Question

earthquake danger zones
do you ever wonder if you are in danger of experiencing an earthquake? the u.s. geological survey (usgs) has identified five regions, or zones, that tell the strengths of earthquakes that can be expected. the zones range from 0 to 4, with 0 being the safest areas and 4 being the most dangerous.
directions
a. lightly color each box in the key below the following colors: zone 0 - yellow, zone 1 - green, zone 2 - blue, zone 3 - orange, zone 4 - red.
b. then color the earthquake zones on the map according to your key.
c. finally, use the map to help you answer the questions that follow.
united states map
(there is a map of the united states including alaska and hawaii here, with different patterns representing different earthquake zones, and a zones key below: zone 4 (a pattern), zone 3 (a pattern), zone 2 (a pattern), zone 1 (a pattern), zone 0 (a pattern))

1. zone 0 represents the ______ areas and zone 4 represents the most ______.
2. name the four states that will probably not experience an earthquake because the entire state is in zone 0.

______, ____, ____, ______

1. name the three states that experience earthquakes from zone 1, zone 2, zone 3, and zone 4?

______, ____, ______

1. washington state lies in what 2 zones? ______, ______
2. california will experience earthquakes from which zones? ______, ______
3. are the west or east coast states more at risk for strong earthquakes? ________

why do you think so? _________________________________________
___________________________________________________________

1. is georgia at risk for an earthquake? ______ in which 3 zones does georgia fall? , and __
2. why do you think hawaii would be in zone 3? ________

Explanation:

1. Fills in blanks using the initial text's definitions of the zones.
2. Identifies Zone 0 states from the map (the empty, unshaded states: North Dakota, South Dakota, Nebraska, Minnesota).
3. Identifies states that span all 4 shaded zone patterns: Alaska, California, Nevada.
4. Matches Washington State's map shading to the key.
5. Matches California's map shading to the key.
6. Compares west vs east coast zone shading; west has more high-danger (Zone 4/3) areas.
7. Checks Georgia's map shading to confirm risk and its zones.
8. Links Hawaii's volcanic/tectonic activity to earthquake risk.

Answer:

1. safest; dangerous
2. North Dakota, South Dakota, Nebraska, Minnesota
3. Alaska, California, Nevada
4. Zone 3, Zone 4
5. Zone 3, Zone 4
6. West Coast; The west coast has large areas in Zone 4 (most dangerous) and Zone 3, while the east coast has mostly lower-risk zones.
7. Yes; Zone 1, Zone 2, Zone 3
8. Hawaii has active volcanoes and is located on a tectonic hot spot, which causes frequent seismic activity that places it in Zone 3.
