Description
Southern coastline of Jogashima Island (Kanagawa Prefecture, Japan) with a view of the Umanose Arch in the far distance.
Small boats used to pass through the Umanose Arch during high-tide until the 1923 Great Kanto Earthquake lifted the seabed up by about 1.4 meters (4.6 ft) bringing the entire arch above sea level and creating a newly exposed rocky coastline.
