In cartography and geographic analyses related to volcanoes, especially in Hawaii, there is perhaps nothing more important than having an accurate digital model of topography. Such models depict the three-dimensional nature of the land, elucidating features from past eruptions and influencing potential pathways of future activity.
Famous for glowing red lava and billowing volcanic plumes, Halema‘uma‘u has long inspired poets, painters and photographers to find meaning in the color and light of this dynamic landscape.
The Koa‘e fault system connects Kilauea’s East and Southwest rift zones south of the caldera. Faults here appear as low cliffs, or “scarps,” along Hilina Pali Road in Hawaii Volcanoes National Park. These fault-cliffs slip during major earthquakes, such as those of May 4, 2018 — near the beginning of Kilauea’s 2018 eruption.
Throughout the past two decades, the USGS Hawaiian Volcano Observatory has set up a camera network system to monitor visual changes at Kilauea and Mauna Loa volcanoes. This network was designed for the volcanic activity of the time and captured the two long-lived eruptions of Kilauea at the summit and East Rift Zone up close.
Kilauea’s 2018 summit collapse dramatically transformed the geometry and appearance of Halema‘uma‘u crater and Kilauea caldera.
Last week, Hawaii Volcanoes National Park was able to open the Kilauea Overlook to the public for the first time since the lower East Rift Zone eruption and summit collapse in 2018. The viewing location offers a new perspective on the breathtaking summit collapse structures and the major changes those collapses had on Kilauea’s landscape.
Last week’s “Volcano Watch” article introduced the role of “technician” at the USGS Hawaiian Volcano Observatory. This week, we present the introspective of Steven Fuke’s life (schematic diagram) as an electronics technician at HVO through his experiences, starting with his introduction to HVO.
Mauna Loa, the largest active volcano on Earth, has erupted, on average, every 5-6 years during the past 3,000 years.
Kilauea Volcano attracts researchers from around the world. Johanne “Jo” Schmith joined the ranks of the US Geological Survey’s Hawaiian Volcano Observatory in June to study some deposits of past Kilauea explosions — a timely endeavor given the presence of water in the caldera today.
When you think of GPS, what typically comes to mind? Your phone, the navigation in your car or maybe your watch?
Neither Kilauea nor Mauna Loa erupted in 2019, but this period of relative quiet must not lead to complacency about Hawaii’s two most active volcanoes. Both will eventually erupt again.
On March 30, 2018, a change occurred within the ranks of the USGS Hawaiian Volcano Observatory’s staff when geophysicist Asta Miklius retired. One month later, a collapse at Pu‘u ‘O‘o heralded the start of Kilauea Volcano’s lower East Rift Zone eruption and summit collapses.
About a month ago, I attended the 2019 National Diversity in STEM Conference, an annual meeting organized by the Society for Advancement of Chicanos/Hispanics and Native Americans in Science, put on in Honolulu this year.
During the past two centuries, six lava flows erupted from Mauna Loa’s Northeast Rift Zone and advanced toward Hilo.
In the tradition of Hawaiian Volcano Observatory founder Thomas Jaggar’s innovative field methods, HVO recently used a cutting-edge technique to sample the Halema‘uma‘u water lake deep within Kilauea’s collapsed summit crater.
Information about air quality is important to Hawaii residents, particularly those living on the Island of Hawaii, where volcanic activity can lead to frequently changing environmental conditions.
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.
