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