−	Surface waves cause nearly all of the damage of an earthquake, not s-waves (shear waves). This should be updated. P-waves, or primary waves, arrive first and are compression waves which can also be used to determine the alignment and type of earthquake, such as a normal or reverse fault. S-waves, or secondary waves, follow the p-waves and are shear waves which do cause more damage than p-waves, but they cause far less damage than surface waves, such as Rayleigh and Love waves. Surface waves arrive last, but cause by far the most damage. Randall ~~does talk~~ about ~~the~~ p-waves ~~vs.~~ the ~~s-waves~~, ~~but~~ p-waves ~~and s-~~waves ~~are typically not felt by people during an earthquake~~.	+	Surface waves cause nearly all of the damage of an earthquake, not s-waves (shear waves).

	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.[[Special:Contributions/162.158.62.135\|162.158.62.135]] 20:53, 23 October 2019 (UTC)		Earthquake early warning works mostly because the sensors are closer to the epicenter than the victims.
