Student Work

• Download geo-refrenced earthquake files from USGS
• Using Arcview, Create a map of the world showing
  all earthquakes in the last 2 years.
• With boundaries indicated by seismic activity,
  label the Earths major tectonic Plates

Student Work

• In Arcview, format the earthquake data to show
  earthquake magnitude.
• Explore the world map and find a location at risk
  for high magnitude earthquakes
• Create a hazard map showing risk

This is an area of high magnitude earthquakes.
You can tell because of all of the dark green
dots.

dots earthquakes darker Color higher magnitude
One place that would be risky to live is Central
America, because there has been many earthquakes
of high magnitudes in the past two years. It is a
big tourist attraction though. In this picture
the Cocos plate is converging with the Caribbean
plate
26
Student Work

• Using your knowledge of Plate Tectonics, find an
  area where earthquake activity indicates active
  subduction.
• Within Arcview, format earthquake data to show
  hypocentral depth and create a map to show plate
  subduction.

This diagram shows how the Indo-Australian plate
is subducting beneath the Eurasian plate based on
depth
Brighter colored dots represent Earthquakes
higher on the earths Surface.
Kamron Milani - 03.08.04
Each red monochromatic dot represents an
earthquake that occurred within the years 2003
and 2005
We can prove that the Indo-Australian Plate is
subducting beneath the Eurasian Plate because the
higher earthquakes would Occur at the top of the
subduction and Gradually get deeper and deeper
Darker colored dots represent Earthquakes deeper
into the earth
