2 THE AREA WHERE SLIPPAGE FIRST OCCURS ALONG A FAULT

3 WHAT IS THE FOCUS?

4 A SERIES OF SMALL TREMORS FOLLOWING AN EARTHQUAKE

5 WHAT IS AN AFTERSHOCK OR MICROQUAKE?

6 90% OF CONTINENTAL EARTHQUAKES HAVE THIS KIND OF FOCUS WHICH ALSO CAUSES THE MOST DAMAGE

7 WHAT IS A SHALLOW FOCUS?

8 MOST QUAKES OCCUR NEAR THESE

9 WHAT IS A PLATE BOUNDARY?

10 ACCORDING TO THIS THEORY ACCUMULATED STRESS CAUSES ROCK TO DEFORM OR FRACTURE AND THEN SPRING BACK INTO THEIR ORIGINAL SHAPE CAUSING AN EARTHQUAKE

11 WHAT IS THE ELASTIC REBOUND THEORY?

12 A GROUP OF INTERCONNECTED FAULTS

13 WHAT IS A FAULT ZONE?

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

15 WHAT IS THE PACIFIC RING OF FIRE?

16 OCEANIC CRUST PULLS AWAY FROM BOTH SIDES OF THIS AREA

17 WHAT IS A MID-OCEAN RIDGE?

18 THIS FAULT EXTENDS ALONG MUCH OF THE LENGTH OF CALIFORNIA

19 WHAT IS THE SAN ANDREAS FAULT?

20 COMPRESSION, TENSION & SHEARING

21 WHAT ARE 3 TYPES OF STRESS FORCES ACTING ON ROCK?

22 THIS TOOL RECORDS ENERGY RELEASED BY AN EARTHQUAKE

23 WHAT IS A SEISMOGRAPH?

24 THIS IS A SCIENTIST WHO STUDIES EARTHQUAKES

25 WHAT IS A SEISMOLOGIST?

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

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

28 THIS KIND OF GRAPH IS USED TO DETERMINE THE EPICENTER OF AN EARTHQUAKE

29 WHAT IS A DISTANCE TIME GRAPH?

30 TO DETERMINE HOW FAR AWAY FROM A SEISMOGRAPH STATION AN EARTHQUAKE OCCURRED, SCIENTISTS PLOT THE DIFFERENCE BETWEEN THESE 2 WAVES

31 WHAT ARE P & S WAVES?

32 THIS IS AN APPROXIMATE MEASURE OF HOW MUCH ENERGY THE EARTHQUAKE RELEASES

33 WHAT IS THE MAGNITUDE?

34 A MAGNITUDE OF 2.5 OR LESS, WHICH CANNOT BE FELT BY PEOPLE

35 WHAT IS A MICROQUAKE?

36 DAILY DOUBLE!!!!!!!!!! THIS SCALE PROVIDES VALUES FOR THE MAGNITUDE OF AN EARTHQUAKE

37 WHAT IS THE RICHTER SCALE?

38 THESE WAVES CAUSE THE MOST DAMAGE

39 WHAT ARE SURFACE WAVES?

40 A 7 OR ABOVE ON THE RICHTER SCALE

41 WHAT IS A MAJOR EARTHQUAKE?

42 THESE WAVES ARRIVE FIRST AT A SEISMOGRAPH STATION

43 WHAT ARE PRIMARY, OR P WAVES?

44 THESE WAVES CAN ONLY TRAVEL THROUGH THE LITHOSPHERE, OR ANY SOLID

45 WHAT ARE SECONDARY WAVES, OR S WAVES?

46 THESE ARE COMPRESSION SEISMIC WAVES

47 WHAT ARE P WAVES?

48 THESE WAVES ARE THE LAST TO GET RECORDED AT A SEISMOGRAPH STATION

49 WHAT ARE SURFACE WAVES?

50 SEISMIC WAVES CAN BE GENERATED THROUGH EARTHQUAKES ON THE OCEAN FLOOR WHICH CAN CAUSE THESE

51 WHAT IS A TSUNAMI?
