* Magnitude: The most common way to measure earthquake size is the magnitude, which represents the energy released. The largest earthquake ever recorded was the 1960 Valdivia earthquake in Chile, with a magnitude of 9.5.
* Tsunami Height: However, the "biggest" wave could also be interpreted as the highest tsunami wave. The 1958 Lituya Bay landslide tsunami in Alaska created a wave estimated to have reached a height of over 1,700 feet, but this was a localized event caused by a landslide, not an earthquake.
* Wave Period: Another way to measure wave size is by the wave period, which is the time between crests. Some seismic waves have extremely long periods, lasting for several minutes.
Therefore, there is no single answer to the question of the biggest seismic wave. The answer depends on how you define "biggest".
