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 period 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.
Show catalog (field 2, Figure 6): Detailed information on the attributes of every event in the seismic catalog is demonstrated (Figure p1). These data appear as pop-up windows and are shown in pages, each one containing 20 rows. The User can proceed to the following or previous pages by clicking the left-right arrows shown in the bottom left part of Figure p1.
Figure p1.
- Seismic Activity Step plot (field 23, Figure 6): This option shows the seismic activity plotted against time (Figure p1p2). Zooming in/out and linear/logarithmic scale of the y-axis are available.
Figure p1p2.
- 3D events distribution (field 34, Figure 6): 3D spatial distribution of the events foci (longitude,latitude,depth), as circles with size proportional to the event magnitude (Figure p2p3). Rotation of the plot is possible after clicking and dragging the cursor through the plot area. The focal coordinates of each event are depicted when the cursor is pointing on a circle.
Figure p2p3.
- Benioff plot (field 45, 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 p3p4). Zooming in/out and linear/logarithmic scale of the y-axis are available.

- 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 those are available). Zooming in/out option is available for this figure.
