[7] The developed software complex can be easily used for modeling the generation and propagation of tsunami waves from a dynamic source in various water areas. Below we describe the possibilities of this complex.

[11] 3. Module specifying calculation parameters and display parameters of results;
[12] 4. Module specifying dynamic sources and their characteristics;
[13] 5. Module displaying and saving results;
[14] 6. Computation module.
[15] Below we illustrate the operation of these modules in more detail.
[16] The module of transformation of initial data reads the initial data file, corrects the data, and converts them into the binary format. In addition, the module allows the user to choose a part of the given water area that will be used for calculations.
[17] Module 2 loads the data file into memory; the data are used for calculations and for the initialization of arrays required for the calculations and saving of their results.

[22] (ii) The Show Terr tool enables the display of the bottom topography and the dynamics of block motion. The result can be saved in the bmp format (Figure 6).
[23] In addition, the following functions of automatic saving of pictures in the process of computations are implemented.
[24] (iii) The Show max H and Show min H tools display the current maximum and minimum values of wave heights in the water area. These tools are active only if the process of computations is in progress or interrupted. The result can be saved in the bmp format.
[25] (iv) The Show Eta tool displays current values of wave heights in the water area. The tool is active only if the process of computations is in progress or interrupted. The result can be saved in the bmp format. If the auto option is inactive, results are not saved.

[27] (vi) Show data window can be active only during the computation process. If active, this tool displays a floating popup window showing the following values: h, ocean depth at a given point; u and v, velocities of wave particles at the given point along the X and Y axes, respectively; vis, current wave height at the given point; max vis and min vis, maximum and minimum ocean surface heights at the given point over the entire time of computations; C, wave front velocity (Figure 8).
[28] Thus, we have complete information on the water area throughout the computation process.

[31] Computation module provides for the possibility of a new run, its saving, its interruption and renewal, and the test run, i.e., the computation in the same water area with a fixed depth value.
