All the waves!!
Surface waves, specifically Love waves and Rayleigh waves, typically show the highest amplitude on a seismograph during an earthquake. These waves travel along the Earth's surface and cause the most shaking and ground displacement, leading to larger amplitudes being recorded.
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.
A seismograph does not record specific details about the location where an earthquake occurs. It also does not record information about the size or type of objects or buildings affected by the earthquake. Additionally, a seismograph does not provide information about the cause of the earthquake.
A seismograph records seismic waves generated by earthquakes, explosions, or human activities. It captures data such as the time, duration, and amplitude of these seismic waves to provide information about the location and magnitude of the seismic event.
A seismometer, sometimes known as a seismograph, in modern day is usually inertial an it has: 1) A weight of some kind, called the inertial mass, that moves inside but stays attached. 2) A recording device for the mass. Basically, the motion in the ground, even very slight, will move this weight and it is the movement of the weight which causes a reading on changes underground. Some modern systems now use electronics. Instead of a writing device for recording, it uses magnetic strips to record information. A seismograph records data from an earthquake with a needle and ink. When an earthquake occurs ts records this data and uses the needle with ink on it to show the highs and lows of the P waves, S waves, and surface waves the earthquake produces. The ink lines are recorded on graph paper showing the number of how high or low the earthquake's strength is and measures the waves.
Rogue waves might be produced during storm conditions. They are also known as killer waves. They are waves whose height is more than twice the significant wave height.
A wave. You make sound waves when you speak, the ocean has waves on its surface and you can have waves in your hair.
A microphone typically uses electrical energy, converting sound waves into electrical signals that can be amplified and recorded.
They are transverse waves.
They are tranverse waves.

The Richter scale was invented, logically enough, in the 1930s by Dr. Charles Richter, a seismologist at the California Institute of Technology. It is a measure of the largest seismic wave recorded on a particular kind of seismograph located 100 kilometers (about 62 miles) from the epicenter of the earthquake.
