Bagana vent is one of the most active in Papua New Guinea , but it is remote , and so poorly monitored .
situate on the mountainous vertebral column of Bougainville Island , it is both far from any city or declamatory township and is hard to hit due to the rough terrain around it . Satellites are the best manner for volcanologists to keep an eye on the alive top , which has an elevation of 5,741 understructure ( 1,750 meters ) .
A new lava flow was spotted on Bagana volcano by a NASA satellite on May 16.
The vent emits petrol ( admit water vapour and S dioxide ) almost continuously , and frequently spits up boneheaded lava flow .
A lifelike - color image claim byNASA ’s Earth Observing-1 satellite on May 16 reveals a fresh lava menstruation on Bagana ’s easterly flank . Other satellite imaging suggests that the flow was erupted sometime between March 2011 and February 2012 .
The refreshing lava is dark brown , while lighter brown areas were likely stripped of botany by volcanic junk or acid gases . Older lava flows are covered in sluttish green vegetation , and the beleaguer forests are dark immature . The volcanic plume and swarm are both white .
