AH-TCS is a prototype of Anthropogenic Hazard (AH) Thematic Core Service (TCS), in European Plate Observing System (EPOS) integration program. AH-TCS integrates data describing comprehensively anthropogenic hazard cases, called Episodes and software services applications grouped in certain categories. Moreover, it provides interactive visualization, browsing and optimization tools. In such way, the AH-TCS sustains a permanent and reliable platform of advanced Research Infrastructures for the AH Community. 

This quick start guide provides the basic information on how to access, register and make use of the database and the services applications available in AH-TCS web-platform, which can be accessed at https://tcs.ah-epos.eu/login.html (Figure 1).

An example of application is presented in the tutorial appended, introducing step by step the integration of data and services applications available in the portal. For more detailed description of the portal navigation, configuration options, scientific implementations and visualization services applications the user is referred to the AH-TCS User Guide. User Guide which comprises several chapters associated with specific functions, provides more detailed description, supported with snapshots and figures demonstrating step-by-step examples of certain applications.

AH-TCS HOME PAGE

The home page of AH-TCS platform is shown in Figure 3. The user may switch between the TCS portal and the Documents repository (Field 1, Figure 3). Portal grants access to three major facility categories: The AH Episodes (database), the

...

Applications (Field 2, Figure 3) and the user's workspace (Field 3 Figure 3). In the workspace the user may upload and use the available data and

...

Applications at any combination. In the example of Figure 3 the AH-Episodes is selected and the user may select an Episode from the list or filter this list by impacting factor (Field 4, Figure 3). In such way the user obtains access to the selected Episode database. Alternatively, advanced data search can be performed (Field 5, Figure 3), which provides additional filtering and searching options.

TABS AND ICONS

Most of the command tabs are self-explanatory (such as 'search', 'plot', 'show', 'Add to workspace', etc).

...

-          In case of the elements in workspace (data, results) the 'Actions' tab provides a variety of actions depending upon the format and potential usage of an element. Such actions are also self-explanatory as: 'copy', 'delete', 'use in serviceApplication', 'make a directory', etc.

Field 4, "See more information in Document Repository", leads the User to the document repository engine.

APPLICATIONS

The available services applications in AH-TCS are grouped into High-Level and Low-Level Services applications (Figure 1), each one containing several applications (the user may extend the services applications by clicking on each category).

-          High-Level Services Data Processing Applications sustain advanced methodologies for AH data analysis:

• Stationary Seismic Hazard
• Time-Dependent Seismic Hazard (in mining front surroundings)
• Time-Dependent Seismic Hazard (in mining a selected area)
• Completeness Magnitude Estimation
• Source Localization
• Moment Tensor Inversion
• Spectral Analysis
• Stress Inversion

-          Low-Level services Data Handling Applications comprise tools for data transformation and handling:  

...

Information on each selected Service Application is shown on the screen (short description and affiliation) and the user may upload the Service Application in the workspace to perform applications by clicking on the 'Add to Workspace' tab.

...

Step 2: Select a data type from the list (e.g. ‘Catalog’ in this example). There are several data types available with respect to the episode and the induced seismicity technology:

Step 3: Once the user selects one data type, access is granted to data attributes, numerical values and visualization

...

applications. For further data processing the user has to click on the "Actions" tab and then on the "ADD TO WORKSPACE" window which appears right below (red frame at the top of Figure). The data has now moved to the workspace and can be processed by the means of High and Low Level

...

applications and Visualization tools:

Step 4: Once the selected data are uploaded in the workspace (a file has appeared in the workspace tree), the user may click on the "Actions" tab in order to use these data in one of the available

...

applications as shown in the figure. "Source size distribution functions/ Stationary Hazard" is selected in this case:

Step 5: The

...

application has now been selected and the user is requested to fulfill some fields with parameter values needed for the SSH analysis (red frames in the Figure). These parameters can be selected either from a list of values (e.g. "Select Magnitude column") or just typed by the user (e.g. "Start, End and Step of Magnitude". Note that "Mmin" parameter can either be typed or chosen from the histograms after clicking on "Histogram" or "Cumulative Histogram" tabs. "Change Input" can be selected for using adifferent dataset under the precondition that it is already uploaded in the workspace. Once all the parameters have been selected, the user may click on the "Run" button (green button at the bottom of the figure), for the calculation process to be initiated:

Step 6: The process soon terminates and the status changes to "Finished". The results of the process include a report with parameters values previously selected by the user and then estimated by the system (blue panel in the figure) and two charts plotting the PDF and CDF of the magnitude distribution, respectively, as functions of magnitude. The figures may be printed or downloaded by clicking on the icons indicated in the red frame of the figure. Options for figure handling are available below the charts. 

Step 7: The output of the

...

Application contains files in matlab format (.mat files shown in the blue frame of the figure). These files can be further used in a variety of actions including downloading, copying and use in other

...

applications e.g. for estimating the Mean Return Period (red frame of the figure).
