Earthquake early warning for railways: perspectives, problems and solutions

The train speeds and general load of the railways will be increasing in the future. This is caused by Railway Transport Development Strategy of the Russian Federation. Hence the earthquakes hazard also is increasing. Early warning system is one of the most effective instruments to reduce damage from earthquakes. It allows taking automatically action to protect railway objects and life of people. Also it takes into account the possibility of a rapid estimation of damage. This is necessary for effectiveness of rescue and repair activities. Specifics of such system in our country require development new algorithmic and software solutions. It is required to create minimum sufficient configuration with a possibility of further modernization and integration into regional warning systems. Results of development individual components of system, including the general ideology of its construction are presented.
