## A Virtual Lab to be done over Winter Break

A Virtual Earthquake is an interactive site that helps you determine various important pieces of information

about an Earthquake you create. You will need to go to the following site and complete the project...

http://www.sciencecourseware.com/virtualearthquake/VQuakeExecute.html

Read all information and write the following conclusions...

1 What is the point of origin of an earthquake called

2 What were your S wave and P wave arrival times

3 How many seismograph locations are needed to locate an Earthquake's epicenter?

4 Aside from measurement errors, what other factors could result in the three circles not meeting at an exact

point?

5 Aside from the S-P interval or epicenter distance, what other informatin is needed to determine the Richter magnitude of an Earthquake?

6 From which wave, P or S, is the above information obtained?

Fill in the following chart...
