Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Kilauea Volcano Continues to Discharge Lava

Activity Summary for last 24 hours: Kilauea summit and Pu`u `O`o cone continued to deflate. Unusually small amounts of ash and elevated amounts of sulfur dioxide gas continued to issue from the Halema`uma`u vent. At the east rift eruption site, incandescence was observed from vents within Pu`u `O`o Crater; lava flows from the TEB vent flows through tubes to ocean at Waikupanaha; surface flows within the abandoned Royal Gardens subdivision may have reached the coastal plain.

Lava fountain 450 m high bursts from Pu`u `O`o in September 1984. In the foreground, low fountains play above a fissure that opened just before the main vent began to erupt. After the high fountains relieved some of the pressure on the magmatic system, the fissure activity died.

Summary of the Pu`u `O`o-Kupaianaha Eruption, 1983-present

The Pu`u `O`o-Kupaianaha eruption of Kilauea, now in its twenty-fourth year and 55th eruptive episode, ranks as the most voluminous outpouring of lava on the volcano’s east rift zone in the past five centuries. By January 2007, 3.1 cubic km of lava had covered 117 km2 and added 201 hectares to Kilauea’s southern shore. In the process, lava flows destroyed 189 structures and resurfaced 14 km of highway with as much as 35 m of lava.

Beginning in 1983, a series of short-lived lava fountains built the massive cinder-and-spatter cone of Pu`u` O`o. In 1986, the eruption migrated 3 km down the east rift zone to build a broad shield, Kupaianaha, which fed lava to the coast for the next 5.5 years.

When the eruption shifted back to Pu`u `O`o in 1992, flank-vent eruptions formed a shield banked against the west side of the cone. From 1992 to 2007, nearly continuous effusion from these vents has sent lava flows to the ocean, mainly inside the national park. Flank vent activity undermined the west and south sides of the cone, resulting in the collapse of the west flank in January 1997.

Since 1997, the eruption has continued from a series of flank vents on the west and south sides of the Pu`u `O`o cone. During this time the composite flow field has expanded westward, and tube-fed pahoehoe forms a plain that spans 15.6 km at the coast.

    UPDATE:
    VIDEO: Hawaii Volcanoes National Park has a new lava ocean entry – See USGS Video and photo at
    http://www.bigislandvideonews.com/volcano/20090219lavaentry.htm

    February 19, 2009 – Hawaii Volcanoes National Park, Hawaii

    There is a new lava ocean entry from Hawaii’s Kilauea volcano eruption on the Big Island.

    According to the Hawaiian Volcano Observatory, this is the third active ocean entry on the island, and the second active entry to occur inside the National Park.

    It reportedly began within the last day, and has created a small plume and lava delta near the buried Poupou-Kauka West archeological site. The new entry is located between Waikupanaha site (outside of the park) and the more recent Waha`ula entry.
