Carrefour Haiti Earthquake M7.0
January 12, 2010 | USGS Earthquake Hazards Program

USGS reports that a magnitude 7.0 earthquake occurred in Haiti at about 4:53 PM local time. It occurred at a depth of only 10 kilometers, resulting in very strong shaking. Their estimated intensity was up to IX as shown in the map below. The cities of Carrefour, Port-au-Prince and Delmas all have significant populations and are in areas where estimated intensities were VIII and IX.

The USGS comparative: “Overall, the population in this region resides in structures that are vulnerable to earthquake shaking, though some resistant structures exist. On June 24, 1984 (UTC), a magnitude 6.7 earthquake 329 km East of this one struck the Dominican Republic, with estimated population exposures of 320,000 at intensity VII and 2,964,000 at intensity VI, resulting in an estimated 5 fatalities. Recent earthquakes in this area have caused landslides that may have contributed to losses.”
