Aug. 23 (UPI) -- On this date in history:
In 1990, East and West Germany announced they would reunite on Oct. 3.
In 2005, the tropical depression that would eventually become Hurricane Katrina formed over the Bahamas. Two days later, the storm strengthened into a hurricane shortly before making landfall in Florida. On Aug. 29, the Category 5 storm came ashore in Louisiana, killing more than 1,200 people and causing more than $100 billion in damage.
In 2010, rescue workers at a caved-in gold and copper mine in northern Chile made radio contact with 33 men trapped nearly 2,300 feet underground for 17 days who had found refuge in a small emergency shelter that had water and ventilation. In an unrelenting effort, all hands were rescued two months later.
In 2011, a 5.8 magnitude earthquake, unusually strong for the eastern United States, rattled Washington and Virginia with shockwaves as far north as Canada. The quake was the strongest to hit Virginia in more than a century, briefly causing a power shutdown at a nuclear plant. The Washington Monument and National Cathedral in Washington were damaged by the quake.
In 2014, the NBA's Cleveland Cavaliers, who reacquired four-time league MVP Lebron James in June, added Kevin Love, another big star, to their lineup. Love left the Minnesota Timberwolves and joined the Cavs in a three-team deal that also involved the Philadelphia 76ers.
