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...

Hawaiian Volcano Update: Kīlauea’s South Caldera Quaking, April 11, 2024

This past week, earthquakes on Kīlauea concentrated beneath the south caldera area, though only reached magnitude 2.6 despite the region exhibiting accelerated inflation for 3 weeks. Seismic counts across the whole volcano exceeded 100 events yesterday, similar to the previous cycle peak on March 31st but above the average last week of around 50 events per day. However, these numbers are still low compared to the main pulse of magma intrusion into the Southwest Rift in late January and early February, when over 3,000 events occurred within one week. For now, the volcano continues to recharge a...

STEM and suction solutions at HVO —USGS Volcano Watch

STEM is an acronym that stands for Science, Technology, Engineering and Mathematics. In the educational system, encouraging STEM curriculum prepares students for future careers in STEM fields. In this “Volcano Watch” article, we’ll describe how aspects of STEM are applied at the USGS Hawaiian Volcano Observatory (HVO), using a specific example of field engineering work. Staff at HVO study volcanic processes and associated hazards in Hawaii, with the emphasis and end goal of protecting life and property. The backbone of the observatory is the monitoring network, consisting of a diverse array ...

Hawaiian Volcano Update: Kīlauea Swelling Further

March rounds out quietly on Kīlauea, with relatively few earthquakes this month thus far compared to the end of January and beginning of February. This past week, seismicity continues to cluster in the south caldera and upper southwest rift, with sporadic events still occurring in the lower southwest rift. The south caldera and upper southwest rift area continues to swell, accumulating nearly 25 microradians of ground tilt over the past month, half of that within the last week. However, without an increase in earthquakes, a resumption of surface activity is likely still some time away. Volcani...

Using acoustic signals to identify the start of 2022 Mauna Loa eruption — HVO Volcano Watch

The 2022 eruption of Mauna Loa occurred late in the evening of November 27th. The eruption was preceded by intense earthquake activity about half an hour prior to glowing lava seen on USGS Hawaiian Volcano Observatory (HVO) webcams. How does HVO narrow down the precise time that the eruption started? Remote cameras are critical to confirm eruptive activity but, in many cases, worldwide, views of the activity can be obscured. Clouds, fog or volcanic gas can block views. Or cameras may not cover the eruption site. Hence, HVO and other global observatories establish numerous methods to attempt ...
