Google, Yahoo and Bing, among many others, are offering cash donations and resources to assist with disaster relief in Haiti. Here’s our earlier coverage of  online resources. You can also find images of post Earthquake Haiti from Bing Maps and Google.

Google has a full-blown disaster relief center with a wide range of updates, free Google Voice calls and places to donate money. There’s also a “person finder” microsite to enable family members or friends to request information and others with knowledge of whereabouts or details to provide it.

Mobile/SMS donations have now surpassed $20 million. Here are some of the ways to donate via text message:

• Text the word “Quake” to 20222 to donate $10 On behalf of The Clinton Bush Haiti Fund
• Text the word “Oxfam” to 25383 to donate $10 On behalf of Oxfam America, Inc. On behalf of Cooperative for Assistance and Relief Everywhere, Inc. (CARE)
