2 The direction seismic waves travel.

3 What is all directions?

4 The fastest of the seismic waves

5 What is a Primary wave?

6 Only travels through solids

7 What is secondary wave?

8 Measures and records seismic waves

9 What is a seismograph?

10 The point within the earth where the energy is first released.

11 What is the focus?

12 Expresses the intensity of an EQ

13 What is the mercalli scale?

14 Measures the amount of energy released during an EQ

15 What is the Richter scale?

16 Complete destruction

17 What is XII on the Mercalli scale?

18 Can be used to find distance from an epicenter if lag time is known

19 What is a travel time graph?

20 Zones of immobile rock along faults

21 What are seismic gaps?

22 Vibration of the earth’s crust

23 What is an EQ?

24 Most EQ happen here

25 What are on plate boundaries?

26 Two plates moving toward each other

27 What is a convergent boundary?

28 3 types of boundaries EQ occur

29 What is convergent, divergent, transform?

30 Theory used to explain EQ

31 What is the elastic rebound theory?

32 The minimum number of stations needed to find an epicenter

33 What is 3?

34 Body of water formed by diverging plates

35 What is the Red Sea?

36 Largest fault in CA

37 What is the San Andreas?

38 The 3 EQ zones

39 What are Pacific Ring of fire, Mtn belt, Mid. Atl. ridge?

40 Area around the Pacific Ocean noted for EQ and Volcanic activity

41 What is the Pacific Ring of Fire?

42 The safest part of the house in an EQ

43 What is a doorway?

44 Where you should not go if there is an EQ

45 What is outside?

46 Food, water, radio, flashlight, and batteries

47 What are things to keep in case of an EQ?

48 Water, gas and power

49 What are things to shut off after an EQ?

50 Person responsible for enlightening you about EQs

51 Who is Ms Wessel?
