Gas-pistoning is an interesting phenomenon seen at Kilauea and other volcanoes. It is caused by the accumulation of gas within, or the rise of a gas slug through, a column of lava. In either case, the gas pushes up the overlying lava (the "piston"). Eventually, the gas breaches the surface and escapes, sometimes as a forceful jet of fume and spatter.

The first priority of any eruption is to assess current status and what might happen next. To accomplish this, Mount St. Helens became one of most heavily monitored volcanoes. At the start of the 2004–08 eruption, 13 permanent seismic stations operated within about 12 miles of Mount St. Helens.

Throughout the eruption, scientists installed monitoring stations to track volcanic activity, deployed temporary monitoring ""spiders"", monitored the temperature of lava spines and created time-lapse of dome growth. During the 3+ years of the eruption, lava piled up to form a new dome 460 m (1,500 ft) high.
