Paluweh volcano (Flores, Indonesia): major explosion generates ash plume rising to 43,000 ft (13 km) altitude

At least 2000 people were evacuated (from the island?), and no fatalities have been reported. (source: JPNN news)
A large ash plume rising to 43,000 ft (about 13 km) altitude and extending 175 nautical miles to the south was spotted last night by VAAC Darwin. The likely cause is either a major dome collapse triggering a large pyroclastic flow or a vulcanian explosion of the lava dome.
According to the first local press articles, an explosion has occurred last night at 23:36 local time. People from the north coast of Flores (17 km distance to the south) reported having heard rumbling and detonation sounds and seen incandescent lava ejections. A cloud of ash drifted over Flores and deposited about half a millimeter of fine ash in areas of the north coast. People were advised to stay home and wear dust masks.
No reports were found about the situation on Palueh Island itself.
The aviation alert level of the volcano was raised to Red.

The new lava dome on Paluweh Island is still active. A few hours ago, an ash plume, probably generated by an explosion or a small pyroclastic flow, was observed. It is estimated to have reached 6,000 ft (1.8 km) altitude (i.e. about 1 km above the dome), based on visual reports from the Flores coast. ... [more]

For several days, no ash plumes have been observed from the volcano and the thermal hot spot on MODIS hot spot data have decreased. This suggests that the dome growth has slowed down considerably or perhaps even stopped. [more]

Thermal anomalies and an ash plume observed at 12,000 ft (3.7 km) on Friday and Saturday show that the lava dome remains active, and probably continues to produce pyroclastic flows as well. [more]

Thermal anomalies are still visible from Paluweh and suggest that dome growth and pyroclastic flow activity continue, although no recent ash plumes have been observed (most likely because of dense cloud cover). [more]

Paluweh's new lava dome continues to grow. Judging from the distribution of thermal anomalies visible on MODIS imagery, pyroclastic flows have been travelling to the S and SE. Ash plumes have been rising to 8-9,000 ft. [more]
