The Chilean Tsunami
Name:
The 1960 Chilean earthquake measured 9.5 on the Richter Scale. This is the largest earthquake
ever recorded and caused a massive tsunami.
Use the map at this site (http://nctr.pmel.noaa.gov/chile20100227/T1960_1-annotated.png) to find
out how many hours the tsunami took to reach:
New Zealand
hrs
Papua New Guinea
hrs
Tasmania
hrs
Hawaii
hrs
Australian mainland
hrs
Western Australia
hrs
Taiwan
hrs
Canada
hrs
Aleutian Islands
hrs
(Hint: The numbers on the lines of the map represent hours.)
Select one of these places and research to find out what effect/s the tsunami had.

Tsunami Mapping
Name:
One way to complete an ‘overlay map’ is to use tracing paper.
Place the tracing paper over your world map and mark in the border to align the two pieces of
paper. You do not need to trace any markings from the underneath map - you can see them.
The finished overlay map will have an informative title and a legend.
Steps:
ƒƒ
ƒƒ
ƒƒ
O n the overlay, clearly mark the major tectonic plates and earthquake zones.
ƒƒ
ƒƒ
ƒƒ
O n the overlay clearly show the major active volcanoes.
Clearly write in the name of each major tectonic plate.
In the legend provide the symbol for the plate boundary and the symbol for the earthquake
zones.
Clearly label the ‘Ring of Fire’.
In the legend provide a symbol for the active volcanoes.
Carefully study the two maps. Circle the correct option in each following statement:
a. Most tsunami do / do not occur around the Pacific Ocean.
b. T here appears to be a very strong / very weak match between the distribution of earthquakes
and the location of tectonic plate boundaries.
c. T here appears to be a very strong / very weak match between the distribution of volcanoes
and the location of tectonic plate boundaries.
d. T here appears to be a very strong / very weak match between the distribution of earthquakes
and the distribution of tsunami.

Now answer the following questions:
1. Why are subduction zones (where tectonic plates collide) likely to be the origin of tsunami? Use
a diagram to explain.
2. Which parts of Australia are at risk from tsunami and why?

If you are given a tsunami warning you should follow instructions and move to higher ground.

If you:
A lways listen to lifeguards, Surf Lifesavers and emergency workers.
If a tsunami warning is given, DO NOT stay to watch. DO NOT go back to the water until you
are told it is safe.
• h ear a loud roaring sound louder than the normal ocean, or
• see the water move out to sea more than the normal tide, or feel an earthquake near the
beach a tsunami might be coming, so move quickly to higher ground.
