how tall is a dangerous tsunami
Some tsunamis will have a surge in front of them as they approach land. These surges can be very damaging and dangerous. Notice a landslide that falls or slides into the ocean, a large lake, or a river. EVACUATE IMMEDIATELY! if you notice any of these signs or hear a tsunami warning. Tsunami evacuation. Tsunami waves can be 30â100 feet tall or more. If you cannot evacuate to higher ground, go as far inland as possible. If there is a large earthquake, roads and bridges may be damaged.
