A logical extension here would be some kind of app where you could specify certain events happening in say a certain radius of you depending on the event or just events in general and get a real time window open if something that you have specified has happened and starts updating. Wouldn't even have to know about an even initially then to search, even though this isn't an issue with an earthquake you feel yourself.
