Where is the focus of an earthquake?
The focus (more correctly termed the hypocenter) of an earthquake is the point in the earth where the earthquake rupture or fault movement actually occurred. The point on the surface directly above the hypocenter is known as the epicenter.
How are faults and epicenters related?
The violent shaking and destruction associated with earthquakes are the result of rupture and slippage along fractures in Earth's crust called faults. Larger quakes result from the rupture of larger fault segments. The origin of an earthquake occurs at depths between 5 and 700 kilometers, at the focus(foci = a point). The point at the surface directly above the focus is called the epicenter.
What was the epicenter of 1906 San Francisco Earthquake?
The epicenter of the 1906 San Francisco Earthquake was near San Francisco in the Pacific Ocean, close to the San Andreas Fault. The earthquake, which occurred on April 18, 1906, was a major event with a magnitude of about 7.9.
Why can earthquakes cause a destruction far from the epicenter?
Because earthquakes rupture sections of a fault, sometimes for hundreds of miles. So it is possible for there to be just as much destruction anywhere along the fault as there is at the epicenter. (the epicenter being at the beginning of the rupture)
The location on the surface of the earth immediately above the origin of a fault is called?
The location on the surface of the earth immediately above the origin of a fault is called the "epicenter."
What does the buckling of rocks under great force produce?
a fault
Is the epicentre always on a fault line?
No, the epicenter is not always on a fault line. The epicenter is the point on the Earth's surface directly above where an earthquake originates, which is the focus or hypocenter. Earthquake epicenters can occur both on and off fault lines.
What is the exact location in a fault where energy is released during an earthquake?
epicenter
The location on the surface of the earth immediately above the origin of a fault is called .?
epicenter.
Why is Florida a target for earthquakes?
it is a target for earthquakes because it is on a fault line and the epicenter is right above that
Is the epicenter of an earthquake the point of rupture along the fault?
the epicentre is the point directly above the focus.
Where is the focus of an earthquake?
The focus (more correctly termed the hypocenter) of an earthquake is the point in the earth where the earthquake rupture or fault movement actually occurred. The point on the surface directly above the hypocenter is known as the epicenter.
Which type of force produces strike-slip fault?
The force that produces a strike slip fault is a shearing force.
What was the epicenter of the 1906 San Francisco?
The epicenter was just to the north west of San Francisco, however the earthquake ruptured the whole northern section of the San Andreas fault for a distance of 296 miles.
How are faults and epicenters related?
The violent shaking and destruction associated with earthquakes are the result of rupture and slippage along fractures in Earth's crust called faults. Larger quakes result from the rupture of larger fault segments. The origin of an earthquake occurs at depths between 5 and 700 kilometers, at the focus(foci = a point). The point at the surface directly above the focus is called the epicenter.
What is the difference between epicenter and a earthquake?
An earthquake is the sudden shaking of the grounddue to the energy released by sudden movement along a fault line in the earth's crust.The epicenter is a point on the earth's surface directly above the focus of the earthquake.The focus is the point underground where the fault line starts rupturing.
What was the epicenter of 1906 San Francisco Earthquake?
The epicenter of the 1906 San Francisco Earthquake was near San Francisco in the Pacific Ocean, close to the San Andreas Fault. The earthquake, which occurred on April 18, 1906, was a major event with a magnitude of about 7.9.
