Have you ever felt something and asked yourself, "Was that an earthquake?" If you live in an area with known fault lines, you're probably already aware of the United States Geological Survey's (USGS) earthquake Web site, earthquake.usgs.gov. If you have an Android device, you can track earthquakes easily with a couple of simple apps.
There are a few earthquake apps for Android devices, but we like Earthquake Alert and Earthquake. They are both easy to read and pull their data straight from the USGS. You can even create alerts so you'll know right away when an earthquake occurs.
For Android smartphones, Earthquake Alert has a slightly better user interface than Earthquake. When you touch a recent earthquake from the list, a set of buttons come up, allowing you to see it on a map, view the details, share it, or go to the USGS Web site.
The Earthquake app looks great on Android tablets. The list of recent earthquakes is on the far left and a large map takes up about three quarters of the screen.
That's it. The next time you get that feeling, you'll be able to use your Android device to quickly confirm whether or not you felt an earthquake. By the way, that 3.6 quake in the San Francisco Bay Area occurred during the writing of this post.
