THE AREA WHERE SLIPPAGE FIRST OCCURS ALONG A FAULT
WHAT IS THE FOCUS?
A SERIES OF SMALL TREMORS FOLLOWING AN EARTHQUAKE
WHAT IS AN AFTERSHOCK OR MICROQUAKE?
90% OF CONTINENTAL EARTHQUAKES HAVE THIS KIND OF FOCUS WHICH ALSO CAUSES THE MOST DAMAGE
WHAT IS A SHALLOW FOCUS?
MOST QUAKES OCCUR NEAR THESE
WHAT IS A PLATE BOUNDARY?
ACCORDING TO THIS THEORY ACCUMULATED STRESS CAUSES ROCK TO DEFORM OR FRACTURE AND THEN SPRING BACK INTO THEIR ORIGINAL SHAPE CAUSING AN EARTHQUAKE
WHAT IS THE ELASTIC REBOUND THEORY?
A GROUP OF INTERCONNECTED FAULTS
WHAT IS A FAULT ZONE?
THIS CIRCULAR AREA INCLUDES THE WEST COASTS OF NORTH & SOUTH AMERICA, EASTERN ASIA, & THE WESTERN PACIFIC ISLANDS DAILY DOUBLE!!!!
WHAT IS THE PACIFIC RING OF FIRE?
OCEANIC CRUST PULLS AWAY FROM BOTH SIDES OF THIS AREA
WHAT IS A MID-OCEAN RIDGE?
THIS FAULT EXTENDS ALONG MUCH OF THE LENGTH OF CALIFORNIA
WHAT IS THE SAN ANDREAS FAULT?
COMPRESSION, TENSION & SHEARING
WHAT ARE 3 TYPES OF STRESS FORCES ACTING ON ROCK?
THIS TOOL RECORDS ENERGY RELEASED BY AN EARTHQUAKE
WHAT IS A SEISMOGRAPH?
THIS IS A SCIENTIST WHO STUDIES EARTHQUAKES
WHAT IS A SEISMOLOGIST?
AT LEAST THREE OF THESE ARE NEEDED TO LOCATE THE EPICENTER OF AN EARTHQUAKE
HOW MANY SEISMOGRAPH STATIONS ARE NEEDED TO LOCATE THE EPICENTER OF AN EARTHQUAKE?
THIS KIND OF GRAPH IS USED TO DETERMINE THE EPICENTER OF AN EARTHQUAKE
WHAT IS A DISTANCE TIME GRAPH?
TO DETERMINE HOW FAR AWAY FROM A SEISMOGRAPH STATION AN EARTHQUAKE OCCURRED, SCIENTISTS PLOT THE DIFFERENCE BETWEEN THESE 2 WAVES
WHAT ARE P & S WAVES?
THIS IS AN APPROXIMATE MEASURE OF HOW MUCH ENERGY THE EARTHQUAKE RELEASES
WHAT IS THE MAGNITUDE?
A MAGNITUDE OF 2.5 OR LESS, WHICH CANNOT BE FELT BY PEOPLE
WHAT IS A MICROQUAKE?
DAILY DOUBLE!!!!!!!!!! THIS SCALE PROVIDES VALUES FOR THE MAGNITUDE OF AN EARTHQUAKE
WHAT IS THE RICHTER SCALE?
THESE WAVES CAUSE THE MOST DAMAGE
WHAT ARE SURFACE WAVES?
A 7 OR ABOVE ON THE RICHTER SCALE
WHAT IS A MAJOR EARTHQUAKE?
THESE WAVES ARRIVE FIRST AT A SEISMOGRAPH STATION
WHAT ARE PRIMARY, OR P WAVES?
THESE WAVES CAN ONLY TRAVEL THROUGH THE LITHOSPHERE, OR ANY SOLID
WHAT ARE SECONDARY WAVES, OR S WAVES?
THESE ARE COMPRESSION SEISMIC WAVES
WHAT ARE P WAVES?
THESE WAVES ARE THE LAST TO GET RECORDED AT A SEISMOGRAPH STATION
WHAT ARE SURFACE WAVES?
SEISMIC WAVES CAN BE GENERATED THROUGH EARTHQUAKES ON THE OCEAN FLOOR WHICH CAN CAUSE THESE
WHAT IS A TSUNAMI?
Earthquakes: vibrations through earth’s crust – Occur when rocks under stress slip or shift along a fault Normally, rocks are pressed together tightly.
Chapter 8 Earthquakes and Earth’s Interior. Section 8.2 Measuring Earthquakes.
EARTHQUAKES. Earthquakes & Plate Tectonics It is a vibration in the crust due to the release of stress Causes a shift in the rocks along a fault or plate.
Earthquakes Nelsons Class Earthquakes An earthquake is the shaking and vibrating of the earth caused by large and sudden releases of energy that.
Earthquakes Chapter 19. Earthquakes Natural vibrations of the ground caused by strain along faults in Earth’s crust Faults: the fracture or system of.
EARTHQUAKES. What are Earthquakes? The shaking or trembling of the earth/ground caused by the sudden release of energy Usually associated with faulting.

CH 8 Earthquakes Produced by the rapid release of elastic energy in rock causing vibrations Elastic Rebound Theory = the rock springs back into it original.
Chapter 8 Earthquakes and Earths Interior. What is an earthquake? An earthquake is the vibration of Earth produced by the rapid release of energy. –Example:
Chapter 9: Earthquakes 9.1: Earthquakes occur along faults 9.2: Earthquakes release energy 9.3: Earthquake damage can be reduced.
Earthquakes, Volcanoes, and Tsunamis. Earthquakes Fault: a break in the Earths crust. Blocks of the crust slide past each other along fault lines. When.

6 Chapter 6 Earthquakes and Earth s Interior. Earthquakes 6.1 What Is an Earthquake? Focus is the point within Earth where the earthquake starts. Epicenter.
Measuring Earthquakes How are earthquakes measured?
Chapter 15 EARTHQUAKES! BFRB Pages Earthquake causes An earthquake is the shaking of the Earth’s crust caused by a release of energy The movement.
Changes to Earth’s Surface Chapter 6. Prior Knowledge What are the layers of the Earth? What are the layers of the Earth? What causes Earth’s surface.
CST Review Standard 3 Plate Tectonics operating over geologic time has changed the patterns of land, sea, and mountains on Earths surface. a.Know the features.
Earthquakes Liz LaRosa 2009http://www.middleschoolscience.com for my 5 th grade science class 2009.
EARTHQUAKES MOTHER NATURES RUMBLINGS. What is that force? Earthquake – a vibration of the solid earth produced by the very rapid release of energy Earthquake.
8.6.2 Waves Explain how seismic waves provide scientists with information about the structure of Earth's interior.
