The ground shook for four to five minutes, roughly twice through “I Want to Hold Your Hand,” the Beatles No. 1 song that year. With the U.S. and the USSR facing off in the Cold War, some thought the Russians had attacked. The quake produced a tsunami that wreaked havoc along the West Coast. Overall damage was estimated at $2.3 billion in 2014 dollars. The quake and resulting tsunamis killed 131 people.
