  • Coordinates Transformation

This Application is performed in order to transform the epicentral loation of the seismic events to a selected Cartesian Coordinate System (Note that epicentral location data available in IS-EPOS is given in geographical coordinates). The available types of coordinate systems are shown in Figure 7. Once the User makes the selection and clicks on the "Run" button, a new catalog is created, which contains all the data previously available in the original catalog, plus the seismic events epicentral location in the selected Cartesian system. The new catalog is stored in the system and is available for any further processing. In addition the system provides all the information and services that are valid for the original catalogs (see AH Episodes Chapter, for details).

  • Magnitude Conversion

Magnitude Conversion is a service used for establishing linear relationships between different magnitude scales, which can be later used for conversion of magnitudes from one scale to another. The input file is the seismic catalog.
