Red hot lava erupts vertically in the air from a cone of black, hardened lava

Low fountain of lava from Pu'u 'O'o, Kilauea Volcano, 1983

Low fountain, approximately 50 meters high, from Pu'u 'O'o on Hawai'i Island's Kilauea Volcano (viewed from the north). Lava issuing from the breach in the northeast rim of the crater produced an 'a'a flow that extended more than 4 kilometers. Eruption episode 8.

100-meter lava fountain, Kilauea Volcano, 1983

Pu'u 'O'o fountain approximately 100 meters high during eruption episode 8 on Hawai'i Island's Kilauea Volcano. Dark clots of spatter land near the base of the fountain, contributing to the growth of the cone. Less dense cinder, visible in the upper right, is carried downwind of the cone.

Lava ball, Kilauea Volcano, 1983

Accretionary lava ball comes to rest on the grass after rolling off the top of an 'a'a flow in Royal Gardens subdivision on Hawai'i Island's Kilauea Volcano. Accretionary lava balls form as viscous lava is molded around a core of already-soldified lava.

Arching fountain of lava, Kilauea Volcano, 1983

Arching fountain of lava approximately 10 meters high issuing from the western end of the 0740 vents, a series of spatter cones 170 meters long, south of Pu'u Kahaualea on Hawai'i Island's Kilauea Volcano (episode 2). Episodes 2 and 3 were characterized by spatter and cinder cones, such as Pu'u Halulu, which was 60 meters high by episode 3.

Forest of lava trees, Kilauea Volcano, 1983

Forest of lava trees resulting from eruption of a 1-km-line of vents east of Pu'u Kahaulea on Hawai'i Island's Kilauea Volcano. The bulbous top of each lava tree marks the high stand of the lava flow as it spread through the trees. As the fissure eruption waned, the flow continued to spread laterally; its surface subsided, leaving pillars of lava that had chilled against

Lava fountains erupting from fissures, Kīlauea, Hawai‘i

Lava fountains erupt from fissures during the first week of the Pu‘u ‘Ō‘ō eruption south of Pu‘u Kahaualea, approximately 2.4 km (1.5 miles) northeast of where subsequent eruptions built the Pu‘u ‘Ō‘ō cone. The early fissures cut through old forested lava flows in a remote section of Kīlauea's east rift zone. Note single 'ohi'a tree burning in front of the fissures.

Submerged coconut grove at Halapē after 1975 quake, Kīlauea

A M 7.7 earthquake on November 29, 1975, was located beneath the south flank of Kīlauea. Along the south coast of Kīlauea at Halapē, 30 km southwest of the earthquake, the ground subsided by as much as 3.5 m (11.5 ft), which left a grove of coconut palms standing in water about 1.2 m (4 ft) deep and the new shoreline about 100 to 150 m (110 to 164 yd) inland from its

Earthquake-damaged road, Hawai‘i Volcanoes National Park, Kīlauea

Ground cracks along Crater Rim Drive in Hawai‘i Volcanoes National Park caused by the M 7.7 earthquake on November 25, 1975. The cracks resulted from slumping of the ground toward the rim of Kīlauea Crater, the edge of which is left of the guardrails.

Seaward sliding of Kīlauea's south flank over many thousands of years has resulted in large ground displacements along shallow faults that break the surface, as shown by the cliffs ("pali" in Hawaiian) seen here. Most of the movement along the faults occur during sudden slip that cause large earthquakes. Scientists recently discovered that the south flank also moves

March 19, 1993

This Thursday marks the ninth anniversary of the beginning of the last eruption of Mauna Loa Volcano, following a nine-year period of quiescence.

March 12, 1993

The eruption on Kīlauea's East Rift Zone continues, with little change from last week. Lava from the episode 51 and 53 vents, both located on the southwest flank of the Pu`u `O`o cone, flowed through lava tubes to the coast.

The eruption on Kīlauea's East Rift Zone continued through the week. Two vents were active, both located on the flanks of the 770-foot-high Pu`u `O`o cone.

February 26, 1993

The 10-year-long eruption at Kīlauea Volcano started up again during the morning of February 16, after a period of inactivity lasting about 10 days. The eruption began at the episode 51 vents on the west flank of Pu`u `O`o, with only small volumes of pasty lava flowing through the pre-existing tubes.

On Monday, Feb. 17, at about 7:30 p.m., lava began erupting from a fissure on the southwest flank of Pu`u `O`o.

February 19, 1993

In February 1877, an unusual eruption occurred on Mauna Loa Volcano. Part of the eruption was submarine, and the eruptive fissure was neither at the summit nor along one of Mauna Loa's well-defined rift zones. 

February 12, 1993

An intense earthquake swarm occurred beneath the upper to middle East Rift Zone of Kīlauea Volcano starting at 11:36 p.m. on Sunday, February 7. At the peak of activity, the seismic network operated by the Hawaiian Volcano Observatory was recording nearly 400 earthquakes per hour.

Earthquake activity this past week was considerably reduced from the high levels recorded the previous week. Three earthquakes occurred that had magnitudes greater than 3.0. The first, a magnitude 3.4, occurred on February 2 at 1:24 p.m. beneath the south flank of Kīlauea Volcano.

Nearly everyone on the island of Hawai`i should have felt an earthquake this past week. As the accompanying map shows, Hawai`i was rattled by 11 earthqukes large enough to be felt in less than four days.

The eruption from the episode 51 vents, located on the west flank of the Pu`u `O`o cone on the East Rift Zone of Kīlauea Volcano, continues with little change. Lava is being fed to the coastline near Kamoamoa through a well-established underground tube system with only a few skylights, through which the flowing lavacan be seen from the air.

One of the main impediments to predicting the future behavior of Kīlauea and especially Mauna Loa Volcanoes is the short historical record of each volcano.
