Plumes from Paluweh and Batu Tara, Lesser Sunda Islands, Indonesia

Explosive eruptions continued at Indonesia’s Batu Tara and Paluweh volcanoes throughout April, 2013. On April 16 Volcano Discovery reported that the Batu Tara volcano emitted an ash plume which rose to 7,000 feet (2.1 km). Meanwhile, at Paluweh, the lava dome continued to collapse, with explosions accompanied by rockfalls and pyroclastic flows. An ash plume rising to 7,000 feet (2.1 km) and drifting 20 nautical miles east was reported on April 16 from this volcano, as well. Similar plumes were reported from both volcanoes again on April 20.

The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the region on April 19 and acquired this true-color image of the ongoing activity. Through broken clouds, both volcanoes can be seen emitting wispy plumes which blow to the northwest.

A red hot spot can be seen on Palu island, marking the Paluweh volcano’s explosive caldera. A wispy plume can be seen curling from the summit and over the Flores Sea. To the east, a brighter, straighter plume can be seen pouring from Batu Tara. As of April 23, both volcanoes continue to actively erupt, with frequent explosions and emissions of gas and ash plumes.
