Lab Locating An Epicenter Worksheet Answer Key - It is located close to san diego, california. Use the travel‐time graph, figure 2, to determine the distance that each station in figure 3 is from the epicenter. The three seismograms in this activity are unfi ltered station records from a single event that occurred on august 1, 1999. To use seismic data and an interactive simulation to triangulate the location and measure the magnitude of an earthquake.

Locating The Epicenter Of An Earthquake

Answer the following questions on a separate sheet of paper. The circles you draw should intersect at one point, which is the epicenter. This can be done by drawing circles with the appropriate radius around the cities of record, and identifying where the circles intersect.

Notice The Time Scale Below E.

A second seismogram, recorded in a different location, can narrow down the possible location to some degree, but at least three seismograms are required in order to accurately plot the epicenter. Student pairs examine seismic waves, s waves and p waves recorded on seismograms, measuring the key. We locate earthquakes by looking at seismogram recordings of seismic waves, p waves and s waves, because they travel at different speeds and thus arrive at seismic stations at different times.

The Point Where The Paper Meets The Distance Scale At.

Use the scale for the world map to set this radius on the drafting compass. Refer to the data table and use the difference in. Repeat steps 4 and 5 for houston and chicago.
