Northern Lake Abaya Volcanic Field is largely between Lake Abaya in the bottom of this image and the eroded Duguna volcano in the top center of this November 2020 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 52 km across). The majority of the central area is recent lava flows from scoria cones with NNE-SSW-trending faults throughout. Hyaloclastite deposits are just north of this image and the 1.8-km-wide crater NNE of the lake is Chiracha volcano.

지질학적 요약

The Northern Lake Abaya volcanic field consists primarily of small Quaternary cones and basaltic lava flows between Doguna volcano to the north, Chericha to the E, Lake Abaya to the south, and the Hobitcha caldera to the west. The 3.5-km-long rhyolitic dome area immediately SE of the Hobitcha caldera trachytic ridge includes recent obsidian flows from vents at Hako and Salewa Dore (Corti et al., 2013).
