Nevertheless, this earthquake also generated a tsunami which caused the death of at least 7 people. It caused flooding and damage both within the bay of Port Prince and the southern coast near Jacmel. The tsunami was also observed at the DART buoy in the Caribbean as well as the tide gauge in Port San Andrés in the Dominican Republic. At the tide gauge, located in a very protected harbor just east of Santo Domingo, the maximum peak to trough measurement of the tsunami was 12 cm. Local Tsunami Watches were issued by the PTWC for Haiti, Cuba, Bahamas and Dominican Republic.
