statsbadge-quakes

Recent earthquakes on a world map, for statsbadge.

The page cycles through the set on its own, closing in on each event and pulling back out to cross an ocean. Rings leave the epicentre in the magnitude's own colour off the theme ramp, so how big it was is something you can read at a glance from across the room. Under the map: the magnitude, where it was, how deep and how long ago.

Events come from USGS, which needs no key and no account.

Install

statsbadge ext add quakes

Notes

The map is the badge firmware's own, so nothing is downloaded and no geometry crosses the network: the host sends ten events and the badge knows where they are. Land takes its colour from the theme ramp by latitude, tropics at the hot end and ice caps at the cold one, so the map is themed along with everything else.

The last set is kept, so a badge switched on before the network is up draws the quakes it knew about rather than an empty world.

Largest magnitude, Latest magnitude and How many are offered as readings too, under Earthquakes in the field pickers, for a text or dial page that wants a number rather than a map.

The feed is asked for every five minutes and the badge polls every second, so the events are sent only when they change: an age is drawn to the minute and worked out against the minute just gone, which is what lets a set that has not moved be a set that is not sent. Ten events are about 1.1KB, so that is 1.1KB a second saved for a page that changes twelve times an hour.
