NORTH EASTERN GEOLOGICAL SOCIETY Newsletter January 2012 Dear Member, Our thanks go to John Smith who resigned as chair in December. He took on the post of Chairman following the stepping down of Gordon Wilkinson in 2008. John stepped into the post even though he is not a geologist as an interim measure to ensure the continuation of the Society. Over a number of years he stoically carried on as chair until a new appointment could be made. We are extremely grateful to John for all he has done for the Society through the years, both as Secretary of the Society and latterly as Chair. John has many outside interests, and we would like to thank him for all the time he has loyally given to NEGS in spite of a busy life. 1. NEGS AUTUMN/WINTER LECTURE PROGRAMME. 2.

NEGS AUTUMN/WINTER LECTURE PROGRAMME The December lecture was given by Prof. Richard Davies, Univ. Durham: The Lusi mud volcano disaster, Indonesia: Why and what next? Gordon Liddle has kindly produced this summary of the lecture. Professor Davies delivered an articulate review of the 2006 Lusi eruption of mud in Java for the NEGS members. Using the example, he developed our awareness of the risks associated with the recovery of fossil energy. The ongoing Lusi eruption now covers 7 sq.kms and has been responsible for death, displacement of thousands of local inhabitants and the loss of their homes. The cause of the eruption might be due to the drilling process. The area sits on Pliocence deposits of mud and volcanoclastic material; this lies above a limestone aquifer. Sedimentation of the near surface rocks was rapid limiting normal lithification / diagenetic processes; this allowed water to remain in the sediments. It is possible that the aquifer was breached by the drilling and water pressure increased, exceeded that of the confining rocks, leading to their fracture and eventual eruption of the mud. One projection proposes a 26 year life for the eruption. Prof Davies summarised the possible factors that may have played a part in the disaster and highlighted the global effort of individuals to monitor and interpret the disaster. Discussion and questions explored how the understanding of Lusi might inform the present ‘Fracking’ (i.e. hydraulic fracturing of rock to aid recovery of gas) proposals in NW England Images and additional information are available at the following web sites: Lusi Mud Volcano, Indonesia : Image of the Day earthobservatory.nasa.gov/IOTD/vi ew.php?id=42526CachedSimilar Mud Volcano In Java May Continue To Erupt For Months And ... www.sciencedaily.com/releases/20 07/01/070123181953.htm If you don't have a computer, go and check it out at your local library.
