Twenty-two years almost to the day after the terrifying Loma Prieta earthquake, two quakes jolted the San Francisco Bay area again, the first a magnitude 4.0 and the second a 3.9, both hitting not far from the University of California at Berkeley campus.

Although there were no injuries or damage from Thursday’s quakes, they were a potent reminder for Californians of the fault lines they live on, especially for those who lived through the Loma Prieta quake.

The Oakland A’s and San Francisco Giants were just warming for the the third game of the World Series when Loma Prieta hit, caused by a slip line the San Andreas fault.

Lasting just over 10 seconds, the quake clocked in at an incredible 6.9 on the Richter scale and left 63 people dead, thousands injured and some $10 billion in damage.
