This area is thought to be a vigorously overturning lava lake, suggestive of a combination of a large mass flux of lava to the lake from a magma reservoir below the surface and a large mass fraction of dissolved volatiles like sulfur dioxide and diatomic sulfur.
This region is believed to be a violently erupting lava lake, implying a mixture of a substantial influx of lava from a magma chamber beneath the surface and a significant portion of dissolved gases such as sulfur dioxide and diatomic sulfur.
