Epicenteret for hovedskælvet lå omkring 3 kilometer uden for kysten. Det bevægede sig langs San Andreas-forkastningen, både mod nord og mod syd i en samlet længde af 477 km.^[3] Rystelserne kunne mærkes fra Oregon til Los Angeles, og inde i landet så langt væk som til det centrale Nevada.

Jordskælvet og de følgende brande huskes som en af de værste naturkatastrofer i De Forenede Staters historie. Dødstallet for jordskælvet og de efterfølgende brande antages at være over 3.000^[4] og repræsenterer det største tab af menneskeliv i Californiens historie.

Det økonomiske tab er blevet sammenlignet med den senere Katrina-orkankatastrofe.^[5]
