Basaltic eruptions are often characterized by cyclic changes of activity. At Hawaii, periods of continuous fountaining alternate with much longer periods of effusive outflow1,2. In Strombolian eruptions, activity proceeds through intermittent discrete bursts2–5. We report laboratory experiments that simulate the degassing process in basaltic eruptions. Gas bubbles are generated at the bottom of a tank filled with viscous liquid and topped by a small open conduit. The bubbles rise and accumulate… CONTINUE READING
