Eruptions have occurred in 1991, 1998 – 1999 and from 2001 to the present day, with activity being characterised by extrusion of viscous lava forming a lava dome, and occasional larger explosions, forming pyroclastic flows and dusting the areas surrounding the volcano with ash and tephra.

The extent, speed and direction of the avalanche and pyroclastic flows that overwhelmed Johnston, Martin, and others were later described in detail in a paper titled ' Chronology and Character of the 18 May 1980 Explosive Eruptions of Mount St. Helens ', published in 1984 in a collection published by the National Research Council's Geophysics Study Committee.

Eruptions of the Upper Furnas Group were mainly characterised by alternating episodes of magmatic and phreatomagmatic activity producing deposits of inter-bedded volcanic ash and lapilli that overlie the widespread main deposits from the adjacent Fogo volcano.

Eruptions have generally been explosive, and pyroclastic flows and lahars have tended to be directed to the south west by the breached caldera.

Eruptions has also buried numerous lakeside towns by volcanic ash and submerged by rising lake waters.
