활용하고 USGS 지진 데이터를 표시하는 응용 프로그램.
This app uses data from the USGS (U.S. Geological Survey) to display the locations and details of earthquakes on a map of the world. Data can be filtered based on magnitude, and how recently a quake occurred. Optionally, a user can also view simple lists, which can be searched, or listed based on the user's location.
