McDonald Island volcano displays some activity!
"The McDonald Island volcano is unusual because unlike most oceanic volcanoes, it sits on a submarine plateau, which means its eruptions are not as wild and fiery as some - instead producing a slow-moving mass of lava that seeps and spreads," Campbell said."Despite the slow-moving nature of the lava, eruptions over the past 13 years have caused startling changes to the island's geography, obliterating some landmarks and creating new ones."
While people tend to think of volcanoes as destructive, this remarkable natural phenomenon is also productive, creating new land that will make the island more attractive to seabirds, particularly the king penguin."The island is within the Heard Island and McDonald Islands Marine Reserve, one of the world's biggest.Campbell said "almost nothing" is known of McDonald Island "because its uninviting terrain and surrounding hazardous seas make it virtually impossible to get ashore."
