Two Earthquakes in Two Months:
Comparing the Quakes in Haiti (海地) and Chile (智利)
Overview (概要) How do the earthquakes in Chile and Haiti compare? Here, students perform a gallery
walk to learn more about the earthquakes from a specific point, and then do a specific research and
presentation project or response activity. Finally, they seek answers to their unanswered questions.
Materials Print copies of photographs, charts, documents and other visuals to display, as described
below; computer(s) with Internet access (optional), research materials, handouts.
Warm-up Choose and prepare a "gallery" of photographs, graphics, news reports and other materials to
display around the room to enable students to consider the 2010 earthquake in Chile.
Depending on course program, choose materials for the gallery that provide a window on the two quakes,
through one of the following specific points, or the focus of your choice:
Earthquakes through History Putting the 2010 Chilean and Haitian quakes into historical view related to
other earthquakes, including the 1960 Chilean quake and the 2004 Asian earthquake and tsunami.
Rescue and Aid Considering domestic and international response to the disasters by militaries, governments
and aid organizations, including rescue and recovery as well as efforts to provide food, water, health care and
shelter to those affected.
Related The article Underwater Plate Cuts '400 Mile Gash compares several earthquakes:
Mr. Lin figured that the quake on Saturday was 250 to 350 times more powerful than the Haitian quake.
But Paul Caruso noted that at least on land, the effects of the Chilean tremor (震动) might not be as bad.
For one thing, he said, the quality of building construction is generally better in Chile than in Haiti. And the fact
that the quake occurred offshore should also help limit the destruction. In Haiti, the rupture (断裂) occurred
only a few miles from the capital, Port-au-Prince. The rupture on Saturday was centered about 60 miles from
the nearest town, Chillan, and 70 miles from the country's second-largest city, Concepcion.
Read the article using the following questions.
