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.
Peldon
The strongest earthquake to ever strike the UK occurred on the 22nd April 1884. It measured to a 5.1 magnitude on the Richter scale and rendered much of the area around and including Peldon badly damaged. In total, it damaged around 1250 buildings including churches, houses and cottages. It was reported at the time that every single building in Peldon was damaged in some way, including the local church, causing heavy financial ramifications for the local area. The Peldon Rose, the village's 15th century inn, rumoured to have been connected by a smugglers tunnel to nearby Ray Island still exhibits earthquake damage. In 1984 a village festival was held at Kemps Farm, Peldon, to commemorate the 100th anniversary of the earthquake.
