Seismologists use seismograms to calculate when an earthquake started. AND EARTHQUAKES START WHEN ROCK SLIPS SUDDENLY ENOUGH ALONG A FAULT TO CREATE SEISMIC WAVES!

How do seismologists determine the type of waves produced by earthquakes?
they use a stick thing and stick it in the ground so the line meter thing goes squiggly
How do geologist locate the epicenter of an earthquake?
This job would normally be undertaken by a type of geophysicist known as a seismologist rather than a geologist. For information on how seismologists locate seismic waves, see the related question.
What system do seismologists use today for rating the magnitude of an earthquake?
Earthquake magnitudes are rated using the moment magnitude scale. Moderate and small earthquakes (those with a magnitude below 7) are also measured using the Richter scale. Please see the related question for more information.
What is the method that scientists use to determine the epicenter of an earthquake?
The maximum intensity is at the epicenter. It is how the scientists calculate the epicenter.
What do seismologists measure?
A seismograph is a device that scientists use to measure earthquake severity. It also determine the origination of the tremor and magnitude.
Do Geologists use the difference in the arrival time of P and S waves at a seismograph to determine the magnitude of an earthquake?
No. Seismologists (a type of geophysicist) use the difference in the arrival time of P and S waves to estimate the distance from the seismometer station to the epicentre of the earthquake.
What is the simplest method seismologists use to find an earthquake's epicenter?
The S-P time method is perhaps the simplest method seismologists use to find an earthquake's epicenter. +++ No it's not. That finds its Focus. The Epicentre is the point of maximum movement on the land surface above the slip itself.
how do scientists determine earthquake location and how do they use this information?
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
What scale do you use to determine in the magnitude of an earthquake?
Ritcher Scale
What is used to determine the earthquakes intensity?
Seismologists estimate earthquake intensity based on the reports of witnesses on the level of felt ground movement, on the amount of damage caused by an earthquake and also based on the ground accelerations as measured by seismometers. The scale used to define earthquake intensity in much of the world is the Modified Mercalli scale (before this, a scale known as the Rossi-Forel scale was used). In Europe the Macroseismic scale is in use.

Who uses seismograph?
seismologists
When did people started to use the earthquake weathercock?
in 130 bc
Describe the scales that scientists use to measure the magnitude of an earthquake?
The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
How do geologist locate the epicenter of an earthquake?
This job would normally be undertaken by a type of geophysicist known as a seismologist rather than a geologist. For information on how seismologists locate seismic waves, see the related question.
What tools do seismologists use?
Seisometers are used to measure how much the ground moves, but the only real way to detect them is to look at previous records as to how long it has been since an earthquake; if it a long time, an earthquake could happen soon.
What system do seismologists use today for rating the magnitude of an earthquake?
Earthquake magnitudes are rated using the moment magnitude scale. Moderate and small earthquakes (those with a magnitude below 7) are also measured using the Richter scale. Please see the related question for more information.
