NEXT WEEKS EVENTS
4th to 10th June 2018
THE FOLLOWING IS AN EXTRACT FROM BRISTOL AND WEST COUNTRY GEOLOGY CALENDARS
MORE DETAILS CAN BE FOUND IN THE BRISTOL AND THE WEST COUNTRY CALENDARS AND ON THE WEB SITES OF THE RELEVANT SOCIETY OR ORGANISATION.
MONDAY 4th
Dave Green - Planetary Geology
When
Mon, 4 June, 19:30 – 21:30
Description
Planetary Geology. Monday 16th April, for 10 weeks, until 9th July (not 7th nor 28th May). The state of knowledge of the planets of the solar system has improved vastly in the past 40 years as a result of space missions and improved technology for observation and analysis. The course will examine the results of this activity and evidence for these interpretations in terms of the internal structure, magnetism and geophysics of these bodies; their tectonics and volcanism, the effects of impacting bodies, and the surface conditions –atmospheres, oceans, sedimentary features and biology. Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £70.

Description
Subduction zone earthquakes and tsunami – exploring the Sumatra subduction zone (the source of the 2004 Indian Ocean tsunami) using marine geology and geophysics and ocean drilling
Lisa McNeill - Ocean and Earth Science, National Oceanography Centre Southampton, University of Southampton
The 2004 magnitude 9.1 earthquake and resulting tsunami originated on the subduction zone margin offshore North Sumatra (part of the Sunda subduction zone system). The resulting tsunami killed more than 200,000 people, devastating large coastal regions around the Indian Ocean, in particular in North Sumatra (Aceh) and Thailand.
Since the earthquake, a large number of countries, in collaboration with Indonesia, have invested in collection of geological and geophysical data in order to better understand the structure of this subduction zone and its potential for large earthquakes and tsunami. The data are also important for a general understanding of these processes and of other subduction zones worldwide. The UK has played a significant role in this effort. This talk will show some of the results of data collected in projects over the last few years, including those led by UK scientists. This includes marine geophysical data that images below the seafloor to show the structure of the subduction zone and the properties of the faults that move and generate the earthquakes. Sediment cores sampling the upper few metres below the seafloor have also been collected to see where submarine sediment flows were triggered by the earthquake shaking in 2004 and in previous earthquakes.
Finally, in 2016, an expedition of the international Integrated Ocean Discovery Program (IODP: scientific ocean drilling) drilled the sediments coming into the subduction zone. These sediments, which originate from the Himalaya and Tibetan Plateau, form the tectonic plate boundary fault – their properties ultimately control the behaviour of the fault. Drilling and sampling of these sediments has now provided information about the properties of the fault zone and why it generated such a large earthquake and tsunami.
