Group: Brooke, Kristin, Daniel, Emily

Observations:
The majority of earthquakes occur at 0-33km deep.
The majority of the earthquakes occur along the plate boundaries.
The deepest earthquakes (300-700km) usually occur in deep water. Exception: along the east side of the Andes Mountain in South America.
The earthquakes along the ocean tend to be more shallow than those that follow the boundaries on the land.
Earthquakes occurring at 70-300 km and 33-70 km usually occur along coastal areas.
Most earthquakes occur between 60 degrees North or South of the equator.
No earthquakes are reported in Antarctica, Greenland, and certain parts of Canada.
