The island of
Hispaniola,
shared by Haiti and the
Dominican Republic, is seismically active and has experienced
significantly destructive tremors in the past.
According to Jean Vogt in the article "A glimpse at the historical
seismology of the West Indies", "Widespread cracking and liquefaction
occurred in 1751 and 1770 in the wide Cul-de-Sac plain of Southern Haiti,"
and this liquefaction, in which layers of sediment in the earth's crust
shift and form a liquid-like substance that causes buildings, piers, and
other structures to shift and break, was present in the 2010 Haiti
earthquake as well.
