Space storms as natural hazards

摘要

Eruptive activity of the Sun produces a chain of extreme geophysical events:high-speed solar wind, magnetic field disturbances in the interplanetaryspace and in the geomagnetic field and also intense fluxes of energeticparticles. Space storms can potentially destroy spacecrafts, adverselyaffect astronauts and airline crew and human health on the Earth, lead topipeline breaking, melt electricity transformers, and discontinuetransmission. In this paper we deal with two consequences of space storms:(i) rise in failures in the operation of railway devices and (ii) rise inmyocardial infarction and stroke incidences.
