1. What Determines How Far Inland a Tsunami Can Travel?

The distance a 300-foot tsunami could travel inland varies greatly, influenced by several key factors. It’s not solely about the height of the wave, but also the land elevation, the tsunami’s energy, and the coastal geography.

• Land Elevation: A primary factor is the elevation of the land. A tsunami will naturally travel further inland across flat, low-lying coastal plains than it will against steep cliffs or rising terrain.
• Tsunami Energy: The energy a tsunami carries dictates how far it can push inland. This energy is affected by the initial event that caused the tsunami, such as an earthquake or landslide, and how far the wave has traveled.
• Coastal Geography: The shape of the coastline, including bays, rivers, and inlets, can channel and amplify a tsunami’s surge, allowing it to penetrate further inland in certain areas.

According to research from the National Oceanic and Atmospheric Administration (NOAA), coastal inundation depends heavily on local bathymetry and topography.

2. How Does Tsunami Speed Affect Inland Travel Distance?

Tsunami speed plays a vital role in determining how far inland it can travel. While traveling across deep ocean waters, a tsunami can reach speeds of hundreds of miles per hour but with a relatively small wave height.

• Deep Ocean Speed: In the deep ocean, the immense depth allows a tsunami to travel at tremendous speeds, often unnoticed by ships because of its low amplitude.
• Shallowing Waters: As the tsunami approaches the shore and the water becomes shallower, its speed decreases significantly. This decrease in speed causes the wave’s energy to convert into height, creating the towering wave seen at the coastline.
• Energy Release: The distance a tsunami travels inland is directly related to the energy it retains upon reaching the shore. A high-energy tsunami will surge further inland, overcoming obstacles and inundating low-lying areas.
