Inflation, deflation, Kilauea, Pu'u 'O'o

Above: The common pattern of gradual inflation, followed by abrupt deflation, is well demonstrated by major eruptions and intrusions. Below: Detailed look at a 6-month segment of the tilt record reveals similar inflation-deflation patterns for the high-lava fountaining episodes of Pu'u 'O'o eruption, even though the tilt changes and time intervals involved are much smaller (compare scales of the two drawings). Also well shown are the variation patterns of the two types of earthquakes that commonly precede and accompany Kilauea eruptions.
