  A promising perspective is presented that humans can provide hourly warning
for strong land earthquakes (EQs, Ms6). Two important atmospheric electrostatic
signal features are described. A table that lists 9 strong land EQs with shock
time, epicenter, magnitude, weather in the region near the epicenter, precursor
beginning time, and precursor duration demonstrates that at approximately
several hours to one day before a strong land EQ, the weather conditions are
fair near the epicenter, and an abnormal negative atmospheric electrostatic
signal is very obvious. Moreover, the mechanism is explained. A method by which
someone could determine the epicenter and the magnitude of a forthcoming strong
EQ is suggested. Finally, the possibility of realizing hourly warning for
strong land EQs in the near future is pointed out.
