The Asachinskaya group of volcanoes is a complex rounded massif 20x22 km in size and over 300 sq. km, consisting of several volcanic edifises of different ages: the ancient shield-like structure of the Asacha volcano, the cone-shaped stratovolcano Yellow, the relatively young Asacha stratovolcano, a small lava cone Tumanov and a series of extrusions. A feature of the Asachinsky massif is the development within its boundaries of a dense network of tectonic faults in the northeast and northwest directions and arc faults. For example, arc faults with clearly defined displacements are observed on the northeastern slopes of the Yellow volcano.
