In an earthquake noticing system according to the present invention, an earthquake noticing server receives focal data, calculates an expected time of arrival from a distance calculated from an occurrence location of an earthquake, a self-location and a focal depth, calculates an estimated seismic intensity from the occurrence location of the earthquake, the self-location and the seismic magnitude, calculates a corrected value of the expected time of arrival from the occurrence location of the earthquake, the self location and the location of a sub-terminal, and transmits the corrected value and estimated seismic intensity to the sub-terminal.
