List of earthquakes in 2011
This is a list of earthquakes in 2011. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for some other reason. All dates are listed according to UTC time. The 9.1 Tōhoku earthquake was the fourth most powerful ever recorded and triggered a massive tsunami (around 20,000 deaths). In a very busy year, many earthquakes caused damage in Turkey, New Zealand, Myanmar, India and United States.

Note that an increase in detected earthquake numbers does not necessarily represent an increase in earthquakes per se. Population increase, habitation spread, and advances in earthquake detection technology all contribute to higher earthquake numbers being recorded over time. USGS's Website has more information.
