Paleomagnetic secular variation curve for the past two thousand years. Label dates are mean ages before present (B.P.) or Anno Domini (AD), with gray circles indicating estimated error. Note that the magnetic field changes in declination (horizontal arched lines) and inclination (angled vertical lines) over time.

Two bubble bursts explode simultaneously as a consequence seawater mixing with lava in a lava tube beneath surface of a lava delta. Because of the confined conditions in the lava tube, explosive pressures build up as water, heated by contact with molten lava, expands instantly to steam.

Map shows the location of lava flows from Puʻu ʻŌʻō (unshaded), and Kūpaianaha (dark shaded), and Friday's fissure eruption (light shading) on Kīlauea's East Rift Zone. The inset shows the area of the enlarged flow field map and the locations and magnitudes of all felt earthquakes for the past week.
