Communications used in earthquakes

In Pakistan, February 28 2006. An earthquake hit Islamabad which killed many people. FM radio stations were set in the location of the disaster broadcasting messages websites, blogposts and other internet awarness, both synchronous and asynchronous communications were launched. In earthquakes creatinga website and adding pictures and videos to it is a must. Meaning if the person publishes a site he must tell what is happening and going on, post images so people can get a visual view of his situation.
