What do you know about “Macquarie Island (麥夸里島)”?
The island is still seismically active with frequent earthquakes and landslides as the geological processes continue. The rock exposures on Macquarie Island are remarkable for their lack of deformation and the clarity of the rock sequences from all levels down to 6km below the ocean floor crust.It is recognised on the world heritage list for its wild natural beauty and its phenomenal concentrations of marine life. The vast majority of the site (5,272 km2, 97.7% of its total area) falls within a marine reserve that protects the ocean around the island, supporting some 100,000 seals and 3-4 million penguins. A breeding population of 850,000 pairs of endemic Royal Penguins is one of the greatest congregations of seabirds in the world, while king penguins, four species of albatross and elephant seals are other prominent members of the rich wildlife community.
