Induced seismicity in Basel
The largest event prompted concern from local residents. The six borehole seismometers installed near the Basel injection well to monitor the natural background seismicity and the geothermal stimulation recorded more than 13,500 potential events connected with the geothermal project, from which 3,124 were of sufficient quality to permit [hypocenter] determinations in the period 2–12 December 2006, which spanned the main stimulation and the decline in the event rate. During the post-stimulation period from 13 December 2006 onward, a further 350 locatable events were detected up to 2 May 2007, by which time events were occurring sporadically at around one per day. In all, locations for more than 3,500 events were determined.

The largest earthquake in Japan's recorded history struck offshore on March 11, and police found as many as 300 bodies in the north-eastern coastal area that bore the brunt of the tremors and ensuing tsunami. The earthquake struck at 2:46 p.m. local time at a depth of 10 kilometres about 125 kilometres off the eastern coast, and was followed by at least 19 powerful aftershocks.
