The Hochstetter Lecturer (named in honour of Ferdinand von Hochstetter - see below) is chosen annually by the Awards Subcommittee. He or she gives a lecture at GSNZ branches during the year on recently completed and largely unpublished findings, and must have a reputation as a good speaker. Send your 2014 nomination to the Awards committee now!
The 2013 Hochstetter Lecturer is Mark Quigley from Canterbury University. Mark will be touring the country during the year (itinerary and lectures below). At University centres the Hochstetter and a Supplementary lecture are given (abstracts below).
About the speaker
Mark Quigley is a Senior Lecturer in Active Tectonics and
Geomorphology at the University of Canterbury (UC) in Christchurch,
New Zealand. He was
appointed at UC in 2008.
Mark was born in London, Ontario, Canada. He obtained his
Honours B.Sc. in Geology at the University of Toronto, Canada (1995-99), M.Sc.
at the University of New
(2000-02), and Ph.D. at the University of Melbourne, Australia (2003-2007). Mark is an active research
scientist with over 40 peer-reviewed scientific articles on topics primarily
related to earthquakes and active tectonics, climate change and landscape
processes. Mark has active research projects in New Zealand, Australia, Tibet,
Iran, Mexico, Timor Leste, and Antarctica. Due to the 2010-2012 Canterbury
earthquake sequence, most of Markís present research is focused in Christchurch
and the surrounding area of the eastern-central South Island of New Zealand.
Mark has appeared in the media several hundreds of times
over the last few years, participating in numerous television programs and
documentaries, and writing articles for the press, science blogs, and popular
science magazines. In 2011 Mark was awarded the New Zealand Prime Ministerís
Prize for Science Communication and the New Zealand Association of Scientists
Science Communication Award for his work in communicating earthquake science to
the public in the aftermath of the Darfield and Christchurch earthquakes. In
2012 Mark founded the SAVVY program for science communication in New Zealand in
collaboration with the New Zealand Science Media Centre. Mark was awarded the
2012 Emerging Researcher Award from the College of Science at the University of
Canterbury and is the 2013 Geoscience Society of New Zealand Hochstetter
Mark presently lives in Riccarton, Christchurch with his
lovely partner Candice Egan and his big fluffy dog Luna.
Geologic and geomorphic impacts of the 2010-2012 Canterbury Earthquake Sequence and local evidence for large prehistoric earthquakes
Abstract: The Canterbury earthquake sequence (CES) started with the 2010 moment magnitude (Mw) 7.1 Darfield earthquake and includes thousands of Mw ≥ 3 aftershocks, most notably the fatal 22 Feb Mw 6.2 Christchurch earthquake. The largest CES earthquakes caused geologic and geomorphic processes that changed the Canterbury landscape. Some of these changes lasted only hours and others will persist in the geologic record for 103 to 106 yrs or longer. Careful documentation of the geomorphic and geologic effects of the Canterbury earthquake sequence and comparing these with instrumental seismic data is important because it helps to define the seismic thresholds for generating these phenomena and it enables paleoseismologists to better interpret these features when they are observed in the geologic record. This talk will summarize the impacts of the CES and show new evidence for the timing, extent, and conditions of prehistoric earthquakes in this region, including penultimate rupture on the Greendale Fault, prehistoric liquefaction in eastern Christchurch, and prehistoric rockfall in the Port Hills south of Christchurch. Better attention to the geologic record will help us to avoid further land planning mistakes and increase societal and financial resilience to future earthquakes both in Christchurch and elsewhere in New Zealand.
The measurement of cosmogenic 10Be contained in rock and sediment can be used to characterise erosion rates on spatial scales ranging from a single outcrop to entire mountain ranges, and temporal scales spanning thousands to millions of years. This is important information when investigating the relative importance of climatic, topographic, and tectonic processes in governing how, and how fast, continental landscapes erode. This talk will present the results from hundreds bedrock erosion measurements from a variety of locations around the planet, including the desert close to the source of the 2010 Mw 7.2 El Mayor - Cucapah earthquake in Baja California, Mexico, actively incising streams in the Southern Alps of New Zealand, and tropical, desert, and cool temperate climate landscapes spanning the entire Australia continent. New predictive relationships between lithology, climate, seismic strain rate and bedrock erosion rate will be proposed for discussion and debate.Itinerary (for more details use the email contacts)

|About Hochstetter by Mike Johnston
Christian Gottlieb Ferdinand von Hochstetter (1829-1884)
Hochstetter was born in Esslingen in the Kingdom of Wurttemberg and joined the Austrian Geological Survey in 1853. Four years later he was appointed geologist on the Austrian frigate Novara that undertook a global scientific cruise. The Novara berthed in Auckland, then the capital of New Zealand, on 22 December 1858. At the request of the New Zealand Government and supported by the Auckland Provincial Council, Hochstetter, accompanied by Julius Haast and others, surveyed the Drury Coal Field to the south of the capital.
This was accomplished so successfully that the provincial council persuaded the commander of the Novara to allow Hochstetter to remain in New Zealand so that he could undertake further work in the province. Over the next five months Hochstetter and Haast, and a support team, visited much of southern part of Auckland Province, including the volcanic region and the gold diggings at Coromandel Harbour.
On completion of his Auckland mapping, Hochstetter was commissioned by the Nelson Provincial Council to report on the mineral wealth of the province. Hochstetter, accompanied by Haast, arrived in Nelson, after brief stops at New Plymouth and Wellington, on 4 August 1859. In Nelson, they examined Dun Mountain, and from which he collected and subsequently named dunite, the Aorere Gold Field and other places of interest. While Hochstetter visited the Wangapeka Gold Field in the west and Lake Roto-it, Haast geologically examined the eastern part of the province . Hochstetter left Nelson for Sydney on 1 October 1859, on the first leg of his return voyage to Europe.
His geological maps of Auckland and Nelson were the first of their kind in New Zealand.
