Hvad er det største jordskælv californien har haft?
jordskælvet i San Francisco i 1906
List of earthquakes in California
Ifølge seismologen Charles Richter fik jordskælvet i San Francisco i 1906 den amerikanske regering til at erkende problemet. Før det var der ingen instans, der specifikt fokuserede på at undersøge jordskælvsaktivitet. USA's vejrkontor registrerede, når de skete, og flere forskere fra USA's geologiske undersøgelse havde kortvarigt afbrudt deres normale arbejde med at kortlægge mineralressourcerne for at skrive rapporter om New Madrid- og Charleston-begivenhederne, men ingen uddannede geologer arbejdede med problemet, før Coast and Geodetic Survey fik ansvaret efter 1906. Udsigterne blev bedre, da professor Andrew Lawson i 1910 sammen med seismologen Harry Wood, som senere var medvirkende til at få Caltech Seismological Laboratory i gang i 1920'erne, fik statens første overvågningsprogram i gang på University of California, Berkeley.

According to seismologist Charles Richter, the 1906 San Francisco earthquake moved the United States Government into acknowledging the problem. Prior to that, no agency was specifically focused on researching earthquake activity. The United States Weather Bureau did record when they happened and several United States Geological Survey scientists had briefly disengaged from their regular duties of mapping mineral resources to write reports on the New Madrid and Charleston events, but no trained geologists were working on the problem until the Coast and Geodetic Survey was made responsible after 1906. The outlook improved when professor Andrew Lawson brought the state's first monitoring program online at the University of California, Berkeley in 1910 with seismologist Harry Wood, who was later instrumental in getting the Caltech Seismological Laboratory operational in the 1920s.
