Bloomberg described the earthquake and aftermath as "sad news" and said people looking to help should give to the Mayor's Fund To Advance New York City.
Jean Wallace with the Mayor's Fund told HuffPost people can donate via credit card by calling (212) 788-7794, or by sending a check to:
The Mayors Fund NYC
253 Broadway 8th floor
New York, NY 10007
Checks to the Mayor's Fund should include instructions to use the donation for earthquake relief efforts.
