Nene goose stands among coastal vegetation

A nene goose, Hawai‘i's state bird and an endangered species, stands among coastal vegetation on O‘ahu island. USGS researchers have tracked nene movements using GPS transmitters to determine where they spend their time and to inform policy and decision making regarding their continued protection under the Endangered Species Act.

PubTalk 12/2002 — Hawai`i's Volcanoes—Never a Dull Moment

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

channelized lava flow forming tube

August 6, 1998 Two weeks later, the same channelized flow has formed a tube. A series of skylights in the roof of the tube forms a chain of orange beads on Pulama pali.

Lava bubble burst explosion on active lava delta, Kīlauea, Hawai‘i

Two bubble bursts explode simultaneously as a consequence seawater mixing with lava in a lava tube beneath surface of a lava delta. Because of the confined conditions in the lava tube, explosive pressures build up as water, heated by contact with molten lava, expands instantly to steam. The explosive energy of the steam is sufficient to blast a hole through the top of the

Cinder Cones on Mauna Kea

Cinder cones at the summit of Mauna Kea. Mauna Kea is a dormant shield volcano on the north end of Hawaii Island. Astronomical observatories in the foreground.

Cinder cones (otherwise known as scoria cones) are the most common type of volcano on Earth. They’re also one of the smallest. They can often be found growing on larger volcanoes, in which case they’re dubbed

The National Science Foundation recently supported a scientific drill hole to examine the long-term growth of a Hawaiian volcano. The objective identified by the principal investigators was to drill through as much as possible of Mauna Kea Volcano and determine the variations in the compositions of the lavas over time.

The eruption on Kīlauea's East Rift Zone is rapidly approaching another milestone as its 11th anniversary takes place on January 3. This column will feature an extended summary of the eruption, which is by far the most long-lived during historic time.

The recent history of Kīlauea has been pieced together from geologic mapping and dating, Hawaiian oral histories, and written observations made following the arrival of Christian missionaries in the 1820s.

All of the events that we experience at Kīlauea—eruptions at the summit and on the rift zones, intrusions of magma that don't reach the surface, earthquake swarms that accompany eruptions and intrusion, and the large earthquakes that accompany growth of the volcano and trigger landslides—are responses by the pile of layered lava to the unrelenting pressure of magma rising from below.

Ten years ago on November 16, residents of Hawai`i were awakened by an earthquake at 6:13 a.m. The earthquake had a magnitude of 6.6 and was located beneath the Ka`oiki Fault Zone between the summits of Mauna Loa and Kīlauea Volcanoes.

November 13, 1993

The eruption from the episode 51 vents has continued without interruption since October 2. The flows crossed the Chain of Craters Road near Kamoamoa in Hawai`i Volcanoes National Park on November 7, covered part of the archaeological ruins and entered the sea during the evening of November 8.

The nearly 11-year-long eruption on Kīlauea's East Rift Zone continues with little change. An active lava pond circulates from west to east inside the Pu`u `O`o cone and produces a bright glow at night. Two vent areas adjacent to Pu`u `O`o are active, although both are now crusted over with cooled lava.

Hawaiian volcanoes pass through a sequence of eruptive stages as they grow. There are three main types of lavas in Hawai`i which erupt during the different stages. These distinct lava types have different chemical compositions and physical properties.

Kīlauea Volcano continues to erupt from the episode 52 and 53 vents on the flank of the Pu`u `O`o cone on the East Rift Zone. For the past several weeks, the lava flow has been confined within a tube system that extends from the vent area to the coast at Kamoamoa.

October 15, 1993

Geologic mapping has come a long way since the first map accurately showing the locations of lava flows on the Island of Hawai`i was published by Stearns and Clark in 1930. A more detailed geologic map of the entire island was produced by Stearns and McDonald in 1946. 

How does East Hawaii get vog?...
October 10, 1993

Over the past several weeks, many east Hawaii residents have noticed the high frequency of days with poor air quality. People traveling on Highway 11 through the Glenwood/Volcano area have encountered such severe bog that they had to turn on their car lights to navigate through the hazy gloom.
