Typical concrete and cinder block buildings can survive strong winds but are vulnerable to damage or collapse when the ground shakes. Poor building practices can also play a role.
The 2010 quake hit closer to densely populated Port-au-Prince and caused widespread destruction. Haiti’s government put the death toll at more than 300,000, while a report commissioned by the U.S. government placed it between 46,000 and 85,000.
“I think it’s important to recognize that there’s no such thing as a natural disaster,” said Wendy Bohon, a geologist with Incorporated Research Institutions for Seismology. “What you have is a natural hazard that overlaps with a vulnerable system.”
WHAT DOES THE FUTURE HOLD?
Geologists say they cannot predict the next earthquake.
“But we do know that earthquakes like this can cause similar-sized earthquakes on the next portion of the fault,” said Hayes of USGS. “And it’s quite a significant hazard in places that don’t have the construction practices to withstand the shaking.”
Construction of more earthquake-resistant buildings remains a challenge in Haiti, which is the poorest nation in the Western Hemisphere.
Before Saturday’s quake, Haiti was still recovering from the 2010 earthquake as well as Hurricane Matthew in 2016. Its president was assassinated last month, sending the country into political chaos.
