Most smartphones have accelerometers.
Earthquake waves move surprisingly slowly.
Sign up on the website, download the app.
When an earthquake is detected you get a loud warning tone and a
splash screen telling you to put your phone flat on the floor RIGHT
NOW.
The phone records any tremors
and its GPS location, then uploads to
the server. The data quality is poor, but there are many, many
identified sampling points.
As a bonus, rescuers may have a better idea where to dig- for your
phone, at least.

//put your phone flat on the floor// |

One problem is that the phone is likely to slide, if the
floor is moving sideways at more than a very low
frequency. |
|

Lie down on the phone. This will protect it somewhat from being crushed. |

A bit late to the party, [8th of 7]. This idea was all the rage after the 2011 Christchurch earthquake swarm. I can't find a decent link, but there's MyShake among others. |

... population 300,000 sheep, two dozen Maoris, five small brown flightless birds, and a markedly indifferent rugby team. |
|
| |
Not a big sample size, then. |
|
| |
What on Earth are Maoris doing in Cornwall? And why
do they need so many sheep? |
|
| |
(a) Asylum seekers, driven from their native land by crashing boredom. Even Cornwall is an improvement, which tells you how bad NZ is. |

(b) Ask the Intercalary. If you're unlucky, he'll explain by showing you some of his home videos. |

Uhh...can it screen out the motion from the user running away? |
|
| |
It doesn't have to. The user's duty is, as stated above, to lie on top of the phone and protect it, if necessary sacrificing their life for Science. |
