Caption:	Field photos from the Northern Mariana Islands (NMI) hydrophone deployment. Three hydrophones were deployed ~70 miles northwest of Saipan in ~4000m of water on June 20. A fourth hydrophone was deployed on June 17 with all arranged in a diamond shaped array. Work was done off the vessel the Peregrine (Pacific Marine Enterprises) in collaboration with NOAA and with assistance from the NMI Emergency Management Office. The hydrophones will record signals from submarine volcanoes, earthquakes, and other natural and man-made sources for about one year.

Caption:	Timeline of eruptive events at Bogoslof volcano associated with the formation and destruction of the first known subaerial lava dome emplaced during the 2016-17 eruption. The eruption on June 10 destroyed the lava dome that developed June 5-10 and also appears to have destroyed all remaining parts of the 1992 lava dome. The blocks strewn over the surface on the southwest part of the island are likely all that remains of these two lava domes. COSMOS SkyMed compilation by Dave Schneider, USGS-AVO.

Bomb, Maar/tuff cone/tuff ring, Seamount/ submarine volcano

Caption:	Worldview satellite image of Bogoslof volcano collected at 23:13 UTC on June 12, 2017. The circular embayments were formed by a series of more than 40 explosions that began in mid-December, 2016. These explosions have greatly reshaped the island as material is removed and redeposited as air fall. Vigorous steaming is observed from a region to the south of the most active vent areas in the lagoon. Lava extrusion produced a circular dome that first rose above the water on June 5 and grew to a diameter of ~160 m (525 ft) before being destroyed by an explosion early in the day on June 10. Large blocks of the destroyed dome can be seen littering the surface of the island near the lagoon.

Eruption cloud/ plume/ column

Caption:	Landsat-8 image of Bogoslof volcano collected on June 5, 2017 at 2200 UTC (1400 AKDT). This composite image of true color visible and thermal infrared data shows a sediment plume in the ocean that extends from the vent region in the horseshoe-shaped lagoon. Warm water outflow is highlighted in color extending northward from the lagoon where it mixes with colder ocean water. A hot vent just south of the lagoon can be seen in red, and several small puffs of white steam are visible coming from this region.

Caption:	Worldview satellite image collected at 14:34 AKDT (22:34 UTC) on May 28, 2017 showing the initial development of the eruption cloud from Bogoslof volcano. The eruption began about 18 minutes prior to this image and the cloud rose to an altitude in excess of 40,000 ft above sea level. The white color of the eruption cloud is due to the large amount of water that is incorporated into the eruption column as the vent is located in shallow water.
