San Andreas Fault USA: Scientists have warned that a very strong earthquake is going to occur in the California region of America. Earthquake tremors are continuously occurring in a part of the San Andreas Fault present here. There is movement beneath the ground. However, this movement is occurring in one part of the fault, the Parkfield section. But scientists fear that this could lead to a bigger earthquake.
Earthquake occurs here every 22 years
Scientists said that the fault is breaking and joining under the ground. Due to which earthquake tremors are being recorded continuously. The Parkfield section is located in central California. An earthquake occurs here every 22 years. Last year in 2004 there was a terrible earthquake here. Although there is no movement across the fault at present, scientists are alert.
Earthquake can hit America any time: Scientist
Scientists recently published a survey in Frontiers in Earth Science. The study says that an earthquake can occur in America at any time, but its center may be different from the center of the 2004 earthquake. Luca Malanini, director of the National Institute of Geophysics and Volcanology, said it is still difficult for scientists to know when an earthquake might strike.
Why does San Andreas become the epicenter of earthquake?
The San Andreas Fault lies between the Pacific and North American tectonic plates. The fault is closed south of Parkfield. That means there is no movement between the two plates. But the motion of the San Andreas Fault is northward. It grows about one and a half inches every year. Parkfield is the area between two plates.
