When do most earthquakes happen in California and why?

Answer 1

California is located on the edge of the Pacific plate, and is rubbing against another plate, called the Juan de Fuca plate. When the plates collide or rub against eachother, an earthquake occurs.
The earth quakes in california is mostly do to the San andreaus fault,This enormous fault stretches for over 1,000 miles from northern California, through western California, to the East Pacific Rise beneath the waters of the Gulf of California

Answer 2

Many fault lines in the area allow greater/more slippage of tectonic plates than many other places. California is on the Ring of Fire that surrounds the Pacific Ocean, which is the most earthquake prone region. So is Japan.

Answer 3

California is part of the Pacific Ring of Fire where the plate tectonics mean that is where the earth is shifting. The San Andreas Fault zone is one of the most active faults.

Answer 4

this is very interesing to learn about.

Answer 5

because California is on the plate boundarie, Belong to the earthquake zone

Answer 6

I'm guessing but, there are many volcanoes in California because earthquakes are occurring so they are creating volcanoes. Earthquakes occur when plate tectonics touch each other

Answer 7

The earthquakes in California are so bad because San Andreas is on a Stike SLip fault which causes many earthquaks
