Why does Haiti so tend to have fatal earthquakes? Earthquakes have been causing huge damage in Haiti since at least the 18th century. The capital city has been destroyed twice in 19 years. The 21st century has been no more kind.
The Earth's outer shell is made up of tectonic plates (构造板块) that move. Haiti sits near the crossing of two tectonic plates that make up the Earth's outer shell. Earthquakes can occur when those plates move against each other and create friction (摩擦力).
Haiti is also overpopulated. Plus, many of its buildings are designed to resist hurricanes but not earthquakes. Those buildings can survive strong winds but are easy to fall down when the ground shakes. Poor building practices can also play a role.
“I think it's important to recognize that there's no such thing as a natural disaster,” said Wendy Bohon, a geologist. “What you have is a natural disaster that comes with a weak architecture system. We do know that earthquakes like this can cause huge damage because of the_fault,” said Wendy. “And it's quite a significant risk in places that don't have the construction practices to resist the shaking.”
Construction of more earthquake-resistant buildings remains a challenge in Haiti, which is the poorest nation in the Western Hemisphere. “While there have been some success stories of Haitians building more earthquake-resistant structures, the country has lacked a centralized effort to do so,” said Mark Schuller, a professor of anthropology and non-profit and NGO studies at Northern Illinois University. Haiti's government has become increasingly weak, while non-governmental organizations only focus on their own projects.
“There is technical knowledge in Haiti. There are trained architects. There are city planners. That's not the problem,” Schuller said. “The problem is a lack of funding for coordination (协调), and lack of political will from donors to organizations providing aid.”
