Once the parameters are set, the User may click on the "Run" button (blue button at the bottom of Figure 4) and the system produces the results of visualization, as shown in Figure 5.The events constrained by the spatial-temporal-magnitude criteria previously determined, as shown in a map, as circles with size proportional to their magnitude (red circles, Figure 5). The front position is also demonstrated as a black line in Figure 5 and it can be hidden/shown by ticking the box at the left of "Show Mining Front Advance" tag, in the top left corner of the map in Figure 5 (for additional map options, see "Maps Guide" section in the end of this Chapter).

Figure 5.

Four vectors with output results, corresponding to data extracted are also produced (shown at the left of Figure 5) and they are the front position, the latitudes, longitudes and magnitudes of the events.. These vectors are available for further processing and can be used as input for other applications. By clicking on any of them in the list, the values of the vector appear in the screen (for example magnitude "m" as shown in Figure 6). These values can be either plotted as 1-D plot (click on "Show" button, indicated by the green box in Figure 6 - see "Plot Properties" later on this Chapter for details), or used in a variety of applications as demonstrated in Figure 6 (red frames).

•  Integrated episode data Visualization: This is an alternative way to access integrated Episode data visualization, already described in "AH Episode Chapter".

 In Addition to those Visualization Services, a tutorial is here presented for some other, useful visualization tools applied in the platform (Waveform Viewer, General Plot Properties ans Maps Guide):

•  Waveform Viewer Guide: Waveform viewer is a seismic waveform processing tool. The User may observe, interact and elaborate waveforms corresponding to signals recorded by seismic stations and perform various actions such as phase determination and point picking. These pickings are saved by the system and can be further used in waveform-based services such as Spectral Analysis, Source Localization and Moment Tensor Inversion. The options provided by the waveform viewer are described in Figure 57:
  When clicking on one waveform, additional options appear.The user selects the component(s) that he/she wishes to be displayed in the screen. East-West, North-South, Vertical.

Figure 7.

1. The user selects the component(s) that he/she wishes to be displayed in the screen. East-West, North-South, Vertical.
2. Horizontal zooming in-out.
3. Vertical zooming in-out.
4. Undo all zooming.
5. Select between phase (start and end point) picking and single point picking.
6. Only P-wave is enabled in this Application. (In other Applications, selection between P-wave and S-wave picking are possible, see "Waveform viewer guide" in "Visualization" chapter).
7. Undo picking.
8. Horizontal zooming tool. The User may alternatively zoom in-out the waveform by clicking on this small vertical bar and move the mouse left-right. The User may also click and drag the selected (shaded) part of the waveform left and right.
9. Collapse the details of the waveform.
10. Move the selected (zoomed) part of the waveform left-right.

...

The User has to pick a starting and an ending point from the Vertical component of a station (**Z channel - see Figure 68). Then, he/she has to repeat this picking for the other stations.

Figure 68.

The number of the seismograms and P-wave phases picked, are updated, each time the User selects makes a new picking.

•  Plot Properties: All Figures open in pop-up windows and they can be closed by clicking at the 'x' in the upper right corner, or just pressing Escape button.

• 1-D and 2-D plots - including 1-D and 2-D plots with secondary Y-axis (Figure 79): These plots give the capability of choosing between linear and logarithmic scales for X and Y axes (ticking on small boxes, field 1, Figure 79) and selection of diverse graphic views among scatter plot, spline, column and line (field 2, Figure 79). By holding the cursor still onto an option or in a figure element [e.g. bar in histograms or points in scatter plots], information on this option or element appears on the screen (field 3, Figure 79). Plotted parameters may be hidden and re-appear by clicking at the legend (field 4, Figure 79). The user may save a selected figure (field 5, Figure 79) in one or more of the following formats by clicking on the square panel: .png, .jpeg images, .pdf document or .svg vector image. Alternatively, for some figures the user can download the corresponding data and save them in .csv format in order to use it for further analysis. The figures can also be printed directly (field 6, Figure 79). Many figures have enabled zooming services for focusing in a specified range among the values. This is achieved by clicking at a point of the figure and dragging the mouse cursor either leftwards or rightwards. Instructions are shown at the bottom of the figure as well (field 7, Figure 79). Zooming can be reset by clicking on the "Resert Zoom" tab shown in field 8 of Figure 79.

Figure 79.

• In addition to the previous mentioned options. Histograms, Cumulative Histograms and Reverse Cumulative Histograms also provide the possibility for the user to adjust the step (width) of the x-variable (indicated in the red box, Figure 810).

Figure 810.

• 3-D images are equipped with a rotation function (instead of zooming), activated by holding the left click and moving the mouse Figure 911. 

Figure 911.

•  Maps Guide: All google basemaps have in effect the following well known tools (an example is demonstrated in Figure 1012): Moving at any direction in the map by clicking and dragging the hand pointer throughout the map. Alternatively, the User may shift the map at any direction by using the arrows shown in field 1 of Figure 1012.The street-view imaging tool can also be applied (field 2, Figure 1012). Zooming in/out can be performed mouse rolling, or, alternatively, by using the zooming tool (plus-minus boxes and small bar) shown in field 3 of Figure 1012. The map scale is updated after any zooming action and is shown at the right bottom corner of the map (indicated by the blue frame in Figure 1012). The User is also given the chance to select between Map view and Satellite image (field 4, Figure 1012). Terrain and Labels, respectively, can be shown or hidden. Finally full screen mode can be activated after clicking in the "Full Screen" tab (field 5, Figure 1012).
