Seven years after the devastating storm of Hurricane Katrina, the residents of the southeast United States are being displaced yet again by Hurricane Isaac. Many have flocked to shelters because of the massive flooding – it is estimated that 1 in 4 people in Louisiana will feel the effects of Isaac.

This time around, social media is playing a much larger part in spreading the news and offering outlets to donate to offset the costs of damage as a result of Isaac. USA Today just published an article entitled, “Disaster-relief groups try tweets, apps to spread the news.”

Red Cross has a Hurricane Isaac app for iPhone. the Federal Emergency Management Agency has a Facebook page urging storm victims to relay their experiences. The White House is getting firsthand accounts from Twitter users and bloggers.

Social media’s reach may be far greater than Isaac’s storm front.

Tens of thousands of relief workers, government officials, hospitals and residents looking for up-to-date information are using social media to stay abreast of what’s happening with Isaac. It’s another example of just how deeply social-media outlets have embedded themselves in today’s world — particularly when a potential tragedy strikes.

A role model and leader for residents of Louisiana, Quarterback for the New Orleans Saints Drew Brees tweets about the storm:

Oil giant BP will graciously donate $1 million for Isaac relief. The President and other celebrities are using social media to raise more funds for the Red Cross and Salvation Army relief funds.

If you’d like to make a donation please visit the American Red Cross Disaster Relief donation page or Text REDCROSS to 90999 to give $10 to American Red Cross Disaster Relief, which helps people affected by disasters such as hurricanes, floods, earthquakes, wildfires and tornadoes.
