Lab Period: ____
Problems:
1. What is the pattern of earthquake distribution over the Earth?
2. How do the locations of mountain chains and volcanoes compare to earthquake locations?
Objectives: After you have completed this investigation you should be able to:
1. Search the Internet for recent earthquakes.
2. Identify regions of high seismic activity on a world map.
3. Search the Internet for locations of volcanoes.
4. Identify regions of high volcanic activity on a world map.
5. Determine if areas experiencing frequent earthquakes are associated with other unusual crustal
features or crustal activity.
Procedures:
1. Go to the following website: http://neic.usgs.gov/neis/qed/
a. Choose 30 Days M2.5+ in drop down menu top left.
b. Using the world map, shade in the regions that have experienced earthquakes in the last 30
days with a GREEN pencil. It is not necessary to mark where every earthquake has
occurred just the general regions. Be sure to include oceanic earthquakes also.
2. Go to the following website:
http://earth.rice.edu/mtpe/geo/geosphere/hot/volcanoes/volcanoes_b2.html
a. Shade the regions with volcanic activity with a RED pencil.
3. Go to the following website:

a. Shade the oceanic mountain belts with a BLUE pencil. (Shown in grey in the oceans)

2. Describe the relationship between the locations of the volcanoes, mountain ranges, and regions
of frequent earthquakes?

3. What would cause earthquakes be common in mountain ranges?
____________________________________________________________________________
4. Name and describe the process that is occurring in the regions where earthquakes and volcanic
mountain chains are in the same place. Specifically around the Pacific Ocean.

5. Suppose you had a choice of going to one of the following locations: Anchorage, Alaska;
Istanbul, Turkey; Allegany, NY; Stockholm, Sweden or San Francisco, California.
a. At which location(s) would you most likely experience frequent earthquakes?
___________________________________________________________________
b. At which locations(s) would you be least likely to experience any earthquakes at all?
___________________________________________________________________
● Anchorage, Alaska,
● Stockholm, Sweden
● Allegany, New York
San Francisco●,
Earthquakes = Green
● Istanbul, Turkey
Volcanoes = Red
Oceanic Mountain Belts = Blue
Continental Mountain Belts = Orange
