Earthquake!!

Inspiration

I develop websites about earthquakes for UCSB Earth Research Institute. My job inspired me to make a Pebble Watch app to show the most recent earthquakes within California.

How it works

Pebble.js SDK + Pebble iOS app + JavaScript + USGS API -> Earthquake!!

Earthquake Source:

USGS earthquake GeoJSON API, which updates every 5 minutes

Process

Javascript running on iPhone requests earthquake data though USGS's API, parses the returned results, and display on Pebble Watch.

Features

• Shows Earthquake basic info: time, place, coordinates, depth
• Updates every 5 minutes when the app is active(not terminated)
• When new earthquakes fetched, pebble watch will give you a quake
  
• Shows distance from user to the earthquake source ## Challenges I ran into Pebble.js is under active development, so I met two bugs that were from the SDK itself and costed me a few hours to debug. ## Accomplishments that I'm proud of
• Finished the app implementation

What I learned

• How Pebble Watch works
• Markdown
• Calculation of the distance between two coordinates

What's next for Earthquake!! -- Pebble Watch Earthquake Feed App

A companion iOS/Android app, along with the Apple push notification service can make this app a "real-time" (5-minute accuracy) earthquake notifier even when this app is not running in foreground.

Built With

• geojson
• javascript
• pebble
• pebble-ios-app
• pebble.js-sdk
