Usually the movement is not visible at the surface. When the rocks undergo a slipping event we say an Earthquake has occurred. The larger the slip the stronger the Earthquake.
Earthquakes release their energy through vibration or waves of energy.
For the Earthquake Watch you are going to do a long-term project that requires you plot the Earthquake activity every week. The coordinates for the Earthquake epicenter are given, along with the magnitude. The coordinates are given in degrees and minutes, and the magnitude is given on a scale from one to ten. The weakest magnitude being one and the strongest being ten. This data will be used throughout the year.
