Geologist Frank Trusdell will talk about the historic 2022 eruption of Mauna Loa and what we’ve learned from it.

Activity from the latest Kīlauea eruption is concentrated in a large lava lake in the eastern half of the summit crater and a smaller lake to the west.

Newberry Volcano has been active for more than 530,000 years, most recently 1,300 years ago and is designated as a “very high threat” volcano by the U.S. Geological Survey.

In the past 5 years, the average weekly number of earthquakes has increased from about 60 to 600 per week under Pāhala, the Big Islandʻs most seismically active area.

While eruptions can be spectacular to watch and experience, they provide a stark reminder of how life on the Big Island can be impacted very quickly by volcanic activity.

Real-time views of an eruption site are a vital source of information for emergency managers, so webcams are one of the most important tools in an eruption crisis. HVO maintains a network of continuously operating webcams across Mauna Loa and Kīlauea.

The flights are to survey and control invasive Guinea grass and fountain grass in some areas of Hawai’i Volcanoes National Park.

This new Kīlauea eruption is viewable from almost all open areas around the caldera in Hawaiian Volcanoes National Park, but there are some parts of the park that are closed to protect breeding and nesting nēnē.

The new eruption of the volcano that ranks among the world’s most active began shortly after 4:30 p.m. Jan. 5.

Kīlauea’s summit eruption continues and is confined to Halemaʻumaʻu crater within Hawai‘i Volcanoes National Park.

Lava flows have inundated much of the crater floor, which is nearly 300 acres.

The team of inspectors will examine the damage and impact sustained to the Mauna Loa Observatory Road and other infrastructure that were overrun by lava from the eruption on the Big Island.

The earthquake was at a depth of 12 miles below sea level; and it occurred in a region of stress interaction between Mauna Loa and Kīlauea volcanoes.

Years of restoration work and ungulate control efforts in the Pu‘u Maka‘ala Natural Area Reserve could have been undone had lava flows gone a different direction.

There are as many different specialties within volcanology and as many paths you can take to get there as there are tools of the trade.

A new University of Hawaiʻi collaborative study by a team of experts estimates vog (volcanic smog) will have detrimental impacts on student test scores, especially students on the Big Island.

Often, the earliest signs of volcanic unrest, before lava is seen, are provided by earthquake activity occurring deeper within the Earth than where other volcano monitoring capabilities can reach. 

During the workshop, the agency will gather public input for the state’s update to its Hazard Mitigation Plan that deals with flooding, hurricanes, wildfires and other hazards.

A week ago, the Hawaiʻi Volcanoes National Park released a Finding of No Significant Impact on the plan to move forward with the park’s Disaster Recovery Project following the 2018 eruption and summit collapse of Kīlauea volcano.
