‘Remote Monitoring of an Urban Mud Volcano’
Dr Andrew Hart, Chief Engineering Geomorphologist at Atkins
‘On 29 May 2006, a mud volcano erupted in the Sidoarjo regency of East Java, Indonesia. Unlike other mud volcanoes, this one has been erupting almost continuously since then, burying villages, factories and farmland to now cover an area of almost six square kilometres. Atkins has been monitoring and assessing these risks since early 2007. This work has included using a combination of remote sensing techniques to map and monitor the growth of the mud volcano as well as ground surface movements and deformation around the mud volcano area. To date, the remote sensing work has shown that while the flow of mud from the crater area is now being constrained by the earth embankments surrounding the mud volcano, the ground movements are effecting a much larger area, and are potentially also being heavily influenced by anthropogenic factors. This presentation will provide an overview of the ongoing eruption and how it has developed since 2006. It will also highlight how the use of remote sensing mapping techniques has allowed for the risks posed by the eruption to be monitored over an extended period of time in an innovative but cost-effective manner, as well as the importance of field verification in such work.’
Dr Andrew Hart is a Chief Engineering Geomorphologist working for Atkins, where is also the Discipline Lead for Engineering Geomorphology, Geohazards and Ground Modelling. Andrew has over 23 years of experience assessing the impacts of Geohazards and other geo-engineering constraints while working on a wide variety of infrastructure projects. This has included O&G pipelines and facilities, iron ore railways, highways and mountain roads and offshore wind farms, as well as Geohazard Assessment and Disaster Risk Reduction projects. This means that Andrew has been lucky enough to work in many interesting parts of the world, with a wide range of client organisations and project teams.

‘The Evolution of the Iceland Plume‘
Prof Nicky White Dept of Earth Sciences, University of Cambridge
The mantle plume beneath Iceland is highly unusual: instead of the typical dome-shape at its top it has a number of fingers that stretch as far away as Scotland and Norway, over 1000 km away. The talk will explore the reasons for the existence of these fingers and also the influence they have on the geography of Scotland and Norway.

‘A word on the Anthropocene‘
Prof Philip Gibbard Dept of Earth Sciences, University of Cambridge
Since human activity has undoubtedly left its mark on Planet Earth, especially since the Industrial Revolution, it has been proposed that a new epoch should be added to the currently accepted geological timeline: the Anthropocene. To justify the introduction of this new epoch, a global signature marked by biotic, sedimentary and geochemical change would need to be found, which would show the Anthropocene to be distinctly different from the Holocene. This talk will examine what evidence for the Anthropocene has so far been put forward, and will ask the question whether it is at all possible to identify a specific point in time as the beginning of the Anthropocene.
Phil was awarded the Digby McClaren medal at the International Commission on Stratigraphy’s STRATI 2019 Congress in Milano, Italy on 4 July 2019. The Digby McLaren Medal is awarded to honour a significant body of internationally important contributions to stratigraphy sustained over a number of years. Hear his thoughts on the Anthropocene and its place in our consideration of stratigraphy.

‘The First Day of the Cenozoic: Insights from the Chicxulub Crater‘
Dr Auriol Rae, Dept of Earth Sciences, University of Cambridge
66 Million years ago, a 14 km-diameter meteoroid struck the the Earth at approximately 20 km/s. This event had a profound influence on the history of life on Earth, and produced the 200 km-diameter Chicxulub Crater, located in present-day Mexico. This talk will look at the geological, climatological, and biological consequences of the K-Pg impact, with particular insight from IODP drilling of the crater in 2016. Furthermore, the wider significance of impact crater formation as a planetary geological process will be discussed.

‘Île De La Réunion: Pitons, Cirques, Ramparts and Volcanoes‘
Steve Thompson
Île De La Réunion sits atop its very own, Indian Ocean, Hot Spot, being the top of two massive mid-ocean volcanoes, the dormant Piton des Neiges and the very active Piton de la Fournaise. Piton des Neiges has undergone caldera creation and subsequent collapse and, aided by the wet tropical climate, severe erosion, to produce a stunning topography of Pitons (Peaks), Cirques (steep basins), and Ramparts (near vertical crater walls). Le Parc National de la Réunion, which encompasses both volcanoes and covers 42% of the island, was elevated to World Heritage Status by UNESCO in 2010.
