The tectonic plates shift causing them to collide and shake the ground.
Southern California did not have any significant earthquakes in 1967. There was an earthquake in 1968 and 3 earthquakes in 1969 that did significant damage to southern California.
California
Southern California experiences thousands of earthquakes every year, but most are very small and go unnoticed. On average, Southern California typically experiences several hundred earthquakes each year that are large enough to be felt by people.
Earthquakes.
the titonic plates shift and move under the ocean which cause earthquakes and tsunamies
No. Earthquakes can cause landslides, but those are basically just scratching the surface. While will happen is that southern California will slowly move northward over the course of millions of years.
Well earthquakes are unpredictable and cause because of shifting in plates places like California and Chili have lots of earthquakes because there on faltes.
A La Nina climate pattern is associated with drier than normal conditions in Southern California.
California and southern Alaska both experience significant earthquake risks, but Alaska generally has a higher frequency and intensity of seismic activity. The Aleutian Islands in southern Alaska are located along the Pacific Ring of Fire, making them prone to large subduction zone earthquakes. While California has a well-known fault system, including the San Andreas Fault, the overall risk of experiencing a major earthquake is typically higher in southern Alaska due to its tectonic setting. However, California's higher population density means that the impact of earthquakes can be more pronounced there.
Tectonic underground plates going over each other
Plate tectonics can create mountains. Plate Tectonics can also cause earthquakes in California.
The main cause of earthquakes is when there is a sudden movement of various plate boundaries or when plates scrape against each other. Some earthquakes are also caused from old plate boundaries or faults. Many earthquakes happen at faults, such as the San Andreas Fault in California.
