We invite presentations on:

Complex fault ruptures on transpressional plate boundaries (Conveners: Tim Stahl & Russ Van Dissen): The M7.8 2016 Kaikoura earthquake ruptured >10 faults, spanning multiple tectonic domains and a range of slip rate faults, making it one of the most complex fault ruptures documented globally. This topic will cover insights into earthquake behaviour in transpressional plate boundaries gained from the 2016 Kaikoura earthquake, and from the historical and paleoseismic records in similar plate boundary settings worldwide. We also welcome contributions that consider interactions between upper plate faults and subduction interfaces.

Earthquake geology contributions to seismic hazard analysis (Conveners: Pilar Villamor & Stéphane Baize): Seismic hazard relies on the characterisation of earthquake source parameters. This topic will concentrate on advances in the application of geologic data for Probabilistic Seismic Hazard Assessment, such as: recent efforts to develop comprehensive faults source models; time-space dependent probability models, and surface fault displacement hazard estimation. We particularly welcome contributions covering recent fault ruptures, including the Kaikoura (New Zealand), Amatrice (Italy) and Kumamoto (Japan) earthquakes.

Advances in paleoseismic techniques from high resolution topography, shallow geophysics and dating (Convener: Jamie Howarth): The availability of high resolution topographic data (Lidar, photogrammetric methods, Structure from Motion) is producing many innovative studies on tectonic surface deformation. Shallow geophysical techniques are increasingly being employed to complement traditional paleoseismic techniques, particularly in areas of slow deformation rates, Quaternary dating techniques and improved age modelling has led to a variety of useful insights into fault behaviour over timescales of 100s to 10000s of years.  This topic focuses on recent advances in paleoseismology using high resolution topography, shallow geophysics and/or dating. We also welcome contributions that discuss and evaluate techniques of rapid high resolution topographic data collection and analysis in major earthquake event response situations. 

Large earthquakes in mountainous regions and landscape response (Convener: Phaedra Upton): The Kaikoura earthquake, which triggered ~100,000 landslides, demonstrated the capacity of large earthquakes to dramatically alter the landscape of mountainous regions and their associated lacustrine, floodplain, and submarine environments. This topic will cover paleoseismic studies from active faults in mountainous regions of the world, with a focus on the landscape response that large earthquakes produce and how we can use off-fault geomorphology and sediment records to constrain earthquake hazard.

Earthquake behaviour of high slip strike-slip faults (Convener: Ursula Cochran): Long and detailed records of paleoearthquakes on high slip rate strike-slip faults have been developed around the world, e.g. Alpine Fault, San Andreas Fault, North Anatolian Fault, Dead Sea Transform. Focus will be given to the development of paleoseismic records on strike-slip faults, and insights into plate boundary earthquake behaviour.

Archaeoseismology (Convener: Nicola Litchfield): Archaeoseismology is the study of past earthquakes using indicators left in the archaeological record, and it can be a critical bridge between historic instrumental and pre-instrumental earthquakes, and paleoseismology. We welcome contributions that provide new insights into seismic hazard from archaeoseismological methods.

Studies on other topics related to earthquakes geology, such as paleotsunami, coastal deformation, and seismically triggered mass movements are also welcome.
