Using estimates for ionospheric delays of radio navigation signals from a network of IGS stations, we analysed ionospheric variations over the epicenters of two great earthquakes: in Haiti in January 2010 (М = 7.2) and in Japan in March 2011 (М = = 9.0). Some characteristic features, which were common for both earthquakes, were revealed for changes in the local ionosphere region state over the epicenters of the earthquakes
