Which term describes a tsunami caused by displacement of the earth along a fault?

• A. Tsunami
• B. Seaquake Wave
• C. Seismic Sea Wave
• D. Ocean Surge

Answer: (C)

When the seafloor moves suddenly along a fault, it displaces a huge amount of seawater and launches waves that travel across the ocean. The term used for a tsunami caused by this seismic displacement is a seismic sea wave, because it directly ties the phenomenon to the earthquake origin. This is more precise than simply calling it a tsunami, which names the wave but not its cause, and it avoids nonstandard terms like “seaquake wave” or “ocean surge,” which don’t correctly describe an earthquake-generated ocean wave.
