After an earthquake which type of seismic wave arrives first at a seismometer?
P waves (APEX)
What is the difference between a seismometer and a accelerometer?
A seismometer is the modern instrument used to measure seismic waves. A seismogram is a print out of the seismic data recorded by the seismometer. Usually in the form of the motion per unit time in all three dimensions.
Are seismic waves and tsunami the same?
A seismograph is an instrument that records movements within the earth. A seismogram is the actual recording that scientists look at when studying earthquakes.
What is the difference between a Siesmograph and a siesmogram?
SiesmographEarthquakes generate seismic waves which can be detected with a sensitive instrument called a seismograph. Advances in seismograph technology have increased our understanding of both earthquakes and the Earth itself.Perhaps the earliest seismograph was invented in China A.D. 136 by a m an named Choko.How Do I Read a Seismogram?When you look at a seismogram, there will be wiggly lines all across it. These are all the seismic waves that the seismograph has recorded. Most of these waves were so small that nobody felt them. These tiny microseisms can be caused by heavy traffic near the seismograph, waves hitting a beach, the wind, and any number of other ordinary things that cause some shaking of the seismograph. There may also be some little dots or marks evenly spaced along the paper. These are marks for every minute that the drum of the seismograph has been turning. How far apart these minute marks are will depend on what kind of seismograph you have.Figure 1 - A typical seismogram.So which wiggles are the earthquake? The P wave will be the first wiggle that is bigger than the rest of the little ones (the microseisms). 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.Figure 2 - A cross-section of the earth, with earthquake wave paths defined and their shadow-zones highlighted.If there aren't any S waves marked on your seismogram, it probably means the earthquake happened on the other side of the planet. S waves can't travel through the liquid layers of the earth so these waves never made it to your seismograph.The surface waves (Love and Rayleigh waves) are the other, often larger, waves marked on the seismogram. They have a lower frequency, which means that waves (the lines; the ups-and-downs) are more spread out. Surface waves travel a little slower than S waves (which, in turn, are slower than P waves) so they tend to arrive at the seismograph just after the S waves. For shallow earthquakes (earthquakes with a focus near the surface of the earth), the surface waves may be the largest waves recorded by the seismograph. Often they are the only waves recorded a long distance from medium-sized earthquakes.
What scale rates the size of seismic waves?
Most scientists use a machine called a seismograph which has a pen on the end and moves when there is shaking from the seismic waves. It records the shaking on a rotating paper called a seismogram. The up and down lines you see sometimes are drawn by the seismograph.
What produces a record of seismic waves?
seismogram-
Seismograph and seismogram?
a seismograph records the pattern of shcok waves on a revolving drum of paper.ans tracing on the paper is known as seismogram
What is a record of an earthquake's seismic waves on paper?
"Shake, Rattle, and Roll". But seriously folks, it's called a "seismogram".
A seismogram shows that p waves travel?
P waves travel through solids, liquids, and gases. it is the fastest of all the waves.
Diagram to show the epicentre and the focus of an earthquake?
A record of the waves co used by an earthquake is called seismogram the diagram above shows simplified seismogram
How does a seismogram show earthquakes waves?
By a pen moving on a piece of paper to show the magnitude
How do you understand what all the squiggly lines on a seismogram mean?
A seismograph records large P waves that are the fastest waves then it will recorded S waves which are bigger than the P Waves. Followed by surface waves.
How do you read a seismogram?
A seismograph is used to delete seismic waves under the surface of the Earth. It helps seismologists to determine the locations of earthquakes.
The trace that records an earthquake from seismic instruments is called a?
the ground movement caused by seismic waves
Is seismogram common or proper noun?
Seismogram is a proper noun.When you type Seismogram you capitilize the S.
After an earthquake which type of seismic wave arrives first at a seismometer?
P waves (APEX)
What is the tracing of earthquake motion made by a seismograph called?
the motion is called seismogram
