Even though the magnitude of the 1906 earthquake was large (M 7.8), it generated a tsunami wave only approximately 10 cm in height. The primary tsunami threat along the central California coast is from distant tsunamis generated by earthquakes along subduction zones, such as the 1964 Great Alaska earthquake.
Similarly, you may ask, what caused the 1906 San Francisco earthquake?
At 5:12 a.m. on April 18, 1906, the people of San Francisco were awakened by an earthquake that would devastate the city. The main temblor, having a 7.7–7.9 magnitude, lasted about one minute and was the result of the rupturing of the northernmost 296 miles of the 800-mile San Andreas fault.
Secondly, which earthquakes cause tsunamis? Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world's tsunamis occur in the Pacific along its Ring of Fire subduction zones.

Can San Andreas really happen?
No. Magnitude 9 earthquakes only occur on subduction zones. As stated above, there hasn't been an active subduction zone under San Francisco or Los Angeles for millions of years. However, earthquake intensity along the modern-day San Andreas fault maxes out at approximately 8.3 (The Hollywood Reporter).Did the Golden Gate Bridge collapse in 1989?
When the conversation turns to earthquakes, Astaneh becomes more serious.
