How does triangulation determine the epicenter of an earthquake quizlet?
How does triangulation determine the epicenter of an earthquake? On a map, a circle is drawn around each of three recording stations, with the radius being the distance from the station to the epicenter of the earthquake. The epicenter is located where the three circles intersect.
How do you determine the epicenter of an earthquake?
Finding the Distance to the Epicenter Measure the distance between the first P wave and the first S wave. In this case, the first P and S waves are 24 seconds apart. Find the point for 24 seconds on the left side of the chart of simplified S and P travel time curves and mark that point.
What is triangulation in earthquakes?
Triangulation is a method that uses distance information determined from 3 seismic stations to uniquely locate the earthquake. On a map, circles are drawn around each seismic station. The radius of the circle are scaled to the estimated distance from the station to the earthquake.
What are the four steps in finding the epicenter of an earthquake?
MatchFirst step of finding epicenter. Collect data from 3 different seismographs.Second step of finding epicenter. Find the difference between the arrival time of the P and S waves.Third step of finding epicenter. Use the P and S graph to find the distance to the epicenter.Fourth/Last step of finding epicenter.
Who first explained the mechanism by which most earthquakes are generated?
H. F. Reid first explained the mechanism by which most earthquakes are generated by conducting a landmark study shortly after the 1906 San Francisco earthquake.
How much more energy does an earthquake release than an earthquake with a magnitude of 8.0?
How much more energy does a magnitude 8.0 earthquake release than does a magnitude 7.0 earthquake? An earthquake with a magnitude of 8.0 releases 32 times more energy than an earthquake with a magnitude of 7.0.
What is the exact point underground along a fault where the slippage of the two blocks of rock occurs?
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 .
What is the difference between the Richter scale and the Moment Magnitude Scale?
The moment magnitude scale measures the total energy released, whereas the Richter scale only measures the amplitude of the largest seismic wave.
How much more energy does an earthquake release?
An earthquake with a magnitude of 8.0 releases 32 times more energy than an earthquake with a magnitude of 7.0.
What is elastic rebound?
Elastic rebound refers to how the slippage along a fault (i.e., earthquake) allows the deformed rock to regain its original shape in a new location.
How does a seismograph work?
A seismograph works by suspending a weight from bedrock, which remains motionless during an earthquake. A rotating drum that is affixed to the moving bedrock moves as the rock moves, recording the relative displacement between the stationary weight and the rotating drum.
