Hawaiian Volcano Update: Moving Magma Trembles Kīlauea, April 25, 2024

Over the past week, deeper earthquakes increased in frequency 5 to 6 miles below Kīlauea, with shallower quakes in the south caldera still ongoing but spreading to include the nearby East Rift Connector. The deeper activity peaked on April 19, and after slowing for three days has now resumed providing frequent long-period signals that indicate the movement of magma within the volcano, even as the ground surface of the volcano continues to swell. As a result of this heightened state of unrest, the USGS Hawaiian Volcano Observatory began issuing daily updates for Kīlauea on April 20, but the v...

Introducing HVO's new online eruption map — USGS-HVO Volcano Watch

The production of maps to track the progress of ongoing eruptions has long been part of the USGS Hawaiian Volcano Observatory (HVO) mission to inform the public about volcanic hazards in Hawaii. The methods used to collect, interpret, and disseminate map data have been evolving ever since HVO’s founding in 1912, and a digital tool newly available to the public continues that legacy of innovation. The new digital tool is an interactive, browser-based display of map data that can be updated in near-real-time with eruption features, such as lava flows. During the Island of Hawai‘i’s most dramati...

Hawaiian Volcano Update: Kīlauea South Caldera Earthquakes Increasing

Earthquake rates doubled this past week beneath Kīlauea’s south caldera and deeper under its summit, indicating ongoing magma movement and accumulation within the volcano’s underground reservoirs. Overall seismic levels are still low relative to the build-up ahead of prior intrusions and eruptions, and there are no signs of an eruption within the short term as Kīlauea continues to recover from its massive Southwest Rift intrusion on January 31. Recent earthquakes and ongoing ground deformation measured by GPS suggest this recent Southwest Rift pathway remains active and magma is still being ...

Magnetics, magma, and monitoring: new technology for old questions — USGS Volcano Watch

Earth’s magnetic field surrounds us every second of the day, everywhere on the planet. Anyone who has picked up a pocket compass and seen the magnetic needle quickly align itself has seen the action of this ever-present invisible field. But can we harness the magnetic field to forecast volcanic activity? Emerging technology in the field of “quantum” science may aid us in doing so. On a large scale, the structure of the Earth is divided into four main layers: the crust, the mantle, and the inner and outer core. The outer core, which starts at about 1800 miles (2,900 km) beneath your feet and e...

HVO and Collaborators Continue Seismic Surveys Across the Active Volcanoes of Hawaii — USGS Volcano Watch

The Island of Hawai‘i is one of the most seismically active regions in the world. In the last five years, an average of 600-1200 earthquakes per week have been detected by the USGS Hawaiian Volcano Observatory (HVO). This regular rumble of activity across the island can be used to our advantage to assess the hazards that Kīlauea and Mauna Loa volcanoes represent. The permanent HVO seismic network consists of nearly 100 stations located across the island. HVO scientists use these stations to monitor the location and character of seismic activity, paying particular attention to signals that mi...
