Geologists use circles to find the epicenter of an earthquake what does the center of each circle re?
Focus Center
Why do three circles show the epicenter of an earthquake?
Each circle is actually the radius around a reporting station. To find an earthquake's epicenter, you need at least three reporting stations. The radius around each station should meet at one point, the epicenter. This point should be about the size of a town, depending on how close or far the reporting stations are. With any less than three reporting stations, the exact point of the epicenter may not be located.
How does a seismologist use trigonometry to measure seismic waves?
Three earthquake detecting locations, usually the three closest seismographs all record a reading for how long it took the p then s waves to get there and how strong they are. With a compass, a circle or arc is created around each station depending on its distance from the epicenter based on the data. The point where the three circles intersect to create a triangle type figure is where the epicenter is. You can then connect the three stations into a triangle and get more accurate date from the side lengths and angles to the epicenter.
How are euler circles simalair to venn diagrams?
They both use circles to represent sets of data.
What is the word for a diagram that uses overlapping circles to represent sets and their relationship?
A Venn diagram
How do geologist locate the epicenter of earthquakes?
Geologists use circles to find the epicenter of an earthquake.

Focus Center
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 is needed to find the epicenter of an earthquake?
You are suppose to pin point the three circles
What type of data do geologists use to locate an earthquake's epicenter?
Seismologists use the data from triangulated seismographs to locate an earthquake's epicenter. The difference in time between the arrival of p and s waves at a seismometer tells the distance to the epicenter of an earthquake. To get the exact location, scientists must collect data from at least three seismometers. The point where all three circles is the epicenter of the earthquake. +++ The Epicentre is generally obvious: it is the point of maximum disturbance on the surface. The centre of the actual slip is the Focus, and this has to be calculated from seismograph data by triangulating from wave velocities.

What is the process that is used to find an earthquake's epicenter?
Triangulation. First, they calculate the time between the first and second - primary and secondary - seismic waves created in an earthquake and use this information to determine how far the seismometer is from the epicenter of the earthquake. A circle is drawn around the seismometer so that it is in the center and the radius is equal to the calculated distance. Using this information from three different seismometers, two more circles are drawn and the intersecting point of the three circles is where the epicenter of the earthquake is located.
How many seismographs must be used to locate the epicenter of an earthquake?
Three sizemographs are needed to accuratley locate the earthquake's epicentre, the way to work it out is you draw three radi from the siesmographs to where the earthquake roughly is then you draw circles from that, the point where the three circles overlap is the epicentre.

Why are seismographs stations needed to determine the location of an epicenter?
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.

How does earthquake prediction work?
When 3 different earthquake stations have a radius of the area of the quake. When combined, there should only be one area overlaping with all 3 circles (radius that the stations measured) and where it overlaps, there is your epicenter. :)
