Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.
The word derives from the Greek σεισμός, seismós, a shaking or quake, from the verb σείω, seíō, to shake; and μέτρον, métron, measure and was coined by David Milne-Home in 1841, to describe an instrument designed by Scottish physicist James David Forbes.
Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated.
Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.
Geophysicist Horst Rademacher explains how a simple seismograph records the Earth’s shaking.

How Does A SEISMOGRAPH Work
A seismograph is an instrument used to detect and record seismic waves, which are vibrations in the Earth's crust caused by various geological phenomena, such as earthquakes, volcanic activity, or human-induced events like explosions. The basic principle behind a seismograph is to measure the ground motion caused by these seismic waves.
Here's a general overview of how a seismograph works:
Sensor (Seismometer): The primary component of a seismograph is the sensor, also known as a seismometer. This device is designed to detect ground motion. Traditional seismometers use a mass suspended within a stationary frame. When the ground shakes, the frame moves, but the suspended mass tends to remain in place due to its inertia. The relative motion between the frame and the mass is then record...

Horrible today: YELLOWSTONE IS SHAKING! Hundreds of Earthquakes, Hit National Park in 24 Hours
Yellowstone is one of the most seismically active areas in the United States. Approximately 900 to 3,000 earthquakes occur each year in the Yellowstone area; most are not felt. They result from the extensive network of faults associated with the volcano and surrounding tectonic features.
Yellowstone earthquakes tend to occur in swarms—close together in time and space. This phenomenon is related to transport of volcanic fluids along the many small fractures in the shallow rocks over the magma, a pattern that has been noted in volcanos around the world.

==Display Info==
An alert tone will sound if a possible earthquake has been detected. The tone will change pitch and sound longer the stronger the motion that is detected.
The lower graph (black line) will show smaller motion. Either smaller local quakes or larger more distant earthquakes. The graph is set to a fixed scale. The larger the motion detected, the more the graph will be filled.
The graph above the lower graph (blue line) is a variable scale graph. The graph's scale will shrink and grow as the signal level changes.
The color graph is a Spectrogram. This is a different way to view the same seismic data. See the info links for information on how to interpret this graph.

The SoCal spectrograms display USGS seismic stations around Southern California.
The gauge shows the current 'count' value of the 4d's geophone. Count definition: “Counts” is the raw number read off the physical instrument, ie. the voltage read from a sensor.
Below the gauge are three lights that will show red if any of the 4D's accelerometer sensors detect feelable ground motion here. One for Vertical motion, one for North/South motion, and one for East/West motion. I estimate it will take about 80,000 to 100,000 counts to begin to motion felt here.

A seismograph is an instrument used to detect and record seismic waves, which are vibrations in the Earth's crust caused by various geological phenomena, such as earthquakes, volcanic activity, or human-induced events like explosions. The basic principle behind a seismograph is to measure the ground motion caused by these seismic waves.
Here's a general overview of how a seismograph works:
Sensor (Seismometer): The primary component of a seismograph is the sensor, also known as a seismometer. This device is designed to detect ground motion. Traditional seismometers use a mass suspended within a stationary frame. When the ground shakes, the frame moves, but the suspended mass tends to remain in place due to its inertia. The relative motion between the frame and the mass is then recorded.
Ground Motion Detection: The seismometer's sensor can detect ground motion in three dimensions: side-to-side (north-south), up-and-down (vertical), and back-and-forth (east-west). Modern seismometers often use sensitive electronic sensors or accelerometers to measure these movements.
Recording Device: The detected ground motion is then recorded on a recording device. In the past, this was often done using a rotating drum with paper and an attached pen or ink stylus. As the drum rotates, the pen or stylus moves up and down, creating a seismogram – a visual representation of the seismic waves over time.
Digital Seismographs: In more modern systems, the analog signals from the seismometer are converted into digital data and recorded electronically. Digital seismographs offer advantages in terms of data storage, transmission, and analysis.
Data Analysis: Seismologists analyze the recorded data to determine various characteristics of the seismic event, such as its magnitude, location, depth, and the type of waves generated.
Seismographs are crucial tools in earthquake monitoring and research. They help scientists understand the behavior of seismic waves, study the Earth's interior structure, and provide early warnings for potential earthquake hazards. The data collected from seismographs contribute to our understanding of earthquake dynamics and improve our ability to mitigate the impact of seismic events.

Yellowstone is one of the most seismically active areas in the United States. Approximately 900 to 3,000 earthquakes occur each year in the Yellowstone area; most are not felt. They result from the extensive network of faults associated with the volcano and surrounding tectonic features.
Yellowstone earthquakes tend to occur in swarms—close together in time and space. This phenomenon is related to transport of volcanic fluids along the many small fractures in the shallow rocks over the magma, a pattern that has been noted in volcanos around the world.

Seismometers are instruments that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.
The word derives from the Greek σεισμός, seismós, a shaking or quake, from the verb σείω, seíō, to shake; and μέτρον, métron, measure and was coined by David Milne-Home in 1841, to describe an instrument designed by Scottish physicist James David Forbes.
Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated.
Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.
