Which statement best describes the global significance of the 1964 Alaska earthquake?

• A. It Is Among The Least Powerful
• B. It Is Among The Most Powerful
• C. It Is The Most Powerful
• D. It Has No Significance

Answer: (B)

The main idea here is understanding how a quake’s size and its effects translate into global significance. The 1964 Alaska earthquake was colossal, measuring about magnitude 9.2. That places it among the strongest earthquakes ever recorded; only the 1960 Chile event was larger, so this Alaska event ranks right at the top of global records. Its consequences weren’t confined to Alaska—tsunamis traveled across the Pacific, and the shaking and damage influenced seismic science, tsunami warning systems, and building codes around the world. Because it combines an extreme size with far‑reaching impacts, describing it as among the most powerful worldwide accurately captures its global significance without overstating it as the absolute largest.
