AB: Regardless worldwide studies of anomalous variations of the electron concentration appearing in the ionosphere few days before the seismic shock and named ionospheric precursors of earthquakes, the facts on such events over the United States are very poor. The paper intends to fill this gap presenting data on several well known strong earthquakes in the United States: Good Friday earthquake of March 1964, Mammoth Lake seismic swarm of May 1980, Hector Mine earthquake of 1999, and recent San Simeon earthquake of December 2003. The data of topside sounders of Alouette and Intercosmos-19 satellites are used, as well as GPS total electron content measurements. The physical mechanism of the seismo-ionospheric coupling is discussed together with possible application techniques for the ionospheric precursors identification.
