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.
The Hawaiian Volcano Observatory is no rookie when it comes to using flight to assist with monitoring Hawaiian volcanoes.
Since the end of 2018’s volcanic activity, USGS Hawaiian Volcano Observatory scientists have wanted to resurvey Kilauea Volcano’s ground surface to document changes brought about by the Puna eruption and summit collapse. Doing so would allow us to more accurately answer questions about the total volumes of erupted lava and summit subsidence that occurred last summer.
May 24 is a notable date in Kilauea Volcano’s history.
During the 2018 eruption of Kilauea Volcano, when fissures erupted and lava flowed in the lower East Rift Zone, many Puna residents were displaced from their homes. We, as a community, watched from the sidelines as the eruption went on, helpless in averting the course of nature.
A year ago, USGS Hawaiian Volcano Observatory scientists and Island of Hawaii residents were in the throes of a historically unprecedented series of events for Kilauea.
With the one-year anniversary of the onset of Kilauea Volcano’s 2018 lower East Rift Zone eruption upon us, USGS Hawaiian Volcano Observatory staff, like many Hawaii residents, are reflecting on this historic event.
May 3, 2019, marks the one year anniversary of the start of Kilauea Volcano’s 2018 lower East Rift Zone eruption.
When a major geologic event occurs, scientists who study such events and the people directly or indirectly impacted by it seek to understand its cause.
The end of Kilauea’s 2018 eruption this past September was accompanied by an enormous decrease in the amount of sulfur dioxide gas (SO2) emitted from the volcano. This led to beautifully clear skies gracing the Island of Hawaii, particularly noticeable on the west side, where the volcanic pollution known as vog chronically collected in past years.
