Significant California Earthquakes

​Below is a table of significant California earthquakes, sorted chronologically (most recent first)​. We've defined "significant" to mean magnitude greater than or equal to 6.5, or that caused loss of life or more than $200,000 in damage. We have not adjusted damage estimates for inflation. This table includes significant earthquakes having epicenters outside of California but within approximately 100 miles of California's border.
