    "abstract": "A model is proposed to explain temporal patterns of activity in a class of\nperiodically exploding Strombolian-type volcanos. These patterns include major\nevents (explosions) which follow each other every 10-30 minutes and subsequent\ntremor with a typical period of 1 second. This two-periodic activity is thought\nto be caused by two distinct mechanisms of accumulation of the elastic energy\nin the moving magma column: compressibility of the magma in the lower conduit\nand viscoelastic response of the almost solid magma plug on the top. A release\nof the elastic energy happens when a stick-slip dynamic phase transition in a\nboundary layer along the walls of the conduit occurs; this phase transition is\ndriven by the shear stress accumulated in the boundary layer. The first-order\ncharacter and intrinsic hysteresis of this phase transition explains the long\nperiods of inactivity in the explosion cycle. Temporal characteristics of the\nmodel are found to be qualitatively similar to the acoustic and seismic signals\nrecorded at Karymsky volcano in Kamchatka.",
