Abstract Abstract Next year will be a notable one for New Zealand earth scientists. Besides the triennial New Zealand Science Congress of the Royal Society of New Zealand (Auckland, February), there will be held in this country several meetings of international organisations closely associated with geology and geophysics. These include the Third World Conference on Earthquake Engineering in January, part of the Eighth Commonwealth Mining and Metallurgical Congress (in Wellington in April, after meetings in Australia), and a Symposium of the International Association of Volcanology (Auckland and Wellington, November and December). The year 1965 will also see the initiation of UNESCO'S International Hydrological Decade, and has been designated by the United Nations as an “International Cooperation Year” in which scientific organisations (among others) have been invited to take part.
