Earthquake codes were not taken seriously or even put into buildings designs until after the 1971 San Fernando earthquake.
"A Crack in the Edge of the World: America and the Great California Earthquake of 1906" is a great read about what happened before during and after the great quake of 1906.

He was aware of how often or seldom quakes occurred.
