20080208721 | Computer System and Method for Determining an Earthquake Damage Index - In a computer system and a computer-implemented method for determining a damage index indicative of damage caused by an earthquake to a portfolio of objects associated with a geographical area, local portfolio replacement value indices are stored assigned to object or grid coordinates of the geographical area. For each coordinate having a local portfolio replacement value index assigned to it, a local damage index is calculated from location, depth, and magnitude data related to the earthquake and from the local portfolio replacement value index, using local vulnerability and attenuation parameters. The damage index is calculated by aggregating the local damage indices for the grid coordinates. For any size of the geographical area and for any resolution of the grid, a damage index reflecting the geographical distribution of the portfolio objects can be determined, without need for a network of seismological measurement stations distributed in the geographical area. | 08-28-2008 |

20110196810 | COMPUTER SYSTEM METHOD FOR DETERMINING AN EARTHQUAKE IMPACT - For determining an impact index which indicates the image or damage caused by an earthquake to a portfolio, an equation is stored for calculating a local earthquake intensity for a geographical location. The portfolio includes geographical locations and individual weighting factors assigned to the geographical locations. Furthermore, for the geographical locations stored are one or more impact ratio tables including impact ratios for different earthquake intensity levels. The impact index is calculated for the geographical locations by determining in each case the impact ratio for the local intensity at the respective geographical location, and adding up the impact ratios weighted in each case by the weighting factor assigned to the respective geographical location. An impact index that reflects the geographical distribution of the portfolio can be determined, without the need for a network of seismological measurement stations associated with the geographical locations. | 08-11-2011 |
20110270793 | EARTHQUAKE DAMAGE PREDICTION AND PREVENTION SYSTEM AND METHOD THEREOF - An earthquake damage prediction and prevention system for determining an impact or damage caused by an earthquake to objects associated with different geographical locations. A central unit with a filter module selects and collects earthquake related data of a plurality of network units. At least one impact ratio table is stored with a first data structure for storing geographical and/or topographical data coordinates of the different geographical locations. The geometric distances of the geographical locations from a hypocenter/epicenter are generated by an intensity calculation module with a coordinates processor. Local intensity values based upon the generated geometric distances and a given earthquake magnitude of a stored parameterization including variable weight parameters are generated by a propagation calculation unit of the intensity calculation module, whereas the generated geometric distances are stored assigned to the corresponding geographical locations by a second data structure of the impact ratio table. At least one of the variable weight parameters and/or at least one impact ratio for different earthquake intensity levels indicative of the impact or damage caused by an earthquake to the object and/or at least one object parameter defining earthquake exposed structures of the object are received from a plurality of users. By an index calculation module the impact index for the geographical locations is generated by determining in each case from the impact ratio table the impact ratio for the local intensity at the respective geographical location, and the impact ratios are added up weighted in each case by the weighting factor assigned to the respective geographical location. | 11-03-2011 |
