2021-08-14, M7.2, Haiti

At 12:29:09 GMT on the 14th August 2021 a magnitude 7.2 earthquake occurred about 125 km west of the Haitian capital Port-au-Prince, see map below. Extensive damage to buildings have been reported and it is feared that a large number of people died or have been injured. Previously, on the 12th January 2010 an M 7.0 earthquake struck in the same region of Haiti, about 75 km east from the 14th August 2021 event. According to the USGS “the 2010 earthquake caused substantial damage in the city of Port-au-Prince and the surrounding regions where damage from the earthquake and subsequent cascading hazards caused over 200,000 fatalities.”

The event was recorded by seismic stations worldwide, including stations in the Irish National Seismic Network (INSN) (see figure below). The first seismic waves originating from the Haiti earthquake arrived ~10 minutes after the event origin. However, another large M7.0 earthquake occurred about 30 minutes before the Haiti earthquake on the Alaska peninsula. The seismic surface waves of the Alaska event dominate the first ~15 minutes of the seismograms shown below.
