000 homes heavily damaged while bridges collapsed and agricultural land turned into mud lakes. In the smaller town of Mouzaki, entire roadways have been flooded, bridges and buildings have collapsed, including the health clinic. Because of these extensive damages, the Copernicus Emergency Management Service has been activated on 19 September (EMSR465) to monitor the flooded areas with delineation maps obtained with high resolution satellite data Service This Sentinel-2 Near InfraRed False Colour image, captured on 20 September 2020, shows two separate views: on the left the town of Mouzaki along the Pamisos river that has caused the collapse of the main bridge and the medical centre. The image on the right shows the city of Karditsa and the surrounding agricultural areas that have been widely flooded. The Copernicus Sentinel-2 mission, composed of two twin satellites (Sentinel-2A and Sentinel-2B) allows to develop applications for flood mapping and damage assessment thanks to its maximum spatial resolution of 10 metres and a maximum revisit time of 5 days.
