A section of a hillside collapsed into the lake on August 25, 2009, generating a tsunami with an initial wave height of 20 feet (6.1 m) which reached the opposite shore less than 1,000 yards (910 m) away with a height of 12 feet (3.7 m). It struck a campground there and washed a number of people into the lake, but all survived. [137] [174] 2009 ...
At Sado Island, over 350 kilometres (217 mi; 189 nmi) away, a wave height of 2 to 5 metres (6 ft 7 in to 16 ft 5 in) has been estimated based on descriptions of the damage, while oral records suggest a height of 8 metres (26 ft). Wave heights have been estimated at 3 to 4 metres (9.8 to 13.1 ft) even as far away as the Korean Peninsula. [9]
As it approaches land, the wave height of an ordinary tsunami increases dramatically as the sea floor slopes upward and the base of the wave pushes the water column above it upwards. Ordinary tsunamis, even those associated with the most powerful strike-slip earthquakes, typically do not reach heights in excess of 30 m (100 ft). [3] [4]

The shockwave-triggered meteotsunami had a maximum wave height of 0.377 m (1 ft 2.8 in). [130] Minor tsunamis were measured as far away as the Caribbean Sea and Texas, with National Oceanic and Atmospheric Administration reporting a maximum rise of 12 cm (4.7 in) at the Isla de Mona in Puerto Rico at 16:11 UTC.

Along other tsunami-hit locations, most trees remained standing. At Wuhring, a village 5 km (3.1 mi) from Maumere, 3 m (9.8 ft) waves swept through the village and killed 100 people. On Babi Island, the tsunami left human remains hanging on trees; 263 deaths occurred on the island and two villages were badly damaged.
The resulting tsunami reached heights of up to 100 metres (330 ft) on Ambon Island killing over 2,000 individuals. It was the first detailed documentation of a tsunami in Indonesia and the largest ever recorded in the country. [1]
