Our dear Mike Ross is currently (that was written 5 years ago – editor) at the volcano on Ambrym Island in Vanuatu photographing a documentary. Apparently Ambrym means “Here are yams” in the local tongue.
The volcano is a large shield volcano constructed by alternating layers of pyroclastic deposits and basalt. Around the year 50 AD the volcano had its last large explosive eruption that came short just below a VEI-7 with approximately 65 cubic kilometers of Dense Rock Equivalent being ejected.
The caldera that formed is 12 by 8 kilometers and within it are two large volcanic edifices called Marum and Benbow.
During the last century more cones formed at the highly active volcano. In 1953 Mbuelesi formed, in 1988 Niri (New) Taten formed and in 1989 Niri Mbuelesi formed and Taten reactivated. All of these cones have erupted several times up until now. Ambrym has become famous for its persistent lava lake formations.
The current eruption at Marum has formed a lava lake and Mike Ross is there together with Geoff Mackley to recreate Mackleys famous video of the boiling lava lakes, but this time in extreme high definition movie quality.
I think I will just let the images speak for themselves and I know that I speak for everyone when I say that we are looking forward to the finished movie. A

Addendum: the famous lava lakes emptied during the 2018 eruption. On the image, the fresh lava flows to the southeast were fed through a rift from the lakes. The lava did not reach the coast. The image (taken last week) shows no current activity in the craters.
Addendum: and here are some videos of the Ambrym lava lake
