SKOREA-FESTIVAL-CULTURE-SEA PARTING

People walk out to sea on a pathway exposed by the early morning low tide between the South Korean islands of Jindo and Modo during the 'Jindo Sea Parting festival' on March 22, 2015. The annual phenomenon is understood to be a result of 'tidal harmonics' caused by the relative positions of the Earth, Moon, and the Sun which when 'in phase' create an extreme low tide revealing a causeway between 40 and 60 metres (131 - 196 ft.) wide for around one hour between the islands of Jindo and Modo, on the southern-most tip of the South Korean peninsula. The four-day festival, the dates of which change slightly each year, is a popular attraction for both tourists and locals; many of whom take the opportunity to dig for shell fish and collect seaweed.
