However, it is not our intention to have detailed sessions discussing environmental concerns, risks and hazards.<\/p>\n<p>Instead, we propose to include a sedimentological sub-theme that has societal significance. In New Zealand\/Aotearoa, the pre-European Polynesian inhabitants (M\u0101ori) who arrived in about 950 AD, have a history of living on an active plate margin and using the geology to survive.
