Overview

The Sedanka lava field (Sedanka Dol) is located immediately west of the Sredinny Range axis and is formed by dominantly mafic lavas from small strato- and shield-like volcanoes, along with more than 100 cinder and lava cones of the late Pleistocene-Holocene age. For this compilation the volcanic field area is considered to be up to 10 km wide and stretching about 25 km from south of Gorny Institute volcano towards the NNW between Tuzovsky volcano to the SW and Titila to the NE. Other workers (eg.

Nekrylov et al. , 2015) define the field to include the eight large edifices from Terpuk on the SW to Shishel on the NE.

Regional Volcanic Activity

The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Several scoria cones on the Sedanka Lava Field are shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 13 km across). The Gorny Institute volcanic complex is to the upper right and the Sredny scoria cone of Tuzovsky is to the upper left, and between them are scoria cones of Sedanka. The field has more than 100 cones across an area of around 10 km.
