Lava flow field on Bristol Island on 22 Sep 2016 (image: Landsat 8 / annotated by Culture Volcan)
The latest eruption of the volcano during April - late July 2016 could only be observed from space. An analysis of images taken before, during and after the eruption allows to see a vast field of fresh lava flows.

The eruption on the remote island continues. Recent satellite images show increased ash emissions as well as two dark stripes that likely are newly erupted lava flows to the west and northwest from Mount Sourabaya volcano.
Wed, 13 Jul 2016, 06:00The Buenos Aires VAAC reported that on 19 July a diffuse ash plume from Bristol Island's Mt. Sourabaya was visible in satellite images drifting 30 km NE. A persistent thermal anomaly was also identified in satellite data.

The eruption continues, but seems to have lost energy recently: satellite images still show ash plumes drifting from the remote island, but these have been less intense during the past week.
Wed, 15 Jun 2016, 06:00The Buenos Aires VAAC reported that on 16 June a diffuse ash plume from Bristol Island's Mt. Sourabaya was visible in satellite images rising to an altitude of 1.5 km (5,000 ft) a.s.l. and drifting SE. The report noted low confidence in the plume altitude due to weather clouds in the area.

Wed, 25 May 2016, 06:00According to NASA's Earth Observatory, a Moderate Resolution Imaging Spectroradiometer (MODIS) satellite image of Bristol Island acquired on 28 May showed an ash plume from Mt. Sourabaya drifting NE. Based on satellite image analysis, the Buenos Aires VAAC reported that during 29-31 May gas plumes with possible minor ash content drifted as far as 185 km N, NNE, and SE at an altitude of 1.5 km (5,000 ft) a.s.l.
