Focus
• The point beneath Earth’s surface were rock breaks under stress and causes an earthquake.

Epicenter
• The point on Earth’s surface directly above an Earthquakes surface.

Seismic Waves
• A vibration that is released during an earthquake.

Primary Waves
• A type of seismic wave that moves like an accordion.

Secondary waves
• A type of seismic wave that moves the ground up and down or side to side.

Surface Waves
• A type of seismic wave formed by S & P waves when they reach the surface
![Page 8: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/8.jpg)
Seismograph
• A device that records vibrations on Earth’s surface

Magnitude
• Measurement of an earthquake’s strength based on seismic waves & movement near fault
![Page 10: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/10.jpg)
Mercalli Scale
• Scale that rates earthquakes according to their intensity & how much damage they cause
![Page 11: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/11.jpg)
Richter Scale
• A scale that rates seismic waves measured by a particular type of seismograph
![Page 12: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/12.jpg)
Moment Magnitude Scale
• A scale that rates earthquakes by estimating the total energy released by an earthquake
![Page 13: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/13.jpg)
Seismic waves
• As seismic waves travel through Earth,they carry the energy of an earthquake from the focus to the surface.
![Page 14: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/14.jpg)
Detecting Seismic Waves
• Earthquakes produce two types of seismic waves p waves and s waves that travel out in all direction from the focus of an earthquake.
![Page 15: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/15.jpg)
Measuring Earthquakes • Today the moments magnitude scale is used to
determine the magnitude of an earthquake .• Other scales that geologists have used to rate
earthquakes include the Mercalli scale and the Richter scale.
• Earthquakes produce two types of seismic waves, P & S waves, that travel out all directions from the focus of an earthquake
![Page 16: Section 2-2 Measuring Earthquakes Andrea Gonzalez Isabella Alexander Sylvia Silva Alondra Rodriguez 12/10/07](https://reader036.vdocument.in/reader036/viewer/2022062407/56649d215503460f949f706c/html5/thumbnails/16.jpg)
We Learned
• We learned that there are three different type of seismic waves,P waves,S waves,and Surface waves.
• We also learned that surface waves produce the most severe ground movements.
• Also we learned the focus and the epicenter run in a straight line.
• Finally we learned that there are three different types of seismographs Moment magnitude,Richter ,and Merrcali Scale.
