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.

Mauna Loa 1975 eruption. Lava fountains up to 20 m (65 ft) high erupted from fissures on the north flank of the volcano early Sunday morning, July 6, 1975.

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

Pele continued her march to the sea in the two months since our last eruption update through Volcano Watch. Lava reached the ocean on July 12 and occasionally since then. Also, lava flows were emplaced north and west of Royal Gardens but are not presently threatening any residential areas.

The English missionary, Rev. William Ellis, visited the summit region of Kīlauea 174 years ago this week and made the first written description of eruptive activity at the volcano. His foot party departed Kailua on July 18, 1823, eventually reaching Kapapala on July 30.

The North Kona Coast of the Big Island is fortunate to have several Hawaiian fishponds preserved. These ponds were major construction feats by which Hawaiians cultivated fish.

July 18, 1997

Last Friday, July 18, marked the two-year anniversary of the ongoing eruption of Soufriere Hills volcano on the small Caribbean island of Montserrat. The sulfurous gases, drifting ash clouds, and avalanches of hot rock that periodically burgeon from the volcano have inflicted social and economic hardships that have become increasingly difficult for islanders to bear.

July 11, 1997

Following the June 30th M5.3 Kalapana earthquake, there seemed to be a misunderstanding of what the magnitude of an earthquake really means.

July 10, 1997

A lava flow is nearing the extreme southwest end of Royal Gardens subdivision on the south flank of Kīlauea. 

July 4, 1997

The earthquake that woke many Big Island residents at 5:47 a.m. on Monday, June 30, was the biggest on the island since February 1, 1994, and the largest on Kīlauea's south flank since 1989. Its magnitude (M) was about 5.3 (the exact value is still being refined), big enough to cause extensive non-structural damage in the South Hilo and Puna districts.

June 30, 1997

An earthquake shook the entire Island of Hawai‘i at about 0547 this morning. 

June 27, 1997

Sometimes people call the U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) and ask us if more gas is coming out of the volcano because air quality where they are calling from seems worse, or maybe because the amount of visible fume at Pu`u `O`o or Halema`uma`u seems greater.

A popular local morning radio program had a contest early last week, and the question posed was "Where is the Valley of Ten Thousand Smokes?" Listeners called in with answers ranging from Tennessee to California before the correct answer of Alaska was given.

June 13, 1997

Kīlauea's 14-year-old east rift zone eruption continues. Episode 55, ongoing since February 24, 1997, is characterized by shifting vent locations around the west and southwest flanks of Pu`u `O`o, and by intermittent activity within the Pu`u `O`o crater.

What volcano in the United States has been the most deadly since the country was founded? Mount St. Helens? Mount Rainier? Lassen Peak? Good guesses; but wrong. Don't feel bad, though. Many volcanologists don't know, either.
