Final answer:
The largest tsunamis are triggered by earthquakes, landslides, and explosions.
Step-by-step explanation:
The largest tsunami are triggered by earthquakes, landslides, and explosions. Earthquakes are the most common cause of tsunamis, as they can generate powerful undersea disturbances. Landslides or volcanic eruptions that occur underwater can also displace large volumes of water and create tsunamis. Explosions, such as those caused by underwater nuclear tests, can also generate significant tsunami waves.
