This multitemporal colour composite SAR image centres over the Strait of Messina, separating Calabria in southern Italy from Sicily. The image shows the main towns along the Strait: Messina in Sicily and Reggio-Calabria in Calabria. The varied colours in the sea reflect currents, whirlpools, and wind-induced surface roughness visible at the time of acquisition.
