: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 {{w|P-wave#As_an_earthquake_warning|which move faster}} than S-waves. Have added this link to the description. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:26, 23 October 2019 (UTC)

Anyone else think this drawing is weirdly grey compared to other recent ones? - Anonymous (how edgy!) 22:21 23 October 2019 (UTC)

That's why I don't use the bun spoiler app. --[[Special:Contributions/172.68.245.193|172.68.245.193]] 23:16, 23 October 2019 (UTC)

(Dark humo(u)r...) Would a Mass Shooting alert app involve a "trigger warning"? (/Dark whatever). [[Special:Contributions/162.158.158.127|162.158.158.127]] 18:21, 25 October 2019 (UTC)

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 talks about "p-waves before the obvious main wave", which is likely a reference to p-waves vs. surface waves.
