ジャルート環礁
Eyewitness accounts verify ridges of this kind are formed by severe tropical cyclones and two clear examples cited are the long, wide, high coral shingle ridge deposited on Funafuti Atoll (Central South Pacific) by Cyclone Bebe in October 1972, and the large coral shingle ridge deposited on Jaluit Atoll (Marshall Islands) by Typhoon Ophelia in January 1958. In tropical northeast Australia, an intense tropical cyclone hit in March 1918 (crossing over the town of Innisfail), at which time there were eyewitness accounts of a to high ridge of pumice being deposited by that cyclone's surge as it crossed the coast.).
