Well I know that we haven't posted these notes as we have gone, so they are not going to be quite as good as our last ones. But the basic info is here. Ask Mrs O'Hagan for any resources that you need to glue into your book.

This Ahievement Standard is divided into a New Zealand section and an Overseas section (of which you will use the South-West Pacific).

For now, we will just look a New Zealand Exteme Natural Event - Volcanic Erutions.

Case Studies:

1. Mt Tarawera Eruption - 1886
2. Mr Ruapehu Eruption - 1995
