Joint Technical Seminar: Non-textbook Flowslides in Fine-grained Colluvium

Flowslides SeminarDate: 2 December 2014
Time: 6.00 pm 
Speaker: Professor Oldrich Hungr, University of British Columbia, Canada


The name flowslide applies to a landslide that involves liquefaction due to the structural collapse of the soil fabric. Flowslides can be extremely damaging, because they involve sudden failure, high velocity and long runout. They occur during earthquakes, but also often spontaneously, as a result of over-stress of collapse-susceptible soil.

Much of the existing literature dealing with flowslides relates specifically to known collapsesusceptible soil types, including loose saturated sand or silt (loess), or extra-sensitive clay. However, collapsive behavior may occur in a much wider range of soil types. Of particular interest are flowslides that involve previously-disturbed soils (“colluvium”).

This lecture presented several cases of major, fatal flowslides that occurred in colluvium formed by previous slow, ductile landsliding. It appears that softening of the disturbed cohesive soil can dramatically change its failure behavior. Thus, assumptions of ductile failure in a given material, even if backed by previous site experience, may become disastrously incorrect. The most common soils involved in these dangerous flowslides are low to moderate plasticity silty clays and silts. The provenance of the examples is Canada, Western USA, Europe and South-East Asia.

Evening Seminar: Managing very large landslides

Managing very large landslidesDate: 28th November 2014
Time: 6.30 pm – 7:30 pm
Venue: Lecture Theatre 10 (LT-10), 4/F Academic 1, City University of Hong Kong
Speaker: Prof. David Petley


Landslides in high mountain areas, such as the Himalayas and the Southern Alps of New Zealand, have the potential to cause very high levels of damage. In most cases they are so large that it is impossible to mitigate them, such that other approaches need to be developed to manage the hazard.

Managing very large landslidesThis talk focused on three case studies.

  • The first explored the Attabad landslide, which in 2010 blocked the Hunza valley in Northern Pakistan, threatening 25,000 people with a dam burst flood. The presenter was involved in a six month long project to manage the risk as the water level approached the overtopping point, which included the setting up of warning systems and the relocation of large numbers of people.
  • The second explored the Gayari rock avalanche in Siachen, Pakistan, which killed 142 soldiers based at an army camp. The author was involved in a programme of work to find and recover the remains of the victims, all of whom were buried 25 m below rock and ice debris from the landslide.
  • The third examined the threats posed by the Utiku landslide in New Zealand, which is a very large but slow moving slide that threatens a railway and a strategic highway.

In each case the talk examined the threats that the landslides posed and the lessons that can be learnt from their management.

Sharing Session: Towards Chartership

Towards ChartershipDate: 17 November 2014
6.30 pm – 8.00 pm


The Geological Society of London is the recognised UK professional body for Geoscientists and was established with the aim of providing lifelong professional support to geoscientists and assuring high professional standards for the benefit of society. It awards the title of Chartered Geologist (CGeol) to competent professionals and is also licensed by the Science Council to award the title of Chartered Scientist (CSci). In recent years there has been increased recognition of the CGeol qualification in Hong Kong and it now the de facto professional standard by which local geologists working in the construction sector are measured.

Towards ChartershipThis sharing session was aimed at early career geologists, providing an overview of the Chartership system, what it is, why it’s worth pursuing and what’s required in order to obtain recognition as a CGeol. In addition to a general overview of these matters, we also invited a number of experienced scrutineers and recent successful CGeol candidates to share their views and experience on the chartership process during a relaxed, informal discussion session. This session directed attendees to the right pathway towards chartership.

Towards Chartership


  • Brief history of CGeol
  • Motives for getting chartered
  • Eligibility criteria for CGeol
  • Competency requirements for CGeol
  • Getting the right experience
  • Mature Candidates Route for those with >20-years’ experience
  • Introduction to CSci and EurGeol
  • Open Discussion with the scrutineers and fellows who achieved CGeol recently

Structural Controls and Contributions to Orogenic Lode-Gold Deposits;
Including a Case Study of the Young-Davidson Mine, Southern Abitibi Subprovince of Canada

Dr Jason ZhangDate: 4 June 2014
Speaker: Dr. Jason J. Zhang

“If a rock is deformed, its geometry before deformation must have been different from its current geometry. If we want to understand the relationships at a certain stage in the geological history, it is necessary to understand the geometry at that time”.

A structural thinking is always the first priority in studying the mineral deposits of a deformed region.

Dr Jason ZhangAs one of the ‘richest’ areas of the world, the Neoarchean (~2.7 billion years) southern Abitibi greenstone belt (subprovince) is well known for its lithological complexity, polyphase deformation, extensive hydrothermal alteration, and spatial association with world-class orogenic gold deposits. Within the subprovince, intrusion-related, in particular syenite-hosted gold deposits represent a significant type that is poorly understood. Whether the gold mineralization is genetically linked to the syenite intrusions (as in a magmatic model) or structurally associated with the subsequent crustal-scale shear zones remains very controversial.

Dr Jason ZhangThis talk presented the first-hand surface and underground mapping results, based on which we identify multiple generations of auriferous vein arrays. Combined with petrologic, petrographic and isotopic geochronologic data, we attempted to unravel their spatial and temporal relations to the regional polyphase deformational events and the major timing of gold mineralization.

Outputs of this research will help understand other syenite- or small felsic intrusion-hosted gold deposits and guide gold explorations throughout the Abitibi subprovince and other greenstone belts worldwide.



Site Visit to Ninepins

Date: 21 September 2014

The Ninepin Group (Kwo Chau Islands) forms one of the Geoparks in Hong Kong and includes South Ninepin Island, North Ninepin Island and East Ninepin Island, along with several small rock islands.Group on Boat

Amongst the group, the extremely uniform hexagonal rock columns at the North Ninepin are one of the most spectacular landforms and attract thousands of visitors every year.

Ninepins rocksThese columnar jointed volcanic rocks could date back to the age of about 140 million years ago. These rock islands were believed to be formed by a major catastrophic volcanic eruption during which vast amount of volcanic ash were erupted and resulted in building up of thick layers of tuff. When the eruption came to the end, the tuff contracted during cooling. The cooling joints within the tuff formed vertically and gradually became the magnificent rugged landscape we see today.

Dr. Rod Sewell of the Hong Kong Geological Survey kindly agreed to join this trip in order to provide an overview of the geological history of the Ninepins and the supervolcano that led to their existence.

Advances in Terrain Mapping and Analysis for Landslide Hazard Assessment

HKRG Landslide conferenceDate: 22 February 2014

The Hong Kong Regional Group held its second one-day conference, following on from the event on Engineering Geology in Geotechnical Risk Management held as part of the bicentennial celebrations in 2007. The 2014 conference took up the theme ‘Advances in Terrain Mapping and Analysis for Landslide Hazard Assessment’, partly as a means of sharing the collective experience and knowledge gained through the various natural terrain hazard assessments conducted in Hong Kong and geohazard assessments conducted elsewhere in the region, and also as a means of funding a trip to Hong Kong by this year’s Glossop Medal recipient Prof. Jim Griffith, who repeated his Glossop Lecture in the week preceding the conference and also delivered the keynote address at the conference itself.

Overall the conference was a great success, primarily as a result of the hard work of the organising committee led by Dick Martin and also thanks to the high quality of the thirteen papers submitted, twelve of which were presented on the day and several of which can be downloaded below. Over 100 local practitioners and academics attended the event, hosted by the Department of Land Surveying and Geo-Infomatics at the Hong Kong Polytechnic University, and the feedback received on both the presentations given and conference proceedings was extremely positive.

Technical Talk: From geological maps to 3D and 4D models.

Date: 18 July 2013

Maps to ModelsDr Diarmand Campbell presented a technical talk titled "From geological maps to 3D and 4D models - transforming the delivery and relevance of geological knowledge for practitioners".  

Geological Survey Organisations (GSOs) are increasingly replacing geological map outputs, by highly visual,variably parameterised 3D, and 4D, models (deterministic and stochastic). Benefitting from improving software, workflows, and visualisation tools, these deliver geological data and knowledge to practitioners engaged in a range of engineering and environmental decision-making.

Maps to ModelsThe British Geological Survey has embraced the migration from 2D to 3D and 4D in developing a National Geological Model of the UK. This aims to be an accurate, multi-scalar, 3D geospatial model depicting the subsurface rocks and sediments. It draws on vast amounts of borehole and other subsurface data and knowledge (e.g. 2.5 million borehole records), and existing local and regional 3D models.

Life in Extreme Environments and its Application to the Habitability of the Universe 

Date: 13 May 2013

Lecture pictureDr Y. L. Li from the University of Hong Kong gave a lecture on the survival of extremophiles in extreme environments and what this means for life in the Universe.  Extremophiles thrive in ice, boiling water, acid, the water core of nuclear reactors, salt crystals, and toxic waste and in a range of extreme habitats that were previously thought to be inhospitable for life. Knowledge of extremophilic habitats expands the number and types of extraterrestrial locations

that may be targeted for searching a second origin of life.

Albania - Kosovo Highway

Date: 8 April 2013

Nick Koor speaking to groupMr Nick Koor from the University of Portsmouth gave a talk on ”Albania - Kosova Highway” on 8 April 2013 in Hong Kong. The Albania - Kosova Highway is a new transportation link which will ultimately link the Adriatic Sea at Durres to the Pan-European corridor in Serbia. The route takes the road through the stunning scenery of the “Albanian Alps” and highly complex active geology.

The Albanian part of the road was opened in 2010. Nick was employed as a technical advisor for a series of significant slope failures which occurred during the construction of part of the new highway. His talk focused on these failures highlighting the geological issues, such as the inadequacy of the site investigation.
