This app downloads the United States Geological Survey (USGS) data on worldwide 2.5 magnitude and above earthquake activities of the past 7 days.

Every time the table view is pulled down, a "Pull to Refresh" control adds the most recent earthquake(s) to the list of earthquakes.

The earthquakes list includes the location, date, time, latitude, longitude and earthquake depth data.

A map view can be generated for each earthquake listed in the table view by entering its latitude and longitude coordinates on a 2nd view. The map will then be scaled to the general earthquake region, pin-pointing the epicenter of the quake with of a drop pin.

To evaluate the relative severity of earthquakes a list of worst earthquakes in history is provided on a third view.

This is a nice app but what it really needs is the ability to utilize the iPhone accelerometer to detect earthquakes and automatically share that data to the cloud and/or the USGS.

Only when enough similar readings are detected from a certain region within a narrow timeframe would the data be considered legitimate and then be pushed back out to the map for all users to view.

The app could also be active only at certain times of the day/night that the user defines. As well as only be active when connected to pre-defined wifi networks. Such as Home or work.

Another option would be to only take accelerometer reading when it is plugged into power (such as when on your night stand or connected to a computer USB).

The app could also use the iPhone GPS to disable sensor reading when moving. As well as only record seismic data when the app detects the iPhone is laying flat on its back.

Another option would be to disable the seismic sensor data output when a face is detected with the front facing camera.

Requiring the app to be running in the foreground would also further prevent false readings.

This could easily, quickly, and cheaply create a huge network of seismographs around the world.
