The World Meteorological Organization (WMO), in collaboration with the International Union of Geodesy and Geophysics (IUGG), the Meteorological Service of New Zealand (MetService) and other partners, is convening the Eighth International Workshop on Volcanic Ash (IWVA-8) at the Energy Events Centre in Rotorua, New Zealand on Saturday 4 and Sunday 5 February 2023.

The workshop will take place in the Skellerup Room ("Breakout 2") - See Floor Plan


Workshop Information

The main objective of the workshop is to demonstrate the worldwide progress made in supporting the scientific and technological advancement within the international airways volcano watch (IAVW) over the past 10 years or more and to highlight where gaps and other limitations in capacity and capability still prevail. The IAVW was established in the 1980s by the International Civil Aviation Organization (ICAO) with the assistance of WMO and other partners and has become a mature, worldwide system comprising meteorological, volcanological, and geological services, and other facilities and services with the objective to support continued safe and efficient aviation operations on the ground and in the air whenever and wherever volcanic eruptions are occurring and/or whenever and wherever volcanic ash clouds and gases are present in the atmosphere.  

Responding to the evolving needs of the aviation industry, the workshop will also look to chart a path for scientific and technological advancement through this decade and beyond, thereby helping to inform the further development of the work plan of WMO Services Commission (SERCOM) Standing Committee on Services for Aviation (SC-AVI) Advisory Group on Volcanic Science for Applications (AG-VSA). 

The intended workshop audience includes meteorological and volcanological scientists, researchers and operational personnel including service providers from volcanic ash advisory centres and State volcano observatories as well as aviation users including flight crew, airport and airspace managers, and airframe, engine and avionics original equipment manufacturers. 

The workshop will comprise a blend of introductory keynote addresses, research and industry presentations including national and regional case studies, and panel discussions with opportunities for audience interaction. Subject to expressions of interest and logistical considerations, a poster session may also be convened.

The workshop is an in-person only event and will be conducted entirely in English.

Preceding IAVCEI Scientific Assembly 

The IWVA-8 workshop will be preceded by an IUGG International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) Scientific Assembly 2023 at the same location (Rotorua Energy Events Centre) from Monday 30 January to Friday 3 February 2023. Information on the IAVCEI Scientific Assembly is available here. Details on other workshops that are proposed to be convened before (pre-) and after (post-) the IAVCEI Scientific Assembly are available here.

iavcei-sa-logoSeveral of the IAVCEI Scientific Assembly sessions are being convened with input from WMO and relevant outcomes will then be carried forward to the IWVA-8 workshop for further consideration. In addition, it is anticipated that the IAVCEI Scientific Assembly with provide aspects such as disaster risk reduction and multi-hazard early warning systems will form key considerations of these sessions.

The president of SERCOM, Mr Ian Lisk, will serve as the lead coordinator of WMO’s input to the IAVCEI Scientific Assembly and then the moderator of the IWVA-8 workshop.
