Talk:2219: Earthquake Early Warnings

Earthquake early warning works mostly because the sensors are closer to the epicenter than the victims. The warning is transmitted at the speed of light (radio in this case) which is much faster than the earthquake waves. So the warning arrives first at a distant victim. The difference in speed of the various earthquake waves has little to do with it. The interpretation of cueballs remarks is over reaching.162.158.62.135 20:53, 23 October 2019 (UTC)

Wikipedia disagree with you saying that you might get a warning from a few seconds to more than a minute just based on P-waves which move faster than S-waves. Have added this link to the description. --Kynde (talk) 21:26, 23 October 2019 (UTC)
