What Triggers a Tsunami?
A tsunami is typically produced by a sudden displacement of the seafloor. The most common triggers are:
- Megathrust earthquakes – where one tectonic plate slips beneath another, lifting a large water column.
- Underwater landslides or volcanic eruptions that push water outward.
- Impact events, although these are rare in modern records.
When the ocean floor moves, it creates a series of long‑wavelength waves that can travel across entire ocean basins at speeds exceeding 800 km/h. As these waves approach shallow coastal waters, they increase in height, sometimes reaching several meters in height within minutes.
