San Francisco

After Iceland I decided to go to a Transform Boundary. The San Andreas fault is a good example of one. A Transform Boundary is where two plates are shifting against each other. One is sliding up and one is sliding down. The plates have been moving for around 10,000,000. They move around 5 centimeters a year. But the earth is still moving below us which is kind of scary.

Earth quakes are happening all of the time here. Most of them are just to small to feel. These plates are responsible for the massive earthquakes in 1906 and 1989 in San Francisco.

The fault line enters the us above Los Angels and stops after Baja California. Scientists predict that Los Angeles will be above San Francisco in around 100,000,000 years. That is a long time but I think that is crazy that that much land can move that much!
