Describe the effects of the 1964 Alaska earthquake and tsunami.

The 1964 Alaska earthquake, the strongest earthquake ever recorded in North America, struck Alaska’s Prince William Sound, about 74 miles southeast of Anchorage. Most of Alaska’s mainland felt the magnitude 9.2 earthquake, which wobbled Seattle’s Space Needle some 1,200 miles away. The earthquake was so powerful it registered in all U.S. states except Connecticut, Rhode Island and Delaware. The quake also led to significant scientific breakthroughs in subduction earthquakes and how to minimize their destruction.
