1992 February		Aerial (top) and ground (bottom) views of fissure vent and flows on the southwest flank of Pu`u `O`o cone. This was the first lava flow from Pu`u `O`o since the Kupaianaha vent began erupting in July 1986. This vent was active from February 17 to March 3, 1992.
1992 March		Lava that poured from vents of episode 50 and 51 built a shield against the southwest flank of Pu`u `O`o. The shield continued to grow during subsequent episodes.
1992 April		String of spatter cones on the southwest flank of Pu`u `O`o (lower left) formed early in episode 51, which began on March 7, 1992.
1992 April		Lava pond inside Pu`u `O`o crater, the surface of which fluctuated between 35 and 60 m below the lowest point on the crater rim in March and April.
1992 September		Lava tubes developed as flows spread from flank vents of Pu`u `O`o; HVO volcanologists conduct geophysical surveys above lava tubes to calculate lava discharge.
1992 October		Aerial (top) and ground (bottom) views of new fissure on the south flank of Pu`u `O`o cone at the beginning of episode 52. Though quiet when episode 52 began, the episode 51 vents started erupting again on October 3.
1992 November		Pahoehoe flows move across a black sand beach at Kamoamoa and ooze into the sea. By the end of November 1992, flows covered most of the archeological sites, campground, and picnic area.
1993 February		Aerial (top) and ground (bottom) views of a lava fountain and flows on the south flank of Pu`u `O`o cone. This new vent marked the beginning of episode 53. The vent opened about 10 m southwest of episode 52 vents.
1993 March		Lava pond inside Pu`u `O`o was active during the flank eruptions.
1993 March		Lava erupted from episode 53 formed a lava delta at Kamoamoa. Part of the Chain of Craters road is visible on both sides of the new flow.
1993 May		White steam plume at coastline marks an active ocean entry of the Kamoamoa flow field. Note Pu`u `O`o on skyline, about 11 km from the ocean.
1994 March		Several days of spectacular explosions at the Kamoamoa entry produced bursting lava bubbles as large as 10 m in diameter and built two littoral cones on the active lava bench.
