20 Years of Eruption at Kilauea and Waiting for Mauna Loa

by Don Swanson,Volcanologist, Hawaiian Volcano Observatory

 

  • Kilauea's Pu'u O'o-Kupaianaha eruption, which began on January 3, 1983, is already the volcano's longest rift eruption in at least 600 years
  • Lava has destroyed 8 miles of highway and 189

    Lava ccean entry and bench collapse...

    The 13-year-old East Rift Zone eruption of Kīlauea Volcano has returned to the steady-state condition that existed prior to the dramatic eruptive surge on February 1st.

    Monday, March 11, marks the anniversary of the last of a series of dramatic collapses at Kīlauea summit. On three occasions in February and March 1960 the floor of Halemaumau Crater broke apart and collapsed inward, raising a roiling black column of steam and rock dust 500 feet in the air.

    I will end my series of these columns with some thoughts about preparedness for future disasters and some personal thank-yous.

    The "Volcano Watch" column first appeared on November 3, 1991. In the last four plus years, the staff and I have written 207 columns covering a wide range of topics, including updates on the ongoing eruption of Kīlauea, hazards posed by that eruption, long-term volcanic and seismic hazards in Hawaii, as well as descriptions of volcanic and seismic events worldwide.

    February 16, 1996

    Kīlauea's 13-year-long eruption restarted on Valentine's day after a nine-day-long pause in activity. The renewed activity began about midnight on February 13 with changes in the ground vibrations recorded near the Pu'u 'O'o vent.

    The staff of the Hawaiian Volcano Observatory (HVO) joined an international team of 25 scientists and technicians from the United States, Japan, and Italy to make the most detailed seismic recordings on Kīlauea Volcano, using the largest total number of seismic instruments ever installed on a volcano.

    On Thursday morning, February 1, Kīlauea Volcano had an intense swarm of small, shallow earthquakes and rapid ground deformation at the summit.

    Today we face the third shutdown of the Federal government since mid-November. The lack of an operating budget, now fully four months into the 1996 fiscal year, which began on October 1, has had a crippling effect on the efficient execution of our responsibilities and programs.

    The eruption along Kīlauea's East Rift Zone continues with little change from past weeks. The lava is transported underground in a tube from the active vents on the flank of the Pu'u'O'o cone to the ocean at Kamokuna along the eastern side of the active flow field.

    The eruption along Kīlauea's East Rift Zone continues with little change. Based on changes in instrumental readings recorded at the Observatory, brief pause in activity began about mid-afternoon on December 14 and lasted until midnight on December 15.

    Although the partial Federal Government shutdown is over for now, the effects of three weeks with a very reduced staff were heavily felt at the U.S. Geological Survey's Hawaiian Volcano Observatory.

    Wednesday, January 3, marks the thirteenth anniversary of the start of the nearly continuous eruptive activity at Kīlauea Volcano. The Pu'u 'O'o-Kupaianaha eruption is the longest-lived and most voluminous historic eruption on Kīlauea's East Rift Zone. The thirteen years of the eruption can be divided into three distinct phases.
