How can you use a graph of earthquake waves travel distance and time to find an epicenter?
Not easily because
- The speed at which waves travel depends on the medium that they are travelling through. For example, the speed is affected by whether or not the wave travels through the mantle or the core.
- The waves are often reflected back to the surface from the core-mantle boundary.
- The direction of the wave is affected by diffraction because its speed of propagation varies with the density of the medium.
But there are statistical models being developed to get around these problems.

How do seismologists align the seismogram with the time-distance graph?
Seismologists align the seismogram with the time-distance graph by identifying the arrival times of seismic waves, specifically the Primary (P) and Secondary (S) waves, on the seismogram. They measure the time difference between these wave arrivals to determine the distance to the earthquake's epicenter using the time-distance graph, which correlates these arrival times to distances. By matching the observed arrival times on the seismogram with the corresponding distances on the graph, they can accurately locate the earthquake's source. This process helps in understanding the event's magnitude and depth.
What are the steps of the S-P time method?
The S-P time method is used to determine the distance to an earthquake epicenter. The first step is to measure the time difference between the arrival of the primary (P) waves and the secondary (S) waves at a seismograph station. The second step is to use a travel-time graph to determine the distance to the epicenter based on the time interval between the P and S waves. Finally, by using data from at least three seismograph stations, the exact location of the earthquake epicenter can be triangulated.
What does the time-distance graph of seismic waves show?
The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.
What graph shows the vibrations caused by an earthquake?
A seismograph is the graph that shows vibrations caused by an earthquake. It records the movement of the ground in a vertical direction as the seismic waves pass through the Earth's crust.
What does the slope of a time vs distance graph equal?
The slope of a time vs distance graph represents the speed or velocity of an object. It is calculated as the change in distance divided by the change in time. A steeper slope indicates a greater speed.

How do scientists locate the epicenter of an earthquake by s-p time method?
They first collect several seismogram tracings of the same earthquake from different locations. Then the seismograms are placed on a time distance graph. The seismogram tracing of the first p wave is lined up with the p wave time distance curve. The difference from each station from the earth quake can be found by reading the horizontal axis. After finding out the distance, a seismologist can locate an earthquake's epicenter.
How do you figure out the distance of an epicenter?
The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.

What is a curved graph?
A curved graph is a graph usually used to find the earthquake's epicentre. It involves finding the time of the earthquake, (P-S waves) and then plotting that onto the graph. So when your time hits the curve you simply measure straight down and that's you distance from the earthquake. Easy!
