iPad Screenshots


Watch U.S. earthquakes unfold, just seconds after they occur. QuakeTracker displays data from the United States Geological Survey on an interactive map, using pulsing yellow circles to indicate a quake's magnitude. Tilt the map using a two-finger swipe to see the quake's depth. Zoom in to see more detail.

QuakeTracker has two modes. The first is Latest U.S. Seismic Activity. The app downloads data from the previous seven days, then displays any quake measuring 3.25 or greater in a time-lapse visualization, showing the magnitude and depth as each quake hits. The second mode is Top Ten Quakes, which displays the biggest seismic events in the lower 48 states since 1860. In addition to the graphical display, both modes list the time, date, location, magnitude, and depth of the quake.

QuakeTracker originally appeared in an iPad-optimized issue of Popular Mechanics. Check out Popular Mechanics magazine in the App Store, or visit us at popularmechanics.com.

Potentially interesting, but currently useless

Looks cool, but with inability to stop and focus on a specific earthquake makes the ap useless. the timeline advances so quickly, user is unable to learn anything. Will keep the ap loaded for a while with the hope for an update to fix this problem. Won't use again however, until problem is fixed. Still waiting...

Could be better

This app has the potential to be great. Aside from it being a huge ad for popular mechanics magazine, it barrages you with endless annoying popups of recent or historic events. I want to just explore a bit and find out for myself, instead it drives the whole time! Has a map of only the United States and the earthquakes cannot even be clicked on for more information.

Slow it down Guys

Yes, needs a slow down button or a stop feature so you can examine the quake in question. Everyone is telling you this...so I'm not the only one.
But nice idea and thanks for making it free.
