What is the difference between epicenter and focus




















Technically, an object becomes the center of attention when a person puts his focus on it. In this view, the center becomes the focus.

The difference between the two, however, is not seen in this light in the field of seismology. It is in the hypocenters or foci that the waves of the earthquake originate. They are described in three different levels: Shallow km. The rule of thumb is that the closer an area is to the epicenter, the stronger the shaking of ground is felt.

The epicenter of an earthquake, on the other hand, is the point in the ground located directly above the focus. It can be accounted for the movement or shaking of the ground that people usually feel during an earthquake.

It happens miles away from the crust layers and may be triggered by tectonic plates or volcanic eruptions. The earthquake starts at the focus and travels up to the epicenter where the ground shaking is felt at its maximum.

Thus, by locating the epicenter of the earthquake, seismologists can determine the origin of the earthquake both above and below the crust. Seismograms are utilized in locating the epicenter through the three seismic stations. The scientists start with recording the time lapse between the detection of the first P-wave and the first S-wave.

Doing so would allow for the recording of a time-distance graph that would point to the proximity of the epicenter from the seismic station.

One can, therefore, say that one difference between the hypocenter and the epicenter is the way they are located. Epicenters are detected through seismographs, while foci are located after the epicenter has been found. Directly above the focus on the Earth's surface is the earthquake epicenter. Physics, What is the difference between the focus and epicenter of an earthquake? While, the epicenter is the point on the Earth's surface above the focus.

Answers: 3 Show answers ; Another question on Physics. Two polarizing sheets have their transmission axes at with respect for each other. Find info on a recent earthquake, greater than magnitude 5. Relationship questions: What does the seismograph measure during an earthquake? The waves emitted from Epicentre is both body and surface waves while waves emitted from Hypocenter is a body wave only.

Now, describe the following… A Where did it occur? Focus and epicenter are two most commonly known terms when it comes to talk about earthquakes because people always take interest in knowing the focus and epicenter of the earthquake.

S-Secondary or Shear waves and 3. Strike-slip dextral, sinistral … Magnitude is determined from measurements on seismographs. Most news stories on earthquakes will list the epicenter of an earthquake and then tell how deep the earthquake was from the epicenter. Keeping this in consideration, what are the focus epicenter and fault? As magnitude increases, the … Speaker is Dr.

L-Long waves or Surface waves. Recorded during a teacher workshop on earthquakes and tectonics. The main difference between an earthquake and an aftershock is how intense the movement of the earth is going to be. Earthquake waves start at the focus and travel outward in all directions.

It is used as a reference point by seismologists to study the spread and effects of earthquakes. Earthquakes are measured using the seismograph. Aftershocks can also be strong … Focus and epicenter are words used in geology; this word causes a lot of confusion amongst students while studying the causes of earthquakes.

The Focus is pretty much where the earthquake starts but some people say it is the center of the earthquake. On the other hand, epicenter is the point which is on the surface of the earth right above … Normally you hear the latitude and longitude of the epicenter when it is reported. Video lecture discusses how scientists determine where an earthquake occurred. How is the focus and hypocenter related? What is the difference between an Earthquake with intensity 7. Focus is the first point of movement along a fault where all earthquake waves originate - it is below the surface.

Simply put, the focus is where the??? The P waves always "wins the race" and the S waves is always the slower "car". The epicenter of an earthquake, on the other hand, is the point in the ground located directly above the focus. Focus-The location where the earthquake begins. The size of the quake.

Difference Between Focus and Epicenter Focus vs Epicenter Technically, an object becomes the center of attention when a person puts his focus on it. Stephanie Danielson says: April 10, at pm. In any direction. The plum pudding model of the atom state that? Rashid— Thanks so much for the great information on focus and epicenter! C Magnitude and Effects?

Concept: Sudden Movements - Earthquakes Focus is the point below the surface of the earth where the quake began while the epicenter is the point dir. Not all ground movements produced during an earthquake are … The difference in speeds of the P and S waves provide a way to locate the epicenter. What is the difference between the epicenter and the focus hypocenter. The epicenter is the geographic spot on the Earth's surface that is directly over the focus.

The epicenter is the point on the surface of the earth directly above the focus. What is the difference between the focus and the epicenter of an earthquake?

Magnitude measures the energy released at the source of the earthquake. What is the difference between the focus of an earthquake and the epicenter of an earthquake? D Tectonic setting? Small earthquakes … Seismic focus. It is the spot where the rock begins to fracture. As tectonic plates move past each other along fault zones , they sometimes get stuck. Pressure builds, and when the plates finally give and slip, energy is released as seismic waves , causing the ground to shake. This is an earthquake.

When energy is released at the focus, seismic waves travel outward from that point in all directions. There are different types of seismic waves, each one traveling at varying speeds and motions. It's these waves that you feel during an earthquake. Focus Hypocenter : The point within the Earth where an earthquake rupture starts. This material is also available as a free iBooks textbook and iTunes U course.
