EARTHQUAKES Shake, Rattle and Roll!

earthquake: shaking and trembling that results from sudden movement of part of the Earth’s crust Caused by release of energy (lithospheric plates)

1. What do seismologists use to determine when an earthquake started? A seismogram 2. How is the intensity of an earthquake determined? By the amount.

Earthquakes. Causes of Earthquakes An earthquake is a shaking of Earth’s crust caused by a release of energy Mostly caused by the strain that builds.

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?

DAILY DOUBLE!!!! THIS CIRCULAR AREA INCLUDES THE WEST COASTS OF NORTH & SOUTH AMERICA, EASTERN ASIA, & THE WESTERN PACIFIC ISLANDS

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?

ARE NEEDED TO LOCATE THE EPICENTER OF AN EARTHQUAKE AT LEAST THREE OF THESE ARE NEEDED TO LOCATE THE EPICENTER OF AN EARTHQUAKE

LOCATE THE EPICENTER OF HOW MANY SEISMOGRAPH STATIONS ARE NEEDED TO LOCATE THE EPICENTER OF AN EARTHQUAKE?

IS USED TO DETERMINE THE 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?

VALUES FOR THE MAGNITUDE 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 LITHOSPHERE, OR ANY SOLID 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 RECORDED AT A SEISMOGRAPH 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?
