Is Kaikoura on a fault line?
The magnitude 7.8 Kaikoura earthquake in 2016 was a complex event, involving movement on at least seven faults – The Humps faults and the Hundalee, Hope, Jordan Thrust, Papatea, Kekerengu and Needles faults.
Where are tsunamis most common in Japan?
Which areas of Japan are most prone to tsunami? Experts suggest anywhere is prone to a tsunami, but the Pacific coast is seen at higher risk because major earthquakes are expected along a path stretching from Kochi to Shizuoka prefectures.
Is a tsunami deep or shallow wave?
Tsunamis are characterized as shallow-water waves. Shallow-water waves are different from wind-generated waves, the waves many of us have observed at the beach.

Why does the sea recede before a tsunami?
Why does the water level drop before the tsunami hits? Because it is like a tide, the tide goes out before it comes in. As the tsunami approaches water is drawn back from the beach to effectively help feed the wave. In a tide the wave is so long that this happens slowly, over a few hours.
Do tsunami waves break?
Tsunami waves are unlike typical ocean waves generated by wind and storms, and most tsunamis do not “break” like the curling, wind-generated waves popular with surfers. When tsunamis approach shore, they behave like a very fast moving tide that extends much farther inland than normal water.
Can a tsunami be seen from the air?
For the same reason of low amplitude and very long periods in the deep ocean, tsunami waves cannot be seen nor detected from the air. From the sky, tsunami waves cannot be distinguished from ordinary ocean waves.
