Foulness Island level, which was above the danger level for this part of the Essex coast. This level in itself was not a danger to the island, as the sea walls had been raised and strengthened between 1951 and 1952 by the War Office, and were above mean sea level. However, the high water was accompanied by strong winds, creating large waves, which broke over the top of the defences, washing away the earth banks on the inland side of the walls. Two sections of the wall breached, from Rugwood Head to Asplin's Head on the eastern side of the island, and
Bouvet Island Kapp Fie. After rounding Kapp Fie, the coast along the south side is known as Vogtkysten. The westernmost part of it is the long shore of Sjøelefantstranda. Off Catoodden, on the south-western corner, lies Larsøya, the only island of any size off Bouvetøya. The western coast from Catoodden north to Nyrøysa, is known as Esmarchkysten. Midway up the coast lies Norvegiaodden (Kapp Norvegia) and off it the skerries of Bennskjæra. 93 percent of the island is covered by glaciers, giving it a domed shape. The summit region of the island is Wilhelmplatået, slightly to the west of the island's center.
