The subsurface of the East Midlands region has been intensively explored by boreholes and seismic surveys on account of its rich resources of coal and hydrocarbons.
This memoir is based on an exhaustive use of such data, acquired during seven decades of exploration, and aims to present a concise review of the tectonic and sedimentary history of the Carboniferous rocks of the East Midlands region.
It is the fourth in a series of subsurface memoirs relating to Upper Palaeozoic basins, and forms a sequel to a previously published account of the adjacent south-west Pennine Basin (Smith et al., 2005).
On 27 June 2011 a tsunami was reported in South West England, between Penzance and Portsmouth, along approximately 200 miles of coastline.
However, the tsunami was not geological in origin. It was probably caused by a meteorological effect, such as a squall over the ocean developed during summer storms these events are called meteotsunami.

The report utilises the new lithostratigraphical framework, published in the Overview Report which employs the full hierarchy of the stratigraphical code for the correlation of the onshore Quaternary deposits of Great Britain.
It also defines the groups, subgroups and main formations (the principal mapping units). Important members and beds are also described.
The Grímsvötn volcano in south-east Iceland started to erupt on 21 May 2011. The volcano is currently emitting a plume of volcanic ash, which initially reached over 17km but is now declining.
The current eruption was preceded by an increase in seismic activity. The seismic activity and ash plume are being monitored by the Icelandic Meteorological Office .
The London Volcanic Ash Advisory Centre is issuing regular forecasts of the ash plume location, it s currently in the south-east of Iceland .
