#Volcanoes #Australia #New Three new volcanoes were spotted in southeast Australia; one is 4 million years old and another spits out ash after magma quickly cools. The researchers believe there are likely many more such erupters waiting to be discovered in the area. The researchers from Monash University in Australia discovered the volcanoes by combining satellite images with NASA topography models. The models revealed locations where the distribution of magnetic minerals resembled that commonly found in a volcanic center; this is the center of a volcanos mound, where such minerals and ash are concentrated. Once the researchers located the potential new volcanoes, the team visited the sites to confirm. This technique has already helped to uncover a lot more volcanoes in the area, lead researcher and graduate student Julie Boyce told Live Science in an email. As part of my ongoing research, I have found another 20 probable small eruption centers. I havent driven out to visit most of them yet, though.
