Page History

Some visualizations connected with the Services are described in this section. There are some special visualizations for mining-induced seismicity.They can be accessed from the 'Mining Front Advance' file (Figure 1), uploaded to the workspace from the AH-Episode database.The User may click on 'Actions' tab, then on 'USE IN VISUALIZATION' tab, and then select among the 3 visualizations shown in the right red panel of Figure 1 (for "Integrated episode data visualization", see AH-EPISODES Chapter).

Figure 1.

•  Seismic Activity with Front Advance: This is a service dedicated to mining induced Episodes and is directly connected with the Time Dependent Seismic Hazard Service. Figure 1b shows the input that is necessary to perform this visualization:
  1. Input files are 'mining front advance' and the corresponding seismic catalog, imported from the AH-Episode database.
  2. Chose line date: The User selects the date that the front is in a certain position, either by selecting a date from the available list, or by clicking on a certain line in the 'Front Advance Plot' (right part of Figure 1b.)
  3. 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).
  4. Mmin: The User now is requested to chose the minimum magnitude (completeness level of the catalog). This can be done in two ways. The first is to type a single magnitude value in the empty box, possibly after he/she has performed an individual analysis (see MCE service). The second is to graphically select the minimum magnitude from the Normal or the Cumulative histograms, which are available after clicking on the respective tabs. In both cases there is option to alter the step of the histogram's bars and to select between linear and logarithmic scale of the Y-axis for the plotting. The magnitude range is also shown in the screen.

The User may have access to special visualization services as shown in Figure 1. This screen appears after clicking on "Services" tab from the home page of IS-EPOS web platform and the selecting "Low-level services" (options in the red boxes, Figure 1). A list of visualization services is shown (appended after the other low-level services), with a brief description appended and option to add the service in the workspace (clicking "Add to workspace" tabs, indicated by the blue boxes in Figure 1). Clicking anywhere into the area constrained by the green frame in Figure 1, would show an overview of the service with additional information, such as input files, references, affiliation, output results etc.

Figure 1.

•  Front Advance Histograms Visualizations: This is a service dedicated to mining induced Episodes and is directly connected with the Time Dependent Seismic Hazard Service. It provides histograms of seismic events and seismic energy release for constant steps of mining front advance. The data needed for this services comes from the AH Episodes (see this chapter) and in particular Bobrek Mine seismic catalog and Bobrek mine front advance, as depicted in Figure 2, next to "Using Seismic catalog" and "Using mining front advance", respectively. Any other, previously filtered catalog can be introduced as well. In addition, the front window size is requested to be set by the user (in meters).
