The San Andreas fault
San Andreas
A fault is where to tectonic plates meet but a fault zone is the area around a fault.
Indiana and a number of neighboring states experience earthquakes, which in modern times have been small and nondestructive. It is unusual to have a major fault in the middle of a continent, but that does exist in this region.Southern Indiana is close to the New Madrid fault. New Madrid, now in Missouri, was the location of the New Madrid earthquakes, 1811-1812, which historical accounts suggest were the largest ever recorded in the eastern US and possibly the largest in North America. The fault is now well mapped and the active area includes several neighboring states and much of Indiana.

Scientists also look for areas where earthquakes have not occurred along an otherwise active fault.

Yes, San Gabriel, California has experienced earthquakes. It is located near the San Andreas Fault, which is a major tectonic boundary that is known for its seismic activity. The area has a history of earthquakes, including the notable 1987 Whittier Narrows earthquake.
Seismic gaps.
Earthquakes are caused by the shifting of the Earth's plates usually at transform boundaries. California is a major earthquake area in NA because of the San Andreas fault line.
Near any fault lines but earthquakes tend to happen more on the west coast. For example, in California there is a big fault line called the San Andres fault and it took down San Francisco in the early 1900's.
Fault lines exist where one tectonic plate meets another. For example the San Andreas Fault in California is the boundary between the North American plate (on the east of the fault line) and the Pacific plate (on the west of the fault line)
Because it is close to the San Andreas fault
the tension built up make earthquakes around this area
