    	But, we can at least do things like send SMS Text messages to people
    when we get earthquake announcements. CISN and USGS do that now and we'll be
    generating SMS messages off our data at PubSub soon as well.
    
    	Another interesting application of cell phones to the problem of
    emergency info would be the "I am Alive" service that was discussed in
    http://www.ietf.org/internet-drafts/draft-baker-alert-system-00.txt .
    An overview of the "I am Alive" service can be found at:
    http://www.isoc.org/inet2000/cdproceedings/8l/8l_3.htm
    	While such a service might increase the amount of SMS traffic after
    a disaster, we might find that we could profitably trade off SMS traffic for
    voice links. My assumption is (I'm not a telephony expert) that SMS traffic
    is probably easier for the network to handle then a potentially long voice
    session. Convincing people to get in the habit of sending an SMS message to
    some "I am alive" service that could be queried over the Internet might
    reduce the number of people who try to make calls into impacted areas during
    emergencies and thus free up bandwidth for more important calls.
