They are not active anymore though right? Certainly good since it means there is one less thing to prep for.

What they are saying is there is a hotspot under the earth and as the Australian continent moved over it a chain of volcanoes was created. Depending on the thickness of the earths crust volcanoes are created. They think it is somewhere just off TAS - so are looking for evidence of current activity. If you are on mainland Australia they are all dormant with no potential for eruption, as the land has moved will past the hot spot..
The Hawaii chain of island is very similar a hot spot in the molten rock underneath the earth and as the earth and plates move it creates volcanoes and islands in a long chain.

The one that Mount Gambier, SA is built on is not extinct - when I lived there, the Emergency Services all had contingency plans for an eruption. Add Mount Schank about 15km south, and though they are not active, they certainly aren't extinct. Though, i do miss growing my veggie garden there - the soil was amazing!! |
