Today, April 18, 2026, is the 120th anniversary of an event that is considered one of the deadliest natural disasters to strike California—the 1906 San Francisco Earthquake.

Map of destroyed section San Francisco, 1906
This earthquake began on a Wednesday morning at 5:12a.m. local time when many were still in
bed and others were starting to prepare for their workday. The main shaking
lasted forty to sixty seconds—long for an earthquake in this state. Between the
destruction to buildings caused by the quake itself and the fires that followed,
over eighty percent of San Francisco was destroyed, and 200,000 people were
left homeless. 3,000 people perished.
California is known for its earthquakes. I have lived through several, including one in February of 1971 when I lived in Santa Monica, one in November of 1988 when I was visiting family in Orange County (my infamous “rocking sideways toilet” tale), and the well-known October 1989 Loma Prieta earthquake which interrupted the World Series in Oakland and collapsed two major sections of San Francisco Bay Area freeway. I felt it where I lived over one-hundred miles to the southeast while sitting in my car at an intersection waiting for the light to change. The quake was strong enough that I suffered motion sickness before it ended. That one was 6.9 on the Richter Scale at its epicenter in the Santa Cruz Mountains just south of the San Francisco Bay area.
The Richter Scale did not exist until 1935. However, from the geological studies performed at the time, it is estimated that the 1906 San Francisco Earthquake was about 7.9 on the Richter Scale, with a rupture about 296 miles in length along the San Andreas fault. The epicenter was just south of San Francisco.
Many affected residents who were able, dressed as quickly as they could in their best. However, because they feared the aftershocks might cause additional damage and trap them inside their buildings, few gathered many of their belongings to take with them as they fled their homes.

If you are still with me, my upcoming release is dated between 1903 and 1908. My hero grew up in turn-of-the-century San Francisco, and returns to check on family once he learns of the earthquake.
