About it

Every day the U.S. Geological Survey publishes the earthquakes it has located around the world. This globe, in the true colors of NASA's Blue Marble pictures, reads its feed when the splash opens: each dot is a quake, bigger for a stronger one, colored by depth (red and orange shallow, yellow and green deeper, blue deepest). Most lie along the edges of tectonic plates, such as the Pacific's Ring of Fire facing you.

Tap the globe to play the quakes in time order: each flashes at its moment. Tap the plaque to fetch the feed again; it shows when the data was fetched. Pick the past week, the past month or a year of the catalog in the Splash tab. If the feed can't be reached, the splash shows a saved snapshot and says so. Nothing is stored or sent.

Details

Splats: Opens at 200,000 at Mid Detail, 210,319 at Low, and up to 1,000,000 at Max
