I've discussed this many times both here on HN and elsewhere so I won't go over what I've previously except to say this story further supports my earlier arguments/points. What's relevant here is how this information can be put into use effectively to provide some degree of early warning of earthquakes. As an idea I've suggested the Amateur Radio Service could set up a network to monitor changes in the ionosphere. Due to the many diffetent/diverse locations of Amateur stations triangulating the location of a pending earthquake would be possible. In the absence of a more formal monitoring system using the Amateur service would seem the quickest way of starting a worldwide monitoring network. If nothing else it'd be a cheap way of doing a feasibility study.
