First of all, in the image of Bristol Island a lava field is visible extending towards the west and north-northwest of Mount Sourabaya. The western part looks like it was starting to get frozen over while the north-northwest part of the lava field looks more darker. A steam emission originating from the crater of Mount Sourabaya is also visible. Although the lava appears to retain heat, it is not easy to truly tell whether the eruption has ended all together or if it's still in the last effusive stages.

Meanwhile in the infrared image of Saunders Island, a thermal hotspot is visible inside the summit crater of Mount Michael. This could either mean some low level eruptive activity is taking place, or there's simply high temperatures present inside the crater.
