What is the point inside the earth where an earthquake occurs?
The location below the earth's surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows.
What is a epicenter of an earthquake?
The epicenter is the point on the earth's surface vertically above the hypocenter (or focus), point in the crust where a seismic rupture begins.
Where is the focus located?
Epicenter is the location on the surface of the Earth directly above where the earthquake starts. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts.
Where is the point at which the first movement occurs during an earthquake?
earthquakes hypocenter The point on a fault at which the first movement or break occurs during an earthquake is called the earthquakes hypocenter (focus) (figure 1).
What is focus and epicenter?
The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
Where are earthquake epicenters located?
The epicenter is located on the surface directly above the focus (hypocenter), which is located on the fault at depth. The latitude and longitude will be the same for the epicenter and hypocenter of the same event.
What is focus point in geography?
The point inside the crust where the pressure is released is called the focus . The point on the Earth's surface above the focus is called the epicentre . Earthquake energy is released in seismic waves. These waves spread out from the focus.
What is meant by focal depth?
The focal depth refers to the depth of an earthquake hypocenter.
What is the difference between focus and epicenter?
This is an earthquake. The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.

What do you mean by Epic Centre?
The meaning of epi- in epicenter is "over", so the epicenter of an earthquake lies over the center or "focus" of the quake. Epicenter can also refer to the centers of things that may seem in their own way as powerful—though not as destructive—as earthquakes.
What is meant by epicenter Brainly?
The epicenter, is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates.
What is called focal point?
focal point. noun. Also called: principal focus, focus the point on the axis of a lens or mirror to which parallel rays of light converge or from which they appear to diverge after refraction or reflection. a central point of attention or interest.
What is focal point and examples?
The definition of a focal point is something or someone that captures the bulk of the attention, either intentionally or by chance. An example of a focal point is a bright red wall in your living room designed to draw the eye to it. noun. 2. (optics) A focus; a point at which rays of light or other radiation converge.
What is focal depth and epicenter of an earthquake?
Terminology. The point on the fault where slip starts is the Focus or Hypocenter, and the point vertically above this on the surface of the Earth is the Epicenter (Figure 1). The depth of focus from the epicenter, called as Focal Depth, is an important parameter in determining the damaging potential of an earthquake.
What is earthquake focus?
The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus. See also epicenter.
How are faults foci and epicenters related?
How are faults, foci, and epicenters related? A fault is a large fracture along which there is movement. When movement occurs, the zone within Earth where rock displacement occurs is termed the focus. The point on Earth's surface directly above the focus of an earthquake is called the epicenter.
What is the difference between focus and epicentre prior knowledge present knowledge gained knowledge?
The point where the energy is released is called the focus of an earthquake or hypocentre. The point on the surface of the earth which is vertically above the focus is called the epicentre. It is the first place to experience the waves.

What happens at focal point?
As mentioned above, light rays incident towards either face of the lens and traveling parallel to the principal axis will either converge or diverge. If the light rays converge (as in a converging lens), then they will converge to a point. This point is known as the focal point of the converging lens.
