ABSTRACT

In the aftermath of the magnitude 7.0 earthquake that devastated much of southern Haiti on 12 January 2010, the Geological Survey of Canada (GSC) along with the U.S. Geological Survey (USGS) and Géoazur installed seismograph and strong‐motion stations in Haiti. Prior to the earthquake, there had been almost no instrumental monitoring of Haiti’s earthquakes. The three GSC stations consisting of collocated weak‐ and strong‐motion instruments comprised the first real‐time seismic network in Haiti. These stations were initially used primarily for aftershock monitoring but also contributed data to subsequent research projects as well as to the Caribbean Tsunami Warning System. They are still operational albeit with varying degrees of reliability. In this article, we discuss the station deployment, data access, and some of the science outputs from their data. In particular, aftershock locations, site response, velocity models, and attenuation are discussed. Combined with the data from the other deployments, they contributed to a much better understanding of the seismicity and seismotectonics of Haiti. Finally, in the years subsequent to 2010, Haiti has established its own network consisting of two seismograph and five accelerograph stations with real‐time data availability and three additional non‐real‐time strong‐motion stations all of which, combined with the establishment of the Unité Technique de Sismologie, have led to improved seismic monitoring.
