Smaller (M w 4.2) earthquakes in Japan can trigger tsunamis (called local and regional tsunamis) that can devastate stretches of coastline, but can do so in only a few minutes at a time. Landslides The Tauredunum event was a large tsunami on Lake Geneva in 563 CE, caused by sedimentary deposits destabilised by a landslide.
Some animals have been thought to perceive the infrasonic waves going through the earth, caused by natural disasters, and to use these as an early warning. An example of this is the 2004 Indian Ocean earthquake and tsunami. Animals were reported to have fled the area hours before the actual tsunami hit the shores of Asia.

A teletsunami (also called an ocean-wide tsunami, distant tsunami, distant-source tsunami, far-field tsunami, or trans-ocean tsunami) is a tsunami that originates from a distant source, defined as more than 1,000 km (620 mi) away or three hours' travel from the area of interest, [1] [2] sometimes travelling across an ocean.

The upper limit for humans is considered to be 18 kHz. The upper and lower limits of elephant hearing are the lowest measured for any animals aside from the pigeon. [10] By contrast, the average best frequency for animal hearing is 9.8 kHz, the average upper limit is 55 kHz. [10]
The Lituya Bay megatsunami caused damage at higher elevations than any other tsunami, being powerful enough to push water up the tree covered slopes of the fjord with enough force to clear trees to a reported height of 524 m (1,719 ft). [9] A 1:675 recreation of the tsunami found the wave crest was 150 m (490 ft) tall. [14]
