4. What are Earthquakes?
Earthquake: The shaking or trembling of the ground caused by the sudden movement (release of energy)
Usually associated with faulting or breaking of rocks due to stress
Continuing adjustment of position results in aftershocks

5. What is a fault?
Fault: is a fracture, or break in the Earth’s lithosphere, along which blocks of rock move past each other
Types of faults –
Normal Fault - tension
Reverse Fault - compression
Strike-Slip Fault - shearing

6. What is stress?
Stress: is the amount of force exerted when an object presses on, pulls on, or pushes against another object

7. How does pressure affect a solid material?
Turn to page 45 in your “The Changing Earth” textbook.

8. Where do most earthquakes occur?
This map show the locations of moderate to intense earthquakes from

9. Ring of Fire
Pacific Ocean

10. Types of Faults
Normal Fault – the block of rock above the fault plane slides down relative to the other block of rock.
These faults occur near divergent boundaries
Stress (tension) pulls the rocks apart
Earthquakes are common
Example: Great Rift Valley in Africa

11. Types of Faults
Reverse Fault – the block of rock above the fault plane moves up relative to the other block of rock.
Stress(compression) that presses the rock together causes a reverse fault
These faults occur near convergent boundaries
Example: Himalaya Mountains – the Indian Plate is pushing into the Eurasian Plate

12. Types of Faults
Strike-Slip Fault – blocks of rock move sideways on either side of the fault plane
Stresses (shearing) that push blocks of rock horizontally cause earthquakes
These faults occur where plates scrape past each other
These faults occur near transform boundaries
Example: The San Andreas Fault in California

13. Magnitude
Richter Scale - Scale developed in California during the 1930’s by scientist Charles Richter and Beno Gutenberg
Based on a scale of 0-10
8 or higher is considered extremely powerful
Magnitude is based on how fast the ground moves at a seismic station
Moment Magnitude Scale – based on the total amounts of energy released by earthquakes
New more accurate scale used (used in our book to measure magnitude)
For each scale, an increase of one whole number indicates an increase of 32 times as much energy than the previous number
Example - magnitude 5 EQ releases 32 times more energy than a magnitude 4 EQ
Mercalli Scale - The effect of an earthquake on the Earth's surface is called the intensity. The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction.

17. A smaller EQ that follows a more powerful EQ in the same area
Aftershock
A smaller EQ that follows a more powerful EQ in the same area
Other damage – broken pipes and fires can cause great damage after an EQ
The moving of the ground usually does not injure people – they are injured/killed by building collapsing on them

18. The Focus and Epicenter of an Earthquake
Focus - The point within (inside) Earth where faulting/breaking of rock begins or hypocenter
Epicenter – The point directly above the focus (where rocks break and move) on the surface is the epicenter

19. Waves of energy released as vibrations caused by an earthquake
Seismic Waves
Waves of energy released as vibrations caused by an earthquake

20. Seismic Waves Primary Waves (P waves) Secondary Waves (S waves)
Fastest (arrive first)
Travel through liquids & solids
Push and pull waves
Secondary Waves (S waves)
Arrive second
Cannot travel through liquid

21. Seismic Waves Surface Waves Move along the Earth’s surface
Not through the interior
Make the ground roll up and down
Largest movements
Cause the most damage

22. Seismographs
Seismograph – is an instrument that constantly records ground movements
Separate seismographs record side-to-side movements and up-and–down movements
When the ground moves in an earthquake, the heavy weight moves and the pen attached to the weight records the movements
Turn to page 57 in your book

23. Liquefaction
Liquefaction – a process in which shaking of the ground causes soil to act like a liquid
Soil becomes like a thick soup
Occurs in areas where the ground is made up of loose sand and silt and contains large amounts of water

24. Tsunami
Tsunami – a wave of water triggered by an earthquake, volcanic eruption or landslide
Sometimes called tidal waves
Can be several waves that arrive hours apart

25. Predicting Earthquakes
Can only give long term predictions based on the EQ risk of an area
Scientists monitor stress along faults
Tilts or changes in the elevation of the ground
Slow movements or stretching in rock
The development of small cracks in the ground

26. Earthquake –Resistant Buildings
Base-isolators – placed between a building and its foundation. They are flexible layers that are stacked
Open space/moat – open space give the building room to shake
Shear walls – add strength to the structure with steel supports
Cross braces – X shaped braces help building keep its shape during shaking
