==Explanation==
{{incomplete|Created by a SPOILED EARTHQUAKE. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

A week before this comic, on October 17th, California introduced an {{w|earthquake warning system}} in the form of an [https://www.latimes.com/california/story/2019-10-16/california-to-launch-statewide-earthquake-early-warning-system app for smartphones called MyShake].
The system works through a network of sensors across the state that can detect {{w|P-waves}} from an {{w|earthquake}}, {{w|P-wave#As_an_earthquake_warning|which move faster}} than the {{w|S-waves}}, which cause most of the damage.  Because of this difference 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 earthquake, 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 tries to recognize the P-waves before the S-waves hit; this is a challenge, as people cannot feel the P-waves as easily as the S-waves.

He also personifies the {{w|tectonic plates}} (whose shifting positions causes the quake), saying that we should all feel the shaking the way the tectonic plate intended.

Earthquake warnings, on a smartphone but not as an app, were the topic of [[723: Seismic Waves]], and shortly before that a protip for an alternative seismograph was mentioned in [[711: Seismograph]].

In the title text Cueball mentions that he was fired from the {{w|National Weather Service}} five minutes after they hired him because the first thing he did was to rename {{w|tornado warnings}} as {{w|tornado}} spoiler alerts. A {{w|Spoiler (media)|spoiler alert}} is something used, for instance, when talking about a plot twist of a new movie, so that people who haven't seen the movie can avoid learning important details that would spoil the experience of seeing the movie. Cueball seems to genuinely wish to be surprised by these potentially lethal phenomena for which just minutes of warning may make the difference between life and death.

An app for warning about tornadoes was the topic of [[937: TornadoGuard]]. Warnings in general by the NWS were the subject in [[2179: NWS Warnings]]. Tornadoes was mentioned here, as was volcanoes and Tsunamis, the later often caused by Earthquakes, but quakes were not mentioned.

==Transcript==
:[Megan is looking at her phone while standing next to Cueball]
:Megan: Ooh, California has a new earthquake early warning app.
:Cueball: Yeah, I'm so mad about it.

:[Megan puts her phone down and looks at Cueball who throws his arms up in the air.]
:Megan: What, why?
:Cueball: It ruins the experience of trying to recognize the p-waves before the obvious main waves hit.

:[Megan still looks at Cueball who has taken his arms down.]
:Megan: So you're mad about earthquake ''spoilers?''
:Cueball: I just want to experience the shaking the way the tectonic plate ''intended!''
