How do you find the epicenter of a compass?
Using your compass draw a circle with a radius equal to the number you came up with in Step #2 (the radius is the distance from the center of a circle to its edge). The center of the circle will be the location of your seismograph. The epicenter of the earthquake is somewhere on the edge of that circle.

How do you find the epicenter of a gizmo?
Locate the epicenter of an earthquake by analyzing seismic data from three recording stations. Measure difference in P- and S-wave arrival times then use data from the Earthquakes 1 – Recording Station Gizmo to find the distance of the epicenter from each station.
What is the distance of the epicenter from the seismic station?
The distance of the seismic recording station from the earthquake epicenter is determined from the time difference between the first arrival of the P-wave and the S-wave. This is known as the S-P interval.

What is the meaning lithosphere?
The lithosphere is the solid outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
What is the seismic wave?
A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth’s surface (Rayleigh and Love waves) or through the earth’s interior (P and S waves).
Where is the epicenter of gizmo?
The Earthquake — Recording Station Gizmo™ simulates the seismic waves released by an earthquake. To begin look at the key on the bottom left side of the Gizmo. The epicenter of the earthquake is the point on Earth’s surface closest to the focus or origin of the earthquake.
Are seismic waves longitudinal or transverse?
The P seismic waves travel as elastic motions at the highest speeds. They are longitudinal waves that can be transmitted by both solid and liquid materials in the Earth’s interior.
What is hypocenter and epicenter?
The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth.
How are epicenters located?
The epicenter is the point on the surface of the Earth directly above the hypocenter of an earthquake. … The location of an epicenter can be found using three seismographs. By measuring the lag time between the P-wave and S-wave each station can calculate their distance to the earthquake. See also where did chickenpox originate from
How are faults hypocenters and epicenters related? The hypocenter is the exact point underground along a fault where the slippage of the two blocks of rock occurs. The epicenter is the point on Earth’s surface that is directly above the hypocenter.
Why does the gizmo draw a circle around each recording station?
Scientists use triangulation to find the epicenter of an earthquake. … To determine the direction each wave traveled scientists draw circles around the seismograph locations. The radius of each circle equals the known distance to the epicenter.
What is epicenter in simple words?

What is systemic wave?
A seismic wave is a wave that travels through the Earth most often as the result of a tectonic earthquake sometimes from an explosion. There are two types of seismic wave namely ‘body wave’ and ‘surface wave’. There are two kinds of body waves: primary (P-waves) and secondary (S-waves).

What is AP wave?
A P wave or compressional wave is a seismic body wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving.
How do scientists find the epicenter of an earthquake quizlet?
How do geologists locate the epicenter of an earthquake? They use seismic waves to locate an earthquake’s epicenter. Scientists measure the difference between the arrival time of the P and S waves to the seismograph. The farther away an earthquake the greater the distance between arrival time.
