Seismic Waves
The USGS operates a really neat email/SMS earthquake notification service (earthquake.usgs.gov/ens/) that allows fine-grained control of notifications.
Title text: The USGS operates a really neat email/SMS earthquake notification service (earthquake.usgs.gov/ens/) that allows fine-grained control of notifications.

Explanation

One stereotype surrounding twitter users is that they are more concerned with tweeting their current status than they are with addressing it. Earthquakes are natural disasters caused by the movement of the Earth's tectonic plates, known for the destruction that they leave in their wake. The comic outlines the potential that technology can have in warning people about earthquakes, which is unfortunately negated by the tendency of the typical users of the technology to care more about sharing the warning message than they are to preserve their own lives.

Transcript

When an earthquake hits, people flood the internet with posts about it--some within 20 or 30 seconds.
[A room with a desk, chair, and computer are shaking. The person in it is on his phone, using Twitter.]
RobM163 Huge earthquake here!
Damaging seismic waves travel at 3-5km/s. Fiber signals move at ~200,000kh/s.
(minus network lag)
This means when the seismic waves are about 100km out, they begin to be overtaken by the waves of posts ABOUT them.
[There is a geographical border on a map; the front edge of the wave of the quake is shown, with the front edge of the wave of tweets surpassing it.]
People outside this radius may get woord of the quake via Twitter, IRC, or SMS BEFORE the shaking hits.
[Megan and Cueball are standing, holding cell phones. Megan is looking at hers.]
Megan: Whoa! Earthquake!
Sadly, a Twitterer's first instinct is not to find shelter.
Megan and Cueball (on phones): RT @RobM163 Huge earthquake here!

Discussion

Twitter user RobM163 exists and was created along with this comic (presumably by Randall). He tweeted a few times about various disasters on April 5th, 2010, and later on the 22nd about Iceland's not being a great tourist destination (due to Eyjafjallajökull).

RobM163's first post was the day before the xkcd comic. Z (talk) 17:14, 7 June 2014 (UTC)

But, if the earthquake damages the area's communications infrastructures... 108.162.250.210 (talk) (please sign your comments with ~~~~)

All the way here in 2016 it seems worth mentioning: the ubiquity of smartphones means peer-to-peer chat is positioned to survive this type of service disruption. It seems only a matter of time that getting online from a disaster zone will mostly depend on there being a smartphone chain leading to the closest public AP outside the blackout zone.

What about twitterer? Twitter user and tweeter are better alternatives for OCs. Might be a reference to (this:)). Well, Twitter user is too long when tweeting during an earthquake (and the tweet may exceed the 140), and tweeter might be in reference to this: Tweeter 172.68.144.109 (talk) (please sign your comments with ~~~~)

The USGS ENS one from the title-text works for me. Unless you mean another. 172.69.194.96 23:16, 25 June 2024 (UTC)

Has anyone noticed that this should be x now, not twitter? -- Jnutlikesxkcd (talk) 01:21, 8 July 2024 (please sign your comments with ~~~~)

Really? Aww man... Just checked, and you're right. Look, I can't keep track of every little fiddly rebranding that happens when I'm busy trying to get my Geocities page back up on FIDONet with all the latest info on what Napster hits are available on Vine... 141.101.99.147 02:58, 8 July 2024 (UTC)
