Web Quests # 1-4 Earthquake activity--- 
Mammoth Lakes, Calif.
We live in a region of  major earthquake activity.    California borders the Pacific Rim of Fire. In this lesson  you will explore recent data of the Mammoth Lakes area of California by using web resources.  You will be given specific task and instructions. You may use the resources on this page or you can use the Search engines to find what you are looking for. Remember to make reference of all the web sites that you use during this web quest. Recordthe URL and a brief description of each site that you use. Use worksheet and graph paper to record your data. Your first web site will provide information commonly used to describe earthquakes. On your worksheet record a brief description of the following terms: Aftershocks, Crust, Epicenter, Fault, Intensity, Magnitude, Richter Scale, Thrust, Strike slip.Tsunamis, Uplift, Waves.
