East Lae'apuki Shatter Ring (October 16, 2006)
The lava-tube feature seen here is called a shatter ring. Shatter rings are circular to elliptical volcanic features, typically tens of meters (yards) in diameter, which form over active lava tubes. They are typified by an upraised rim of blocky rubble and a central depression.

Gas-Pistoning at Drainhole Vent in Pu'u 'O'o Crater (June 28, 2006)
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.
