Task: Question Answering
Input (English): passage: The island of Hispaniola, shared by Haiti and the Dominican Republic, is seismically active and has a history of destructive earthquakes. During Haiti's time as a French colony, earthquakes were recorded by French historian Moreau de Saint-Méry (1750--1819). He described damage done by an earthquake in 1751, writing that ``only one masonry building had not collapsed'' in Port-au-Prince; he also wrote that the ``whole city collapsed'' in the 1770 Port-au-Prince earthquake. Cap-Haïtien, other towns in the north of Haiti and the Dominican Republic, and the Sans-Souci Palace were destroyed during an earthquake on 7 May 1842. A magnitude 8.0 earthquake struck the Dominican Republic and shook Haiti on 4 August 1946, producing a tsunami that killed 1,790 people and injured many others.
 question: was there a tsunami after the haiti earthquake?
Output (English): Yes
