What is used to determine the Richter magnitude of an earthquake?
The amplitude of seismic waves as measured by a seismometer.
How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
Given the difference in arrival times, you can determine the distance from the epicenter.
Whats the difference between the epicenter of an earthquake and the focus of the earthquake?
The focus of an earthquake is the place where an earthquake occurred along the fault underground, while the epicenter is the place directly above it where the seismic waves were felt.The focus is where an earthquake starts and the epicenter is where the earthquake hits the hardest.The focus of the earthquake is where the actual earthquake occurred and the epicenter is on the ground directly above the focus. The epicenter is used to say where the earthquake was in relation to places near where it occurred.
What is the method used to figure out the epicenter of an earthquake?
epicenter and seiesmic waves, find the distance and seismograph stations
What is the term used to define the exact location of an earthquake?
epicenter
What is the minimum number of seismic stations needed to determine the location of an earthquake and epicenter?
you need to have 3 seismic stations to triangulate the location of the earthquake and remember a earthquake can be from the inside of the earth but not necessarily at the epicenter because no epicenter is a straight line down.
How can be determined the earthquake epicenter from seismic waves?
The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.
A travel-time graph can be used to find the?
The distance of an earthquake epicenter from a seismic station. Using the Three point method, the distance from 3 seismic stations are used to locate the epicenter by triangulation.
A travel-time graph can be used to find the .?
The distance of an earthquake epicenter from a seismic station. Using the Three point method, the distance from 3 seismic stations are used to locate the epicenter by triangulation.
How can seismic waves be used to determine an earthquake's epicenter?
The epicenr can be found by location the sound in the waves carried.
The method used to determine the epicenter of an earthquake is called?
earth method
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 process that is used to find an earthquake's epicenter?
Triangulation. First, they calculate the time between the first and second - primary and secondary - seismic waves created in an earthquake and use this information to determine how far the seismometer is from the epicenter of the earthquake. A circle is drawn around the seismometer so that it is in the center and the radius is equal to the calculated distance. Using this information from three different seismometers, two more circles are drawn and the intersecting point of the three circles is where the epicenter of the earthquake is located.
What type of wave can be used to determine the location of an earthquake focus?
Seismic waves can be used to determine the location of an earthquake focus. These waves are triggered by tectonic plates.
What is used to determine the Richter magnitude of an earthquake?
The amplitude of seismic waves as measured by a seismometer.
How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
Given the difference in arrival times, you can determine the distance from the epicenter.
Whats the difference between the epicenter of an earthquake and the focus of the earthquake?
The focus of an earthquake is the place where an earthquake occurred along the fault underground, while the epicenter is the place directly above it where the seismic waves were felt.The focus is where an earthquake starts and the epicenter is where the earthquake hits the hardest.The focus of the earthquake is where the actual earthquake occurred and the epicenter is on the ground directly above the focus. The epicenter is used to say where the earthquake was in relation to places near where it occurred.
