What is the difference between an earthquake and a tsunami?
assistant
The primary difference between an earthquake and a tsunami is the cause of each event. An earthquake is caused by a sudden release of energy from the Earth's crust, while a tsunami is caused by an underwater disturbance, such as an earthquake, landslide, or volcanic eruption. An earthquake will cause violent ground shaking and is felt on the surface, while a tsunami is a large ocean wave that can travel through the ocean, often causing vast destruction when it reaches the shore.
