Patent ID: 8055563

Claim:
A computerized method of offering for purchase, positions predicting a future hurricane landstrike resulting from a substantially continuous ongoing natural process culminating in a future hurricane landstrike, comprising: providing a computer graphical user interface having an output for a display that has first and second regions; providing a database containing 1) a map of geographical areas corresponding to the positions to be offered for purchase, the geographical areas being at least one of the coastal and the inland type; 2) strike probabilities of future hurricane landstrikes for the geographical areas; 3) offer prices for purchasing positions predicting future hurricane landstrikes in respective geographical areas, that are based at least in part on respective strike probabilities; 4) current level of severity of the continuous ongoing natural process; and 5) the level of severity of the future hurricane landstrike; displaying the map in the first region of the graphical user interface with user selectable items corresponding to the geographical areas of the map; during the substantially continuous ongoing natural process, electronically obtaining updated data including the location and level of severity of the continuous ongoing natural process culminating in a future hurricane landstrike so as to provide at least part of the basis for electronic calculations of damage probabilities of a future hurricane landstrike for the geographical areas; in response to a user selecting a user selectable item and thereby indicating a geographical area for selection, displaying in the second region of the graphical user interface, an offer price, electronically updated in substantially real time so as to be based at least in part on an updated damage probability, for purchasing a position predicting the location and level of severity of a future hurricane landstrike in the indicated geographical area; and providing a payout value for users successfully predicting the location and level of severity of a hurricane landstrike resulting from the substantially continuous ongoing natural process.
