Services

In the present platform version the available services ("Services" tag in the IS-EPOS main page) are grouped into the categories shown in Figure 1, each one containing several applications (click on each category to extend the services):

Figure 1.

• Low level-services (Figure 2) comprise the following applications (See "Low Level Services" chapter for a detailed description):

Figure 2.

• High level services contain advanced methodologies for Anthropogenic Seismicity data analysis grouped as indicated in Figure 3. Note that each one of the High Level Services are described in detail in special chapters.

Figure 3.

Each one of these categories contain a number of applications that the user can utilize for episode data analysis. These applications are available after clicking on one of the categories and then on "add to workspace" panel (Figure 4) and comprise in detail:

• Collective properties of seismicity:
  • Source Size Distribution
  • 1. Completeness Magnitude Estimation
    2. Source Size Distribution Functions (Also found in the next category)
• Probabilistic Seismic Hazard Analysis - stationary
  • Hazard Parameters Estimation
    1. Exceedance Probability
    2. Maximum Credible Magnitude
    3. Mean Return Period
  • Source Effect
    1. Source Size Distribution Functions (Also found in the previous category)
• Probabilistic Seismic Hazard Analysis - time dependent
  • 1. Time Dependent Seismic Hazard Parameters
  • Stationary inducing factor
    1. Time Dependent Seismic Hazard Parameters for Stationary Geometry
  • Time Varying inducing factor
    
    1. Time Dependent Seismic Hazard Parameters for Time Varying Geometry
• Source Parameter Estimation
  • Earthquake Spectra
    1. Spectral Analysis
  • Source Location
    
    1. Localization (TRMLOC)
  • Moment Tensor Inversion
    
    1. Moment Tensor Inversion (FOCI)
• Stress Field Modeling
  • 1. Stress Inversion from Focal Mechanisms

Alternatively the user may browse an Episode, upload the data he/she wishes to use for analysis to the personal workspace, and then use these data for visualization, high level application or low level (Simple Component) application (see figures below).

Step 1: Browse Anthropogenic Hazard Episodes by clicking on "AH Episodes" tag in the top left corner of the main menu (tag into the red frame in Figure 5):

Figure 5.

Step 2: Select a specific Episode from the list by clicking on one of the panels (e.g. the one indicated by the red box in Figure 6):

Figure 6.

Step 3: Select a data type from the list (e.g. catalog in the example shown in Figure 7). There are several data types available with respect to the episode and the induced seismicity technology:

Figure 7.

Step 4: Once the User selects one data type he obtains access to data attributes, numerical values and visualization services. For further data processing the User has to click on the "Actions" tab and then on the "ADD TO WORKSPACE" window which appear right below (red frame at the top of Figure 8):

Figure 8.

Alternatively, the User may continue from step 2, through the following process:

Step 3b: After selecting an episode the user may receive access to all available data from any episode by clicking onthe "All data related to this episode" tab (red box, in the bottom left corner of Figure 9).

Figure 9.

Step 4b: A Data search screen is now displayed (See also "Advanced Data Search" in "AH Episodes" chapter). The User may either select one or more (even all) episodes, or apply a filter from the list provided such as time range, country, data type etc (Figure 10).

Figure 10.

Step 5b: All data after the filtering criteria application is now demonstrated and the User may select one or more data types for further processing. If the User chooses the "View File" tab, the same screen as in Step 4, appears. If the User clicks at the "Add to Workspace" tab, the data is directly transferred to his/hers personal workspace (Figure 11). 

Figure 11.

Once the selected data is uploaded at the personal workspace, the User may click on the "Actions" tab in order to use these data in one of the available services, grouped into 3 categories: "USE IN APPLICATION", "USE IN VISUALIZATION", "USE IN SIMPLE COMPONENT". This is the Data Oriented Approach shown in Figure 12.

Figure 12.

Alternatively, a Service Oriented Approach can be followed as displayed in Figure 13. The User selects the service first and then clicks on the "Change input" tab for choosing (Shown in the red frame of Figure 13) the appropriate input data file(s).
