Sitting directly over a complex network of fault lines, Haiti is one of the most earthquake-prone nations on Earth. In 2021, the Nippes earthquake became the latest to devastate the country, and today, researchers are still piecing together the timeline of seismic events which unfolded during the earthquake. Through their research, Professor Jeremy Maurer and colleagues at Missouri University of Science and Technology have described how the Nippes earthquake originated, shifted, and ruptured a major fault line, triggering numerous ‘afterslip’ events in the following days.
