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 goes to his/hers personal workspace and clicks on a seismic events catalog, that is already uploaded (see section ..... eg data handling). 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 shown in figure 1.
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:
Using seismic catalog: A catalog has been already uploaded since the previous step, however, the User has the chance to select a different dataset, either from another episode or the any dataset after performing some processing/ filtering.
Select Magnitude column: The user may click on the small arrow in the respective tab in order to chose among different magnitude scales, in the cases where they are available (e.g. ML, Mw, etc).
Select Area: This is an interactive option providing to the User the possibility to select data, spatially constrained by a predefined shape (numbers 1-5 in figure 2):
1) No draw option.
2) Draw a polygon.The User may select data into a polygon drawn after clicking in different points of the map. To close the polygon, the User has to double click on the last point, such that this point will be connected with the first one.
3) Draw a rectangle. To select data into a rectangular the User has to click at a point on the map and move the cursor at any direction. A second left mouse button click will restrict the selected area in its current state
4) Draw a circle (option demonstrated in figure 2). To select data into a circular the User has to click at a point on the map and move the cursor at any direction. A second left mouse button click will restrict the selected area in its current state. Note that the first click on the map corresponds to the circle's center.
5) Select all data. All available data included in the uploaded dataset is used for TDSH analysis
