The data in the Sandy collection comes from the Northeast, primarily the area around Manhattan. It runs from October 25, when Hurricane sandy was in the news and states were preparing for its onslaught, through November 3 (though data from this late period are relatively sparse.) As such, the tweets in the Sandy data should cover both disaster preparation and some reports of cleanup in the aftermath of the affair.
