Q

What should you expect when you encounter a tsunami in the open ocean?

🔍 Key Concepts

• Tsunami behavior in deep (open-ocean) water vs. shallow coastal water • Wave height vs. wavelength and speed for tsunamis • Difference between local weather/sea state and long-period tsunami waves

💭 Think About

• Ask yourself: in deep water, does a tsunami usually appear as a huge breaking wave, or as something more subtle? • Consider what actually creates violent, confused seas or gale‑force winds—are those caused directly by a tsunami or by weather systems? • Think about how shipboard observers at sea have historically described tsunamis before they reach the coast—do they report dramatic waves or minimal visual change?

✅ Before You Answer

• Verify how tsunami wave height in deep water compares to normal wind waves. • Check how tsunami wavelength and period affect how noticeable the wave is to someone on a vessel in the open ocean. • Confirm whether wind strength and direction are directly affected by tsunamis or are independent weather phenomena.
