We consider the process of slow extrusion of very viscous
magma that forms lava domes. Dome-building eruptions
are commonly associated with hazardous phenomena, in-
cluding pyroclastic flows generated by dome collapses,
explosive eruptions and volcanic blasts. These eruptions
commonly display fairly regular alternations between pe-
riods of high and low or no activity with time scales from
hours to years. Usually hazardous phenomena are asso-
ciated with periods of high magma discharge rate, thus,
understanding the causes of pulsatory activity during ex-
trusive eruptions is an important step towards forecasting
volcanic behavior, especially the transition to explosive ac-
tivity when magma discharge rate increases by a few orders
of magnitude. In recent years the risks have increased be-
cause the population density in the vicinity of many active volcanoes has increased.
