The origin(s) of volcanic ash deposits on the Hawaii Island have been an enigma, especially those found on and between Kilauea and Mauna Loa. We know that ash is from explosive eruptions, but the question has been from which volcano?
Portulaca sclerocarpa (also known as Ihi makole) is a critically endangered small succulent plant in the purslane family (Portulacaceae). It only occurs on Hawaii Island and on a small islet off the coast of Lanai. It can be found in various sites in Hawaii Volcanoes National Park, including the Puhimau thermal area.
The U.S. Geological Surveys Hawaiian Volcano Observatory recorded a magnitude-4.2 earthquake beneath Kilauea Volcanos south flank on Sunday evening.
When I was 7 years old, I won my countys earthquake safety poster contest. I remember going to a special award luncheon with the mayor, who complimented my work and gave me an Earthquake in a Can toy. Little did I know how much that event would influence my life.
The long-closed Thurston Lava Tube in Hawaii Volcanoes National Park could reopen within a month if a final repair project goes smoothly.
As many residents of the island of Hawaii can attest, volcanic gases can stinkliterally. But for those of us at the USGS Hawaiian Volcano Observatory (HVO) who are lucky enough to study those gases, our jobs are actually pretty amazing.
HILO On March 30, 2018, a change occurred within the ranks of the USGS Hawaiian Volcano Observatorys staff when geophysicist Asta Miklius retired.
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 (SACNAS) and held in Honolulu this year.
HILO Over the last two centuries, six lava flows erupted from Mauna Loas Northeast Rift Zone and advanced toward Hilo.
HILO In the tradition of Hawaiian Volcano Observatory founder Thomas Jaggars innovative field methods, HVO recently used a cutting-edge technique to sample the Halemaumau water lake deep within Kilaueas collapsed summit crater.
HILO 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.
HILO As roads are recut into Kilaueas 2018 lava flow field, many have been surprised at how hot the lava remains under the surface, even though it is solidified. Why is it still so hot? The short and simple answer is that lava insulates itself very well.
U.S. Geological Survey trucks pull off the shoulder of Mauna Loa Observatory Road before dawn. I park the Jeep at the helicopter staging area, a flat rubble strip flanked by aa lava. The air is cool and thin at 10,000 feet altitude. Our field crew of six from Hawaiian Volcano Observatory (HVO) keep warm unloading gear. We clear the landing zone for the inbound pilot. We organize packs, tools and equipment by checklist for the helicopter.
HILO In late September, East Hawaii residents with ocean views may 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 (HVO) detects tens of thousands of earthquakes each year. Currently, one of the most active areas of seismicity is Kilaueas lower Southwest Rift Zone. This area produces numerous deep earthquakes, mostly at depths of 5-25 miles beneath the town of Pahala and extending about 6 miles offshore.
ALEUTIAN ISLANDS, ALASKA Volcano observatories across the United States work together to ensure efficient and thorough monitoring of the nations active volcanoes. This collaboration is particularly evident during a crisis, like the 2018 eruption of Kilauea Volcano.
