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 of Induced Seismicity (ESI) and software services 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 Anthropogenic Hazard Community. 

This quick start Guide provides basic information about how to access, register and make use of the database and the services available in AH-TCS web-platform. An example of application is presented in the tutorial appended, introducing step by step the integration of data and services available in the portal. For more detailed description of the portal navigation, configuration options, scientific implementations and visualization services the user is referred to the AH-TCS User Guide. User Guide which comprises several chapters associated with specific functions, provides detailed description, supported with snapshots and figures demonstrating step-by-step examples of certain applications. This quick guide includes the most important information on the following issues:

  • Logging in

  • AH-TCS Home Page

  • Tabs and Icons

  • AH Episodes

  • Services

  • Document Repository

  • Tutorial

LOGGING IN

The AH-TCS web platform is available at https://tcs.ah-epos.eu/ (Figure 1). The language that TCS operates is English. In the home page there is brief information about TCS and relative links connected with IS-EPOS and EPOS WG10. If a user has already an account he/she can easily sign in but simply providing the e-mail address and password. To create an account, the user shall click on either the ‘SIGN UP’ or the 'SIGN UP TO GET ACCESS' tab available (shown in the red frames, Figure 1). Two classes of users will be available in the TCS: Active users and passive users. Currently, only passive user registration is enabled: The fields that the user is requested to fill are shown in Figure 2. After submitting the registration form the system generates a password which is sent by e-mail to the user and can be thereinafter used for signing in the web-platform.

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 and the Services (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 services 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 the list by impacting factor (Field 4, Figure 3). In such way the user obtains access to the selected Episode Data base. 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). The 'Actions' tab provide a list of actions. In case of the AH Episodes data, the only available action is 'Add to workspace'. 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 service', 'make a directory', etc. In the case of seismic catalogs there is also a tab 'action list' which provide visualizations of catalog elements such as tables with catalog contents, seismic activity step plot, 3D events distribution etc. There are also some actions which are defined by the following symbols

AH EPISODES

Each AH Episodes contains some informative fields describing the Episode State, Industrial process and Region, together with a short Description of the Episode and related images (Figure 4). Episode Data is found just below the Description and they are categorized into 3 groups of different data types (Field 1, Figure 4): Seismic data, Technological data and Geological data. There are additional fields shown in Figure 4:

Field 2, "All data related to this episode", grants access to the "Advanced data search"

Field 3, "Available visualizations" provides to the User the ability to perform various visualizations, regarding the selected Episode.

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

SERVICES

The available services in AH-TCS are grouped into High-Level and Low-Level Services (Figure 1), each one containing several applications (the user may extend the services by clicking on each category). High level services contain advanced methodologies for AH data analysis, whereas Low-Level services comprise tools for data transformation and handling. Information on the service is shown on the screen (short description and affiliation) and the user may upload the service in the workspace to perform applications by clicking on the 'Add to Workspace' tab.

Document Repository

Figure 6 demonstrates how the Document Repository web page looks like within the IS-EPOS platform. The "About" page is shown in Figure 6, containing contact information and useful links, that can be accessed by clicking on the text in blue fonts, found into the green boxes in Figure 6. The choices provided to the User, (tabs in red boxes, indicated by the numbers in Figure 6) are the following:

1) Leads to the AH-TCS web platform.

2 and 3)  Leads to AH-TCS Document Repository Home page. The Search Repository tool is provided here, which supports both quick and advanced search (full range of fields)

4) Leads to "Browse" page. Item can be browsed by Year, Subject, Episode, Author or Software references

Tutorial

Example of estimating seismic hazard parameters from a catalog.

Step 1: Select a specific Episode from the list by clicking on one of the panels (e.g. the one indicated by the red box)

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 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). The data has now moved to the workspace and can be processed by the means of High and Low Level Services and Visualization tools.

Step 4. Once the selected data are uploaded at the workspace (it 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 services as shown in the figure. "Source size distribution functions/ Stationary Hazard" is selected in this case.

Step 5. The service 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 a different dataset under the precondition that it is already uploaded on the workspace. Once all the parameters have been selected, the User may click on the "Run" button (green button in 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 selected by the user and estimated by the system (blue panel) and two charts, one plotting the PDF (Probability Density Function) and one plotting the CDF (Cumulative Distribution Function) of the magnitude distribution as a function 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 Service contains files in matlab format (.mat filies 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 services e.g. for estimating the Mean Return Period (red frame of the figure).
