Eruption of Sangeang Api, Lesser Sunda Islands, Indonesia (morning overpass)

Due to elevated seismic activity, the Volcanological Survey of Indonesia issues an alert for Sangeang Api an island volcano in the Flores Sea on May 21, 2014. Sangeang erupted explosively on May 30, sending a thick column of ash and sulfur dioxide billowing into the atmosphere.

The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite captured imagery of the eruption plume the next day. Terra acquired this image at 2:35 UTC (10:35 a.m. local time) on May 31, 2014. Ash drifted southeast, shutting down airports in Bima, Indonesia and Darwin, Australia. Service to Darwin resumed by June 1 as the volcanic activity began to quiet. As of June 4, the Volcano Discovery website reported that eruptive activity continued in the form of low-level ash emissions. The Volcanic Ash Advisory Center (VAAC) Darwin reported a volcanic ash plume was estimated at 10,000 ft (3 km) altitude and extended more than 100 km to the west.

While 13-kilometer-wide (8-mile) Sangeang is uninhabited, dozens of farmers cultivate land on the island. No one was killed or injured during the May 30 eruption, but authorities issued evacuation orders for people within 1.5 km (0.9 mi) of the volcano.
