The BGS have published some new analyses on the likely temperatures to be found at borehole depths in Britain between 100 and 1000 m.
Accessing heat from the ground is set to become increasing important as renewable heat plays an ever increasing role in the renewable energy mix.
In a paper, published in the Quarterly Journal of Engineering Geology and Hydrogeology, BGS scientists have analysed 1748 discreet temperature measurements. Expected temperatures at depths below the ground surface of 100, 200, 500 and 1000 m are 13, 16, 24 and 38 °C respectively.
A new supply risk index for chemical elements or element groups which are of economic value
The risk list gives a quick indication of the relative risk in 2011 to the supply of the chemical elements or element groups which we need to maintain our economy and lifestyle. The position of an element on this list is determined by a number of factors which might impact on supply. These include the abundance of elements in the Earth s crust, the location of current production and reserves, and the political stability of those locations.
The risk list highlights a group of elements where global production is concentrated in a few countries. The restricted supply base combined with the relatively low political stability ratings for some major producing countries significantly increase risk to supply. The list highlights economically important metals which are at risk of supply disruption including rare earths, platinum group metals, niobium and tungsten. The list also shows the current importance of China in production of many metals and minerals.

The interactive Anglesey i-Map shows the landforms and sediments and summaries of how the main glacial features (striae, drumlins, meltwater channels) were formed.
The Anglesey i-Map is for school students, geography and Earth science teachers, undergraduates and academic researchers, as well as anyone interested in how the landscape around them evolved.
BGS scientists visited north-east Japan in May and June to study the area devastated by the tsunami caused by the Great Tohoku earthquake of 11 March 2011.
During the most recent trip in June, the BGS team carried out further research on the sediments left by the tsunami, and using high-resolution satellite imagery, will map the area of tsunami flooding in the Sendai area.
The British Geological Survey have detected an earthquake of magnitude 3.9 at 06:59 UTC (07:59 BST) this morning (14 July 2011) located approximately 80 km south-south-east of Portsmouth, Hampshire.
Please fill in our questionnaire to help us study the effects of earthquakes.
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 .
