It is important because with the three siesmograpghs measure the epicenter of the earthquake.

Why do scientists need three seismographs?
It takes three seismographs to locate an earthquake. Scientists use a method called triangulation to determine exactly where the earthquake occurred. If a circle is drawn on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter.
Do seismographs monitor earthquakes?
Scientists use seismographs to monitor earthquakes. Though, a seismograph merely registers an earthquake. By using at least three seismograph stations, and using triangulation, the epicentre of the earthquake is able to be plotted.
How do scientists prevent and warn tsunamis?
If the tsunami is the result of an earthquake, then scientists take three locations that the earthquake hit. They find a radius by finding out how long it took for P waves and S waves to hit the land. Once they've drawn circles, calculated by the radius, around all three locations there is an epicenter. This is where all three circles intersect. They then have seismographs that show the damage of the earthquake by a Moment Magnitude Scale. Then they predict that a tsunami will follow shortly after and they warn the countries in danger.
Why are there no warnings before an earthquake?
The problem is the nature of an earthquake. They are shifts along fault lines that can just start moving at will. There is often some indication that these are about to occur though. Sensors can show us that the fault line is felling stress about three minutes before the earthquake actually occurs. This is still an emerging science though, so more research is needed before this is used to predict future events.
How many stations do you need to locate the epicenter of the earthquake?
Three
How many seismographs are needed to detect an earthquake?
three
What is the fewest number of seismographs stations that are needed to locate the epicenter of an earthquake?
Three seismographs stations are needed to pinpoint the location of the epicentre of an earthquake.

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.
What are the three main types of seismographs?
The three types of the Seismographs are: - magnitude,shaking and focus.
Where earthquake geographic location?
the epicenter of the earthquake is where the earthquake hit. technically, you need three epicenters the find where the earthquake actually hit, though. Edit: The epicenter is the location on the surface traced to by seismographs for people to get an idea of where the earthquake happened. The hypocenter is where the earthquake actually happened below the surface.
How many seismographs do you need to find an epicenter?
You would need at least three different seismometer locations to triangulate an earthquake's location.
How can geologists tell where the epicenter of an earthquake is?
The epicenter refers to the point on the earth's surface above the focus of an earthquake. Geologists determine the epicenter with the use of 3 seismographs. This method is called triangulation.
How do scientists prevent and warn tsunamis?

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.
