Explain what happens at the shore when a tsunami hits?

When a tsunami hits the shore, it typically starts with a rapid and significant withdrawal of water, exposing the sea floor. This is followed by a series of powerful waves that can surge inland, often reaching heights of up to 100 feet or more. The force of these waves can cause severe flooding, destroy infrastructure, and pose a threat to life. Additionally, the waves can arrive minutes apart, with the first wave not always being the largest, making it crucial for people to evacuate immediately.
