WORKSHEET: WORLD WIDE EARTHQUAKES AND SEISMICITY (Part One)

Objectives:
a. Plot current earthquake location data on a world map.
b. Observe relationships between earthquake locations and plate boundaries.

Instructions:
1. Use the following Web site to find the location of the most recent earthquakes worldwide:
http://earthquake.usgs.gov/recenteqsww/Quakes/quakes_big.html
(Use the above Web site for Part One and Part Two)

2. Record the data for the 10 most recent earthquakes on the chart below. Begin with the most recent earthquake. If there are several earthquakes in the same general location, record the location only once on the chart below. This will allow you to show a greater variety of earthquake events.

Date / Time
yy/mm/dd hh/mm/ss / Latitude / Longitude / Depth / Magnitude / Comment

3. Locate and label each of the above earthquake epicenters in red or other bright color on a world map.

WORKSHEET: WORLD WIDE EARTHQUAKES AND SEISMICITY (Part Two)

At the same USGS Web site, click on each of the locations listed in the Part One chart to see the details of each earthquake epicenter.
Complete the chart below.
A map shows the epicenter and the geography of the surrounding region. A small globe shows the location of the earthquake. For a map showing earthquake epicenters throughout the region for the last 20 years, choose Historical Seismicity. The depth of each earthquake is plotted in color. Use this information to help you record the depth (shallow, intermediate, or deep) for past earthquakes in the region. Plate boundaries are plotted in yellow when they are present.
You need to refer to a map of tectonic plates to help determine the kind of plate boundary that is present and the name of the plates involved. Use Tarbuck textbook, pgs 188-189. Geographic features include mountains (name them if possible), ocean trenches, and anything else that you observe on the maps.
Provide the following information for each of the earthquakes in Part One:

Location
(Nearest City) / Plate Boundary
(Yes/No) / Type of Boundary / Depth of Past
Earthquakes / Geographic
