  9. EEW Earthquake Early Warning Launched by the Japan Meteorological Agency(JMA) on October 1st, 2007 Seismometer P-waves Primary waves (P-waves) JMA Secondary Waves (S-waves) S-waves P S amplitude Hypocenter (focus) time seismometer output 4km/s 7km/s This time lag provides valuable secondsfor self-protection and evacuation. e.g.) Seismometer at your city is 56km away P arrives after 8 sec S arrives after 14 sec More than 4,200 seismometers installed GSC-18, 22-23 July 2014, Sophia Antipolis

  10. Special ring tone when alert received Early Warning Message • By Mobile OperatorsMessages are transmitted to mobile devices via “Cell Broadcast Service” • By BroadcastersMessages are transmitted to TV sets via “Superimpose” CBS Warning Message No transmission to mobile deviceswhere Earthquake warnings are not in effect.
