A system for automatically constructing maps of isoseist strong events has been created, a server has been launched to collect data from remote stations, which sends a warning about an expected earthquake via telegram-bot.</p><p><em>Application field of research.</em> The results obtained make it possible to implement a warning system about strong earthquakes, which can be used in the Ministry for Emergencies to assess the situation, protect critical facilities (dams of large reservoirs, nuclear power plants, etc.) quickly.</p> ER -
