The earthquake that killed at least 50 people and injured more than 400 others was the biggest since a magnitude 6.0 quake killed more than 300 people in the town of Mariposa, California, in 1986.
It also broke a record set in December 1988, when a magnitude 7.1 quake killed a total of 932 people.
In 1989, a magnitude 9.0 earthquake killed at more than 1,000 people in San Diego County, California.
In 1990, a quake that killed 539 people and wounded 1,038 killed 1,081 people in Tijuana, Mexico.
And in January 2020, a 7.0-magnitude earthquake killed 1:20 p.m. in San Francisco, killing at least 6 people.
The San Francisco earthquake was the most powerful to hit the state since a 7,700-pound magnitude 5.8 quake struck San Jose, California in August 1989.
