Activity 1 Student Worksheet: Plot Current Earthquake Data
You will need either a small world map to plot the earthquakes individually or in a small group
OR a large world map to plot the earthquakes as a class. If you do not
have a map, you can download a map from the
National Geographic Xpeditions web site:
- Click on one of the web sites listed below to see all of the earthquakes that have occurred over the last few days which were larger than 2.5 on the Richter Scale. Note that in the first two columns you will see the time and date for each earthquake. Note that in the second two columns you will see the latitude and longitude coordinates for the epicenter of the earthquake.
- TEXT-BASED (Recommend)
USGS Earthquake Bulletin
NOTE: Magnitude Greater Than 2.5 Earthquakes
From Around the World
- IRIS List
of Earthquakes (last 30 days)
NOTE: a latitude of + corresponds to degrees
North and a latitude of - corresponds to degrees South
a longitude of + corresponds to degrees East and a longitude of -
corresponds to degrees West
- INTERACTIVE MAPS
- Use the latitude and longitude coordinates to plot a dot on your world map which represents the epicenter of the earthquake. For older students, use a blue star if the earthquake occurred near the surface (less than 100 km) and use a red star if it occurred deep (greater than 100 km) in the earth (you will see the depth measurements in the table.)
NOTE: You can use the links that appear in the last column of the table to assist you in finding the locations of the earthquakes if using the latitude and longitude coordinates is too difficult.
- Do this for a period of at least two (2) weeks.
