FOUR volcanoes discovered off the coast of Sydney are not at risk of erupting but could hold answers about Australia’s rich mineral deposits, writes news.com.au. The cluster of volcanoes, thought to be about 50 million years old, were found by chance about 250km east of Sydney during a voyage by the CSIRO’s new research vessel, Investigator.
