The U.S. Geological Survey (USGS) has reported 12 earthquakes of magnitude 5 or above during the past seven days, including a strong 6.7-magnitude quake two days ago. The most recent quake was 5.6 magnitude, earlier today (September 18, 2011).

There have been no immediate reports of damage or casualties and no widespread tsunami warning. Just a noticeably active week for earthquakes in Japan, which is located along the Ring of Fire around the Pacific Ocean, a region of the world prone to earthquakes.
