Why are there no active volcanoes in Southern California?
Volcanic activity is common at both spreading centers and subduction zones. But, because there is no ripping apart or subduction taking place along a transform fault, there isn’t any magma formation to lead to volcanoes. However, the intensity of the faulting easily makes up for this apparent lack of natural disasters.
