can anyone help me on how a scientist would describe the steps of how to find and earthquake's epicenter?

Question

i really need help. could someone answer my question in number detail please?

Answer 1

they measure the differences of the p and s waves from an earthquake and apply that information to a graph which shows them the distance that it came from.

Answer 2

Right, they measure the difference between the p and s waves which are waves that go around the earth and ones that go through it, and they also have amplitude measurements to compute the strength, but they also have to combine the data from many stations to know the probable epicenter, and actual power of the earthquake. So what they actually do is kind of a triangulation, but with a lot more data than 2 or 3 lines. This is why it usually takes awhile for the center to be known, because the regional centers have to get the data from the smaller ones, then put it all together

Answer 3

Measuring the waves gives the location of the earthquake. The earthquake will be well below the surface so the centre of the quake is down there. The epicentre is the point on the Earth's surface above the quake.
