What do scientists locate when they draw circles around three seismometer stations and find where the circles intersect?

The question, as posed, makes little sense. All that they would find is the points of intersection of the circles!
The question says nothing about the sizes of the circles - whether they are the same or whether they represent some measure of seismic transmissivity of the earth near (under) them.

What describes coplanar circles that intersect in exactly one point?
Tangential circles.
How many times can 2 circles with different diameters intersect?
Twice max.
What is the maximum number of points of intersection when two circles and five strait lines intersect ecah other?
32
The diameter of a larger circle is 12M what is the area of the non shaded part There are tow shaded circles in a bigger one?
It is difficult to say since there is no image and it is not clear what part is shaded. But, if there is a circle with a 12 metre diameter which contains two equal circles which are as large as possible, then the shaded area is probably 56.55 square metres.
If NO 30 mm and radius 16 mm how long is PQ a chord of both circles to the nearest tenth of a millimeter?
The question, as posted, cannot be answered because the questioner has failed to provide enough information. I suspect the question concerns two circles, each with radius 16 mm, whose centres are at N and O. The circles intersect at P and Q.If that is the question, then the chord PQ is 25.4 mm long.
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.
Why is more than 2 seismic stations needed to measure an earthquake?
Two stations each give out a circle. Those circles intersect at two places. When a third station is added, there are three circles. These three circles only intersect together at one place. That's where the precise earthquake location is.
Why are 3 seismometers required to locate exactly where an eartquake occurred?
The seismometer records the P and S-wave arrival times. P-waves travel faster through the earth than S-waves and so they arrive at the seismometer station before the S-waves and are recorded by the seismometer first. The difference in arrival time between the two types of seismic wave can be used to calculate the distance of the earthquake's epicentre from the seismometer. This can then be plotted on a map, by drawing a circle with a radius equal to the distance to the epicentre around the seismometer station. This is then repeated for the other two seismometer stations and the point where the three circles intersect is the location of the earthquakes epicentre.
Is it that if two different circles intersect then they intersect at one and only one point?
If two circles intersect then they have to intersect at two points.

Why are two seismic stations not enough?
Because you need three points to locate the source of a signal. Think of a station as the center point of a circle. The station can detect the seismic wave, and the wave's properties can tell you the distance (P and S wave measurement) but not the direction it came from. One station would give you a whole circle edge (circumference) to search for the wave's source, based on that distance (radius of the circle). But if you have a second station, you can measure the same wave there and get a second circle radius from that station. If you draw both of these circles on a map, with the stations at the circle centers, you will see that the two circles intersect at two points. This narrows the possible wave source to two places. But if you have three stations, and draw a circle around that station based on the wave measurement, there will only be one point where all three circles intersect. That point is the source of the wave the stations detected.
