What is a seismic travel time curve?
A seismic travel time curve describes the relation between the travel time of a seismic wave and the epicentral distance. It is used to calculate the calculate the distance of the earthquake's epicenter from the seismograph.
What is the difference between epicenter and hypo center?
The epicenter is the origin of an earthquake. However, a hypocenter is the exact spot where a bomb has been dropped.
The location on earth's surface directly above the focus of an earthquake is the epicenter a close correlation exists between epicenters and plate boundaries is it true or false?
Yes, it is true that the location of the earth's surface is directly above the focus of an earthquake is the epicenter a close correlation exists between epicenters and the plate boundaries.
If a P-wave arrives 4 minutes after an earthquake occurs at the epicenter how far is the epicenter?
P-waves travel between 5-8 km/s. As such the epicentre could be anywhere between 1200 and 1920 km away.
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.
How is the distance between a seismic station and the earthquake epicenter is determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
How is the distance between the seismic station and the earthquake epicenter determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
If there are 3 records of the same earthquake how can the epicenter be determined?
The epicenter can be determined by measuring the time difference between the arrival of P and S waves, and then calculating the distance of the epicenter from each of the 3 stations. Once you have estimated the distance for each station you then draw a circle around each one. The place where the circles meet or intersect, is the epicenter.
What is the relationship between lag time and distance from an earthquake's epicenter?
The more is the time taken and the distance recorded by the seismograph, the more is the effect of an earthquake:)
Which two waves from an earthquake can triangulate the epicenter?
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival time is used to find the distance to an Earthquake's epicentre.
What is the difference between epicenter - earthquake?
An earthquake can reach several miles in distance, but the epicenter is the point of the strongest movement, usually the starting point from which it spreads. Also, the epicentre is on the ground directly above the focus. The focus is the point where the actual earthquake occurred. Hope this helped:)

What is the difference between an earthquake's fucus and epicenter?
An earthquake's focus is the point within the earth where the earthquake starts. The epicenter is the point on earth directly above the focus.
The distance between a seismological recording station and the earthquake source is determined from the?
The distance between a seismological recording station and the earthquake source is determined from the arrival time of P and the S waves. P waves are faster than S waves and surface waves.

What the difference between a epicenter and a focus?
The difference between the Focus and the Epicenter is...... The Focus is pretty much where the earthquake starts but some people say it is the center of the earthquake. But moving on the Epicenter is right above the Focus but on the crust. I hope that answered your question!!
