The record of an earthquake obtained from a seismic instrument is a?
A seismogram is a record of an earthquake that's obtained from a seismic instrument. It's in the form of a graph.
What is a record of an earthquake's seismic waves on paper?
"Shake, Rattle, and Roll". But seriously folks, it's called a "seismogram".
How do you use circles to find the epicenter of an earthquake?
Scientists can calculate the distance that an earthquake occurs from a seismometer station by looking at the record of the seismic waves and measuring the difference in time between the arrival of P and S-waves. This gives them a distance but not a direction. So they plot this distance on a map by drawing a circle round the seismometer station. The radius of this circle is equal to the distance to the epicentre. If this is done for one other seismometer station that has recorded the earthquake then the circles will intersect in two places. If you add in a 3rd station and so a third circle they will all intersect in one place - the epicentre of the earthquake. In reality this process is automated by computer and lots of readings from lots of stations are used.
What can sesismographs do?
Seismographs record the arrival time and amplitude of seismic waves. They can be used to locate the earthquakes epicentre and estimate the earthquake's magnitude. Please see the related question.
What is the basic concept of the seismic instruments?
The basic concept of seismic instruments is to record vibrations. Older machines use paper, ink, and a drum to record the level of vibrations.
The record of an earthquake obtained from a seismic instrument is a?
A seismogram is a record of an earthquake that's obtained from a seismic instrument. It's in the form of a graph.
What is a seismograph station?
A seismograph station is a facility equipped with seismographs to detect and record earthquakes, tremors, and other seismic activities. These stations are strategically located to monitor seismic events and are crucial for studying and understanding earthquakes.
Seismographs?
this is where the seismic waves recorded; measures vertical earth motion
Why do we record seismic waves?
To try to predict earthquakes, and get advanced warning of them.
What is 2D seismic?
On the drum of a seismic recorder, the pen moves up or down according to the earthquake waves reaching it, giving a 2D record.
What is the written record of earthquake called?
If you are referring to the record printed on a chart by a seismograph, it is called a seismogram. If you are referring to a hand-written record of the events of an earthquake, this might be referred to as a journal.
What is siesmogram?
A seismogram is a record of ground motion produced by seismic waves from an earthquake or another source. It typically shows the amplitude and frequency of the seismic waves over time, helping seismologists analyze and understand the earthquake's characteristics.
What does seismometer station mean?
A seismometer station is a facility equipped with seismometers, instruments that detect and record ground motion from seismic waves generated by earthquakes or other sources. These stations are strategically located worldwide to monitor and study seismic activity. The data collected from seismometer stations help scientists assess earthquake hazards and understand the Earth's internal structure.
What measures how much ground movement during an earthquake?
Seismometers measure ground movement during an earthquake. These instruments detect and record the vibrations caused by the seismic waves generated by the earthquake.
What is the scientific method of scientists use instruments to record the strength of earthquakes in an area?
Scientists use seismometers to record the seismic waves produced by earthquakes. These instruments measure the strength, duration, and frequency of seismic waves, helping scientists determine the earthquake's magnitude and location. The data collected from these instruments are crucial for understanding seismic activity and improving earthquake prediction and response strategies.
Where was the epicentre located?
The epicenter of an earthquake is the point on the Earth's surface directly above the focus (hypocenter) of the earthquake. It's location can be pinpointed using seismographs that record the seismic waves.
What do you use to measure the power of an earthquake?
The power of an earthquake is measured using a seismometer to record the seismic waves produced by the earthquake. The magnitude of an earthquake is typically measured using the Richter scale or moment magnitude scale.
