Correction—The caption that accompanies the Port-au-Prince, Haiti, damage assessment map on page 18 of the Spring 2010 issue of ArcNews dated the principal earthquake incorrectly. The caption should have read, ". . . within days of the January 2010 earthquake." This was corrected online as soon as it was called to our attention. Esri sincerely regrets any confusion or inconvenience this error may have caused.
