The workshop was held in Tokyo immediately
 prior to 9th World Conference on Earthquake 
Engineering. Two previous workshops have
been held in 1984 and 1986 both with an 
emphasis on seismic building design and 
construction practices. New Zealand and
 China were invited to participate in the
 3rd Workshop which was attended by 17 U.S. 
and 23 Japanese representatives. I was
 privileged to attend the third workshop 
which was organised by the Japan Structural
 Consultants Association. 21 papers were
 presented covering building seismic analysis and design, and comparison of design codes and practices. The conference concluded with a working session which allowed a useful exchange of information. In the notes below I have summarized several items of particular interest to New Zealand practitioners.

In 1974 the Management Committee of the Society authorised the setting up of an earthquake reconnaissance team scheme, whereby a team of suitably experienced observers would be quickly transported to the scene of a damaging earthquake. A sub-committee under Mr. J, P. Rollings was formed and a detailed brief for the scheme was prepared and subsequently adopted by the Management Committee. Following advertisements in the Bulletin and the New Zealand Engineering, a pool of over 35 suitable observers has been formed. Most of the pool are practising civil and structural engineers though a number of specialists, including three architects, have been included. The scheme is now fully operational. At present the team
 organiser is Mr. J. P. Hcllings (Wellington) and his deputy is
Mr. N. D. Bardie (Christchurch). Mr. Rollings is also authorised, 
together with the President, to approve a reconnaissance. It is
intended that all pool members will be issued an Engineering Reconnaissance Manual containing information on the administration and aims of the scheme, the action to be taken following a damaging earthquake and a detailed engineering reconnaissance field guide. The following brief is reproduced from the manual; Section One outlines the aims and administration of the scheme and Section Two, procedures to initiate a reconnaissance. These sections together with a budget sufficient to allow reconnaissance of a large earthquake, have been approved by the Management Committee.

This report describes the observations and preliminary assessments of the members of the Reconnaissance Team of the New Zealand National Society for Earthquake Engineering which visited Kobe, Japan and the surrounding areas following the Hyogo-ken Nanbu earthquake of 17 January 1995. The report covers aspects of the effects of the earthquake on the ground, lifelines, buildings, bridges and other structures, and the community. Lessons for New Zealand are discussed.

Significant developments have occurred in the field of lifelines engineering over the past decade both in New Zealand and internationally. In New Zealand, this period encompassed both the beginnings of lifelines engineering and its development into being an established discipline of earthquake engineering. This paper charts the progress of lifelines engineering during this time, outlines the key achievements and critical success factors and discusses current needs and future developments.

This report on the 21 September 1999 Taiwan earthquake describes the event and its impacts, along with the observations of the New Zealand Society for Earthquake Engineering Reconnaissance Team. The report covers the effects of the earthquake on the ground, lifelines, buildings, bridges, other structures and the community. The emergency management response is outlined, along with the response of the earthquake engineering community. Lessons for New Zealand are presented and discussed.

The Canterbury earthquakes have afforded the author a unique opportunity to view the state of engineering from a different perspective. The development of the Detailed Engineering Evaluation (DEE) procedure and the related activities of the Engineering Advisory Group have required thorough consideration of structural engineering practice. This has extended to an overview of the outputs from the DEEs completed by a wide range of engineers, over a wide range of buildings. From these and more general observations of engineering practice in contrast with that of other countries, a view on the state of earthquake engineering in New Zealand is offered with some thoughts on future direction and development needs.

On 12 May 2008 at 2.28 pm Beijing Time, an Ms 8.0 earthquake occurred in the Wenchuan County of Sichuan province, China. The associated fault ruptured over 240 km on the ground surface. The resulting damage was very severe and widespread, with casualties of almost 70,000, another 18,000 missing and 370,000 injured. The New Zealand Society for Earthquake Engineering reconnaissance team observed the effects and the recovery from this massive earthquake. The team studied the damages caused to the natural and the built environment due to fault rupture, seismic shaking, huge landslides and rockfalls. Maximum shaking intensity of MM XI significantly exceeded design intensity of MM VII for the area. Earthquake induced landslides had a major and catastrophic impact on development and infrastructure in this earthquake. Site selection was demonstrated to be critical. Brittle or non-ductile and irregular buildings performed very poorly especially in a seismic overload situation. Well engineered structures and dams performed well. Lifeline facilities were severely damaged, which resulted in interruptions to key transportation routes, inhibited rescue and recovery operations.
