Research of the Dynamics and Propagation of Long Waves in the Coastal Area Using Satellite Data

The paper presents the results of research work on the development of a “Database of subject-specific features and spectral characteristics” (according to the “Database of PSPSH). Most tsunami events (about 80%) are caused by strong underwater earthquakes. In some cases, tsunami formation owes to landslides (6%), volcanic eruptions (5%), and meteorological causes (3%). As a result of the scientific expedition on the Kuril Islands, comprehensive ground-based studies of test sites for testing the spectral hardware and software complex were carried out. The database was tested in some areas of the Sakhalin region. Within the framework of the carbon landfills pilot project, the database development will be used in the Kuril Islands in 2023 to monitor natural and anthropogenic systems in the context of global environmental changes, as well as to search for areas of seismicity and tsunami impact.
