The volcano, however, is still erupting. It produces low-level ash plumes, in an often near-continuous fashion. This could suggest that the conduit is currently relatively open and allows magma to rise and degas efficiently without building up large pressure, during deep-seated strombolian activity (webcam images show no or very little glowing material reaching the rim of Showa crater).
