U.S. Geological Survey trucks pull off the shoulder of Mauna Loa Observatory Road before dawn.
In late September, East Hawaii residents with ocean views might have noticed an unusual ship — too small for a cruise ship, too big for a fishing boat — sailing just offshore of the 2018 lava deltas along the Puna coast. It also entered Hilo Harbor, where it deployed several smaller boats that canvassed the bay within the breakwall.
The USGS Hawaiian Volcano Observatory detects tens of thousands of earthquakes each year.
The recently published “Geologic map of the central-southeast flank of Mauna Loa volcano” is the culmination of years of field work by the U.S. Geological Survey. This updated map supersedes the “Geologic Map of the Island of Hawaiʻi” (1996) and the “Geologic Map of the State of Hawai‘i” for the Mauna Loa region.
Even though Kilauea Volcano’s lower East Rift Zone eruption has been over for about a year, steam continues to appear in new places or reappear in old places, and vegetation continues to die because of lingering heat and steam in areas of the 2018 fissures.
Volcano observatories throughout the United States work together to ensure efficient and thorough monitoring of the nation’s active volcanoes. This collaboration is particularly evident during a crisis, such as the 2018 eruption of Kilauea Volcano.
This week, a group of volcanic gas scientists from throughout the United States, including staff from the USGS Hawaiian Volcano Observatory, will gather at the Cascades Volcano Observatory in Vancouver, Wash., for a workshop to improve and facilitate collaboration within the volcanic gas community during times of eruption or volcanic unrest.
“Volcano Watch,” weekly articles written primarily by U.S. Geological Survey Hawaiian Volcano Observatory staff and occasionally by USGS partners and university affiliates, was recently honored by the National Association of Government Communicators.
Volcano Watch: New research sheds light on relationship between Hilina fault system and large earthquakes
The pali (cliffs) of Kilauea’s south flank are some of the volcano’s most striking features.
Last month, the entire world celebrated the 50th anniversary of Apollo 11’s triumphant flight to the moon and the first human footsteps on the surface of another planetary body on July 20, 1969.
The slowly deepening pond of water on the floor of Halema‘uma‘u, the first in recorded history, has captured the interest of media and the public, locally and nationally. Many questions are being asked. The two most frequent are where is the water coming from and what is its importance.
The recent appearance of water at the bottom of Halemaumau, a crater at the summit of Kilauea Volcano, has attracted wide attention and generated many questions.
USGS Hawaiian Volcano Observatory scientists usually base their research on observations, either visual or instrumental. Interpretations come from these observations, so they must be as good as possible. Incorrect observations can lead, and have led, to erroneous interpretations.
In ongoing media coverage of demonstrations at the base of the Maunakea Access Road, many hundreds of people can be seen standing on a black lava flow that surrounds the Puʻuhuluhulu Native Tree Sanctuary adjacent to Daniel K. Inouye Highway. That same lava flow continues on the other side of the highway, which traverses the saddle between Mauna Loa and Maunakea.
One year ago, activity on Kilauea Volcano was remarkably different than it is today.
Shortly before midnight July 5, 1975, Mauna Loa Volcano awakened with a shudder.
Hawaii residents are likely familiar with the Volcano Activity Updates that the Hawaiian Volcano Observatory issues for Kilauea and other active Hawaiian volcanoes. These updates, which provide situational awareness of volcanic activity and hazards, were formally established in 2006.
Kilauea Volcano has two rift zones.
Since the early 1990s, scientists have used radar satellites to map movement, or deformation, of Earth’s surface.
The USGS Hawaiian Volcano Observatory, along with its partners at the National Oceanic and Atmospheric Administration’s Pacific Tsunami Warning Center and the National Strong-Motion Project, operates a network of seismic monitoring stations on the Island of Hawaii and throughout the state.
