The only data required for Time Dependent Seismic Hazard (TDSH - selected area mode), application is a catalog containing seismic events ('_catalog.mat' is appended in the filenames contain such catalogs). The User enters his/hers personal workspace and clicks on a seismic events catalog, that is already uploaded (see "AH Episodes" chapter). For using a selected catalog for TDSH, the User shall click on the "Actions" tab and then select consecutively, "USE IN APPLICATION" and "Hazard in selected area", as highlighted in Figure 1.

Once the service has been selected the User is requested to select options and fulfill some fields with parameter values needed for the TDSH analysis (see the following Figures). These parameters are:

...

Magnitude distribution estimation method: Four different methods are available in the IS-EPOS platform: The Unbounded Gutenberg-Richter, the Upper-bounded Gutenberg-Richter, the unbounded non-parametric and the Upper-bounded non parametric estimations. To select one of the aforementioned methods of analysis, the User has to click on the arrow in the respective box.

Time window Window time step (days): In this field the User selects the time window step, i.e. the number of days between the starting dates of subsequent datasets (see Figure 4 for details).

...

Method of creating windows: Two options are available at this field after clicking on the small arrow of the tab  (see "Time window Size" below for details).

Time window Window size: Size (span) of the windows containing data for the analysis. "TIMEconstant time period" and "EVENTSconstant event number". If "TIME" time-mode is selected, the given value corresponds to the duration of each dataset, in days. If "EVENTS" events-mode is selected instead, the given value corresponds to the number of events that each dataset contains (see Figure 4 for details).
