Theme Collections | Planet Labs Imagery

Theme collections are galleries not specifically related to volcanic hazards, processes, research, types, or features. This includes subjects such as different satellite platforms, astronaut photos from the Space Shuttle, specific photographers, or other special collections.


Image Gallery for Planet Labs Imagery

This gallery presents satellite images of volcanoes made available by Planet Inc. (https://www.planet.com/) through a partnership agreement with the Smithsonian Institution. As they note “On average, Planet has 1300 images of every place on earth. This is an unprecedented dataset - we’re creating a global, near-daily stream of satellite imagery that can be fed into a variety of workflows for commercial and humanitarian applications, enabling an ecosystem of apps and services.” The availability of this imagery to GVP, both for this gallery and for describing recent activity in Bulletin reports, benefits the science of volcanology and hazard awareness. There are 372 images available.

This September 2019 Planet Labs satellite image monthly mosaic shows the lobate flow margins and lateral flow levees and margins (N is at the top; this image is approximately 20 km across).

A large unnamed area of recent mafic lava flows is located on the floor of the Ethiopian Rift Valley SW of Tullu Moje volcano. The lava flows were emplaced within a NE-SW-trending zone near the active eastern margin of the rift valley, NE of Ziway Lake (W of this December 2020 PlanetLabs satellite image monthly mosaic, N is at the top). This image is approximately 29 km across.

Beru comprises an area of Holocene basaltic scoria cones and lava flows located along the Main Ethiopian Rift between Fentale volcano to the upper right and Kone to the lower left. Several scoria cones are visible in this November 2019 Planet Labs Satellite image Monthly Mosaic (N is at the top; this image is approximately 21 km across).

Gabillema is situated within the Addado graben and is seen in the center of this November 2019 Planet Labs satellite image monthly mosaic (N is at the top). Lava domes have formed on the flanks and a 5 x 17 km lava field covers the Ado Bad (Ado Lake) Plain, originating from a broad area of vents and cones on the northern side. The crater SW of the summit area is approximately 650 m wide; this image is approximately 52 km across.

Dama Ali is located along the NW shore of Lake Abhe (right) at the southern end of the Kalo Plain, seen in this November 2019 Planet Labs satellite image monthly mosaic (N is at the top). Nested craters are at the summit, with the outermost visible crater reaching around 2 km across. Lava domes have formed along the flanks and the smaller Asmara cone is at the base of the SW flank with a summit crater approximately 800 m in diameter. Darker, more recent lava flows are also visible down the flanks.

Mousa Alli is located on the border of Ethiopia, Eritrea, and Djibouti, and is seen here in this December 2019 Planet Labs satellite image mosaic (N is at the top; this image is approximately 21 km across). The main edifice in the center has undergone extensive erosion and there are scoria cones and lava flows on the SE and NW flanks.

The roughly 40-km-long darker lava flows extending across the center of this December 2020 Planet Labs satellite image monthly mosaic (with N at the top) were produced by the western Manda portion of the Manda-Inakir complex and fill a graben formed through faulting. This complex represents a failed rift segment along the Ethiopia-Djibouti border. Mousa Alli is the edifice to the NE; this image is approximately 80 km across.
