This app downloads the United States Geological Survey (USGS) data on worldwide earthquake activities hat occurred during the past 2 weeks. Every time the app is ran the most recent earthquakes 2.5 and above on the Richter scale are added to the list of earthquakes in real time.

The earthquakes list includes location, magnitude, coordinated universal time ( UTC), latitude and longitude coordinates data.

A map is generated for each earthquake listed in a table view by tapping on a table view row. The map will then be scaled to the general earthquake region, pinpointing the epicenter of the quake with a drop pin symbol. The current location of the iPhone is also shown with a blue circle on the map.

A second view allows for input of latitude and longitude coordinates to visualize associated locations.

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