Sangeang Api volcano (Sunda Islands, Indonesia): eruption continues, ash spreads to Australia

Eruptions continue at the volcano after yesterday's major explosion. Dense ash plumes rising from the summit crater can be seen on this morning's satellite images, and a MODIS hot spot is visible on the latest satellite data, suggesting fresh magma continues to arrive at the volcano's summit crater.
In the meanwhile, the ash and SO2 plume has drifted and spread over more than 3000 km to the E and SE, covering a vast area that includes parts of northern and eastern Australia. All flights from Darwin airport have been cancelled because of the hazardous ash cloud.
A wealth of photos of the eruption taken from various viewpoints (neighboring islands, boats, in-flight) have emerged on social media and elsewhere. Among other details (i.e. that the height of the plume originally reported by VSI, only 3km) was a large underestimation and is more close to 15-20 km as estimated by VAAC Darwin.
At least 2 pyroclastic flows were produced by partial collapse of the eruption column. This can be seen on pictures taken during the early stages of the eruption. At least one of these flows crossed the shore and continued to travel for about 2-3 km above the sea water (see picture by Sofyan Efendi).
An interesting collection of images can be found at Culture Volcan's post about the eruption.

An eruption warning was issed for Sangeang Api volcano in the Banda Sea (aka "Etna of the Banda Sea"), based on increased seismic activity recorded by PVMBG. No surface activity has been detected so far, but a new eruption from the summit lava dome would not be a surprise. [more]
