QuestionAnswerWhat type of seismic wave causes the greatest destruction to buildings?surface wavesWhat are three major differences between P and S waves?speed, what type of material they can move through, direction of the movement
Which seismic wave is the first to reach a seismic station?
The P wave is designated the primary preliminary wave because it is the first to arrive at a seismic station after an earthquake. It travels at a speed usually less than 6 kilometers per second in the Earth’s crust and jumps to 13 kilometers per second through the core.
Which type of seismic wave tends to cause the greatest destruction to buildings quizlet?
Which type of seismic wave tends to cause the greatest destruction to buildings? Surface waves exhibit the greatest amplitudes and retain their amplitude longer, so they tend to cause greater ground shaking and therefore greater property damage than P or S waves..Which seismic waves will have the greatest amplitude on a seismogram?
The primary, or P, waves travel most quickly and are the first to be registered by the seismograph. Secondary, or S, waves travel more slowly. As S waves have a greater amplitude than P waves the two groups are easily distinguishable on the seismogram.
How are faults Hypocenters and epicenters related?
How are faults, hypocenters, and epicenters related? The hypocenter is the exact point underground along a fault where the slippage of the two blocks of rock occurs. The epicenter is the point on Earth’s surface that is directly above the hypocenter. … The epicenter is located where the three circles intersect.
Where do the largest and most powerful earthquakes occur quizlet?
Convergent Plate Boundaries: Subduction zone: Where an oceanic plate collides with another plate, one plunges into the interior and the other overrides. The largest earthquakes ever recorded have occurred at subduction zones.
What is AP wave and S wave?
P waves can travel through solids, liquids, and even gases. S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side.What kind of seismic wave arrive last at seismic station?
The different S waves arrive after the P waves. The slowest (and latest to arrive on seismograms) are surface waves, such as the L wave. L waves are named for the Cambridge mathematician A.E.H. Love who first described them.
Which is the first seismic wave to arrive at the seismic station Brainly?An earthquake produces P waves, or compressional waves, that travel faster and reach the seismograph first, and S waves, or shear waves, that are slower. Earthquakes also have surface waves that are similar to surface waves on water. Marketing cookies are used to track visitors across websites. 40,000 miles.
Article first time published onWhich seismic waves will have the greatest amplitude on a seismogram and will arrive last to a seismic station?
S-waves are more dangerous than P-waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves.
Which of the following shows the highest amplitude on a typical seismogram?
B) surface waves is the answer.
Which of the following has the greatest seismic activity?
The world’s greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet’s largest earthquakes occur. It has earned the nickname “Ring of Fire”. Why do so many earthquakes originate in this region?
How are P waves and S waves different?
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. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
Which type of plate boundary is associated with Earth's most destructive earthquakes?
At convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful. In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
How does the lithosphere differ from the asthenosphere choose all that apply?
A single supercontinent consisting of all Earth’s landmasses once existed. How does the lithosphere differ from the asthenosphere? … The lithosphere tends to break, while the asthenosphere tends to flow. The lithosphere overlies the asthenosphere.
Which kind of seismic wave travels the most slowly?
Surface waves are the slowest of all seismic waves, traveling at 2.5 km (1.5 miles) per second.
What type of seismic wave is S wave?
Secondary waves (S-waves) are shear waves that are transverse in nature. Following an earthquake event, S-waves arrive at seismograph stations after the faster-moving P-waves and displace the ground perpendicular to the direction of propagation.
What are the 3 types of seismic wave?
There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.
What is AP wave?
A P wave, or compressional wave, is a seismic body wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving.
Which category of surface waves cause the most damage to structures?
Love waves have a particle motion, which, like the S-wave, is transverse to the direction of propagation but with no vertical motion. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that’s why Love waves cause the most damage to structures.
What are 4 types of seismic waves?
- P-wave Motion. P-wave:the primary body wave; the first seismic wave detected by seismographs; able to move through both liquid and solid rock. …
- S-wave Motion. …
- Rayleigh-wave Motion. …
- Love-wave Motion.
Which seismic waves are the second fastest?
S-Waves. The S in S-waves stands for secondary, because they are the second-fastest seismic waves and the second type to be detected once an earthquake has occurred.
What is the name of the chart that shows seismic waves as they arrive at the station?
Seismograph. Seismographs record the arrival of earthquake waves. They operate using a shock absorbing or dampening system that allows a stabilized marker or pencil to chart the motion of the waves on paper (set on a rotating drum). The seismograph records the time of the arrival of the different types of waves.
Which seismic wave can travel in solid or liquid layers of the earth?
The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.
Why are do S-waves appear larger on the seismograph than P waves?
Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves. These are usually bigger than the P waves. … Often they are the only waves recorded a long distance from medium-sized earthquakes.
What is the highest score on the Richter scale?
In theory, the Richter scale has no upper limit, but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.).
What type of waves do seismographs measure?
A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs.
Which waves have the highest velocity?
P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth. When they travel through air, they take the form of sound waves – they travel at the speed of sound (330 ms-1) through air but may travel at 5000 ms-1 in granite.
Where do most earthquakes occur?
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
Which of the following is determined by measuring the amplitude of waves recorded from an earthquake?
Most California earthquakes occur within the top 16 km of the crust; to a first approximation, corrections for variations in earthquake focal depth were, therefore, unnecessary. The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
