In addition, the sensors send the warning electrically - at the speed of light - much faster than either P-waves or S-waves. Because of these differences in speed, the network can send warnings through the app about 5-20 seconds before major shaking occurs, enough time for people to take cover under tables, run outside, etc. The farther you are away from the epicenter, the more warning time you have. |
In the comic [[Megan]] talks about the app, suggesting how cool it is, but [[Cueball]] is upset. He seems to think that prediction of the earthquake coming is like a spoiler that ruins the experience of how an earthquake should be experienced. Apparently he prefers to simply be taken by surprise like most people are when an earthquake large enough to feel hits. | In the comic [[Megan]] talks about the app, suggesting how cool it is, but [[Cueball]] is upset.
