Step 4: Locating the Earthquake Epicenter Using Trilateration To locate the approximate epicenter, you can use a compass, a piece of string and pencil, or electronic shape scaled to the appropriate distance for the figure.
These factors are also related to the distance of a site from the earthquake's epicenter - the point on the ground above its center. (1) Earthquake Severity or Size: The severity of an earthquake can be measured two ways: its intensity and its magnitude. Intensity is the apparent effect of the earthquake at a specific location.
The earthquake will hit you before they can do any good at all. NARRATOR: Many scientists now believe the real answer to the earthquake threat lies in engineering, not geology. In the January 2010 ...
To locate the epicenter of an earthquake, you must estimate the time interval between the arrivals of the earthquake’s P and S waves (the S-P interval) on the seismograms from three different stations. The interval is measured to the closest second and then a graph is used to convert the S-P interval to the epicentral distance.
Apr 15, 2016 · Apr 15, 2016 Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.
3. Approximately how far must an observer be from an earthquake epicenter if he or she received a . P wave 8 minutes after it was produced by the earthquake. Approximately 4800 km. 4. Explain how you could tell which of two observers was farthest from an earthquake epicenter by . comparing the arrival times of P and S waves for the two locations.
the earthquake. The effects of an earthquake increase with magnitude. Geologists use seismic waves to locate an earthquake’s epicenter. When an earthquake strikes, P waves arrive at a seismograph ﬁrst and S waves next. The farther away the epicenter is, the greater the difference between the two arrival times.

- May 01, 2011 · Earthquake P-Wave and S-Wave Travel Time Overview: When the Earth's crust quickly moves or snaps it produces an earthquake, releasing energy in the form of seismic waves that radiate out from the focus. The focus is where the crust broke. Seismic waves have different properties. The P-wave is the fastest wave, reaching distance seismographs first.

- Magnitude is measured at the source of an earthquake, while intensity is measured wherever the earthquake is felt. Often, but not always, the closer to the epicenter, the greater the intensity.
