Page History

There are multiple ways to access the AH Episode data available in the IS-EPOS web platoformplatform.The User may click on the "AH Episodes" tab from the portal main menu on in the upper top left corner of the screen (Field 1, Figure 1). In such way the available episodes are displayed on the screen along with options for selecting /and filtering data. "Advanced data search" (field 2, Figure 1) will be described later on in this section. The User is provided the possibility for selecting among AH Episodes according to technologythe technological/production process they are connected with. This can be done by ticking the small boxes shown in field 3 of Figure 1. Ticking "All" box, will exclude no Episode from the list displayed (field 4, figure Figure 4). The User can now click on one of the Episodes (e.g. Bobrek Mine, or Czorsztyn) from this list to get access to the corresponding data.    

...

For each one of the AH Episodes from the list, some short information concerning the technology location and the region technology associated with the Episode is provided. In addition, a world map is shown in at the lower part bottom of the screen with the exact location of the selected episodes indicated depicted on the map (Figure 2). Zooming, map/satellite view, drawing of national borders and full screen mode are options provided for the map handling.  

Figure 2.

Figures 3 and 4 show demonstrate an example of a page with data from Bobrek Mine Episode. The structure and interface is identical in all cases of AH Episodes. Some informative fields are displayed in the upper part top of the screen such as the Episode State, Industrial process and Region, together with a short Description of the Episode (Figure 3). Some figures connected images related with the selected Episode are also displayed, providing additional information. Episode Data is found just below the Description and they are categorized into 3 groups with of different data types (Field 1, Figure 4): Seismic data, Technological data and Geological data

...

Seismic Data includes mainly seismity seismicity catalogs, seismic network information and waveforms corresponding to seismic events as they were recorded by the stations. Geological data include mainly velocity models from the site of the Episode and maps with local faulting systems. On the other hand, Technological data contains a group of data files which is directly connected with the technological-production processes that induce the anthropogenic seismicity (see the example from Bobrek Mine Episode, Figure 4).    

Figure 4.

There are additional fields shown in Figure 4: Field 2, "All data related to this episode", gives grants access to the "Advanced data search", which will be described later on in this section. "Available visualizations" (field 3, Figure 4) provides to the User the ability to perform integrated Episode data visualization and various other visualizations, regarding the selected Episode. Finally, clicking on field 4 of Figure 4, "See more information in Document Repository", leads the User to the document repository engine, to seek for references and further details concerning the Episode, data, methods etc.

All of the aforementioned data sets can be selected by clicking and then added to workspace and be used in (selecting "Add to workspace" from the "Actions" tab, e.g. field 1, Figure 6) to be used for the available services. For some of these data sets, visualization is also shownpossible, as map view (e.g. Seismic Network, mining area, reservoir shoreline) or graph charts (e.g. Velocity velocity model, mining front advance, injection rate). The map view - like data can be combined and demonstrated in a single map by selecting the "integrated Episode data visualization" from the "Available Visualizations" tab. Seismic events (red circles), network of seismic stations (green triangles) and various episode-related data can be shown/hidden by setting/deleting a tick in the small boxes shown in the upper part top of figure Figure 5. 

Figure 5.

Additional options are available for some specific kinds of data (Catalog and Water Level/ Wellhead pressure with seismic activity, e-D visualization and Integrated GIS data), therefore, these will be now described in detail.

•  Catalog Options (All episodes)

...

Seismic catalog contains various important information as demonstrated in Figure 6 and Figure 7. The User may upload the catalog data in the workspace by selecting "Actions" (field 1, Figure 6) and then "Add to workspace". Below this field, a short summary of the catalog is provided, containing the number of events, time rangeperiod that the Episode covers, depth range of seismicity and magnitude range of the events. Below the summary, there are some action tabs (fields 2-6, Figure 6). The attributes of the catalog are displayed below these tabs, and they comprise the Name of the attribute, a brief description, the minimum and maximum values and the number of valid values (i.e. values that exist, not NaNs). The action tabs are the following (also see "plot properties" section in "Visualizations" chapter):       

Figure 6.

• Seismic Activity Step plot (field 2, Figure 6): Seismic This option shows the seismic activity plotted against time (Figure p1). Zooming in/out and linear/logarithmic scale of the y-axis are available.

Figure p1.

...

• Benioff plot (field 4, Figure 6): A Benioff  plot (square root of energy against time) can be created for those catalogs which include information on seismic energy released by the seismic events (Figure p3). Zooming in/out and linear/logarithmic scale of the y-axis are available.

Figure p3.

• Show catalog (field 5, Figure 6): Detailed information on the attributes of every event in the seismic catalog is demonstrated (Figure p4). These data appear as pop-up windows and are shown in pages, each one containing 20 rows. The User can proceed to the following of or previous pages by clicking the left-right arrows shown in the lower bottom left part of Figure p4.

Figure p4.

• Events in local coordinates (field 6, Figure 6):This option generates 2-D plot of the epicentral coordinates of the seismic events (Figure p5) in local (cartesian) coordinate system (when these those are available).  Zooming in/out option is available for this figure.

Figure p5.

Additional plotting options are available be clicking on the gear icon shown in field 7 of Figure 6 (right hand side). These options include histograms (interval, cumulative and reversed cumulative histograms) and 1-D plots.  Zooming in/out and linear/logarithmic y-axis are available. Moreover, in histograms the bar step can be modified and in 1-D plots the chart type can be switched among column, scatter, spline and line.
