On Shaking Ground
By completing these activities, the learner will:
suggest process that can destroy buildings.
understand that earthquakes occur in some parts of the United States.
discern patterns of world-wide earthquake locations.
predict where earthquakes are most likely to occur.
practice procedures to follow should an earthquake occur.
the following pictures of buildings and other man-made things found on
the Internet. Suggest what you think might have happened to them:
Earthquakes occur in lots of different places. Look at some of the recent
around the world
of Earthquakes Recorded in the Last 14 Days
As you can see, most of the earthquakes
occuring in the United States are in the western
portion. This includes:
Although earthquakes are infrequent, there are also active regions in
and in the MississippiValley.
Maps on the Web
Earthquakes occur all over the world
Do you think that it is likely that an earthquake could occur where you

Current Western Regional Seismic Activity Map
What would an earthquake feel like? Can you pretend that there is an earthquake?
Draw a picture of the damage.
you do if there is an earthquake? Teach other students in your school
What would your school principal
do if there was an earthquake? What would you do if you were the principal?
What do you do after
an earthquake? Who helps people
after natural disasters?
Use Internet resources to find out information if a new
Plot the location of earthquakes
Students can plot the epicenters
on a large classroom map of the region to be studied. Students use pieces
of yarn attached to sliding hooks across the top and side of the map as
guides to the longitude and lattitude coordinates from the seismic data
taken from the interenet. The location of the quake is marked by a pin
sticker, or colored on the map.
After charting this data for a month use the map and analyze the data.
Examples of questions .
For International Earthquakes: Chart global
earthquakes once a week throughout the year. You need Internet earthquake
and a worldmap.
Count all the earthquakes in each state. Use the information to determine
number of earthquakes in the region. Also, which state has the most
earthquakes? Least earthquakes? How many earthquakes were in each state?
What is the difference in earthquakes between the state with the most and
the state with the least? Make a graph of the number of earthquakes in
each state over a 1 or 3 month period.
Sort earthquakes by Richter Scale Rating (sort by greater than magnitude
four and less than magnitude four)
Find the total of the number of eathquakes in each category. What is the
difference between them?
What earthquake had the greatest magnitude? Where was the location of the
Name a place that had many earthquakes.
Why do you think that place had so many earthquakes?
Name an area you predict will have an earthquake. Explain why you think
this is so.
After recording data for 5 months have students make general observations
about patterns they see developing on the classroom map. Have them explain
their reasoning for these observations.
