Delay of Tilt

This graph shows the radial tilt at Uwekahuna (UWE), on the northwest rim of Kīlauea's caldera, and at Pu`u `Ō `ō cone (POC), on the northwest flank of the active vent along the east rift zone, as recorded by continuously operating electronic tiltmeters. Positive changes indicate inflation of the magma storage areas beneath the caldera or Pu`u `O`o. Data are shown for a one-week period. This plot shows the delay in deformation, as also shown in the second animation on
