Here is a terrific review of mobile phone applications that range from first aid and CPR, to survival guides during earthquakes. Here I should also note that my pal Chuck Valen pointed out the earthquake application from the American Red Cross to me a few months ago -- it's awesome!
The Pacific Northwest Economic Region (PNWER) has also been developing a phone app, called First To See , which is still in test mode; and for which there will be additional enhancements. Though first responders will be trained on the app, there's no reason that regular folk might not also find it useful. Take a look and see what you think.
