What new knowledge was gained from the 1906 San Francisco earthquake?

Scientists noted that the intensity of shaking was significantly stronger on soft ground compared to bedrock. Hence, the increased shaking and damage occurring on the soft soils surrounding the San Francisco Bay.

Why does the earth shake when there is an earthquake?

The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond. The seismic waves shake the earth as they move through it, and when the waves reach the earth’s surface, they shake the ground and anything on it, like our houses and us!
