Question	Answer
What property, that is different for P and S waves, provides a method for locating the epicenter of an earthquake?	speed
Movements that follow a major earthquake often generate smaller earthquakes that are called what?	aftershocks

How can P and S waves be used to determine the epicenter of an earthquake?

Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive.

What is the relationship between the difference between P and S waves and distance from the epicenter?

As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

What can the time difference between the P and S wave tell you about an earthquake?

Explanation: Different waves each travel at different speeds and therefore arrive at a seismic station at different times. Difference in arrival times between P and S waves can be used to determine the distance between the station and an earthquake.

Are P waves slower than S waves?

P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

What is a method for locating the epicenter of an earthquake quizlet?

What is the procedure for locating the epicenter of an earthquake? they have to find the difference between the arrival times of the primary and secondary. A circle is drawn around each station. The point where the 3 circles meet is the epicenter.

How do you tell the difference between P and S waves?

Because of their wave movement, P waves travel through any kind of material, whether it is a solid, liquid or gas. On the other hand, S waves only move through solids and are stopped by liquids and gases.

How are S waves and P waves similar?

How are S waves and P waves similar? They shake the ground. They travel through liquids. They arrive at the same time.

What happens to the difference in the arrival time between P wave and S wave as the distance from the earthquake increases?

The different waves each travel at different speeds and therefore arrive at a seismic station at different times. P waves travel the fastest, so they arrive first. With increasing distance from the earthquake the time difference between the arrival of the P waves and the arrival of the S waves increases.

What is the difference between S and P waves?

P waves are recorded earlier than S waves, because they travel at a higher velocity. P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth.

What is the difference of P wave and S wave?

What is the difference between P and S waves?

How are P waves different from pressure waves?

P waves are the fastest seismic waves and can move through solid, liquid or gas. They leave behind a trail of compressions and rarefactions on the medium they move through. P waves are also called Pressure waves for this reason. Certain animals, such as dogs, can feel the P waves much before an earthquake hits the crust (surface waves arrive).

What are the two types of seismic waves?

There are two types of seismic waves : Body waves are the waves that can travel through the layers of the earth. They are the fastest waves and as a result, the first waves that seismographs can record. Body waves can move through all states of matter including rocks and molten lava. Surface waves can only travel on the surface of the earth.

Which is the first wave to arrive at a seismograph?

P waves, or Primary waves, are the first waves to arrive at a seismograph. P waves are the fastest seismic waves and can move through solid, liquid, or gas. They leave behind a trail of compressions and rarefactions on the medium they move through.

Can a dog feel the P wave during an earthquake?

Certain animals, such as dogs, can feel the P waves much before an earthquake hits the crust (surface waves arrive). Humans can only feel the ramifications it has on the crust. S waves, or secondary waves, are the second waves to arrive during an earthquake.
