Conditions for magma ascent and pressurization because of passive degassing.
(A) Critical depressurization 
of the shallow reservoir versus the dike half-thickness B for three scenarios:

(red); 
km,

(blue); and 
km, 
, 
(purple). (B) Unplugging (
) and solidification (
) timescales for the same scenarios of panel (A). To determine
