Earthquake Lite, a free iPhone/Android app, displays global seismic activity and lists of events that you can filter by location, magnitude, and time, writes blogger Bob Tedeschi.
For example, the app listed nine significant tremors near Japan’s east coast, and one in western China for the week of March 14. You can sort the list according to magnitude, date, and location of the earthquake using free USGS data, and drill down to see the epicenter and more details.
iPhone users of the paid version can receive notifications of any tremor registering 6.0 or more on the Richter scale.

I found two, iEarthquakes and Earthquake, both free iPhone apps. Plus one for just the Bay Area. Of the two, Earthquake lite shows more quakes, but they both show the big ones. There was a 5.1 quake today, (Sunday, March 20) 4979 miles from my current location, for example, near the east coast of Honshu, Japan.
