In February 2000, the British oceanographic research vessel RRS Discovery, operating in the Atlantic Ocean over the Rockall Trough west of Scotland, encountered the largest waves ever recorded by scientific instruments in the open ocean, with a significant wave height of 29.1 metres (95 ft) and individual waves up to 18.5 metres (61 ft).

The wave came out of the lower part, and looked like the smallest part of the whole thing. The wave did not go up 1,800 feet, the water splashed there. [11] The wave made its way to his boat 2–3 minutes after he saw it and carried the Edrie down to the southern shore and then back near the center of the bay. Ulrich was able to control the ...
The red arrow shows the location of the landslide, and the yellow arrow shows the location of the high point of the wave sweeping over the headland. On July 9, 1958, a giant landslide at the head of Lituya Bay in Alaska, caused by an earthquake, generated a wave that washed out trees to a maximum elevation of 520 metres (1,710 ft) at the ...
The magnitude 9.5 earthquake of 22 May 1960, the largest earthquake ever recorded, generated one of the most destructive tsunamis of the 20th century. The tsunami spread across the Pacific Ocean, with waves measuring up to 25 metres (82 ft) high in places. The first tsunami wave hit Hilo, Hawaii, approximately 15 hours after its origin. The ...
The wave was recorded in 1995 at Unit E of the Draupner platform, a gas pipeline support complex located in the North Sea about 160 km (100 miles) southwest from the southern tip of Norway. [29] [a] At 3 pm on 1 January 1995, the device recorded a rogue wave with a maximum wave height of 25.6 m (84 ft).
Their existence was confirmed in 1958, when a giant landslide in Lituya Bay, Alaska, caused the highest wave ever recorded, which had a height of 524 metres (1,719 ft). [40] The wave did not travel far as it struck land almost immediately. The wave struck three boats—each with two people aboard—anchored in the bay.
The most important clue linking the tsunami in Japan and the earthquake in the Pacific Northwest comes from studies of tree rings (dendrochronology), which show that several "ghost forests" of red cedar trees in Oregon and Washington, killed by lowering of coastal forests into the tidal zone by the earthquake, have outermost growth rings that formed in 1699, the last growing season before the ...
The river is also known, along with Hangzhou Bay, for having what is called by locals as the "Silver Dragon", the world's largest tidal bore, a phenomenon where the leading edge of the incoming tide forms a wave (or waves) that can rise to a height of 9 meters (30 ft) and travels up the river or narrow bay at top speeds of 40 km/h (25 mph; 11 m ...
