The deepest known volcanic eruption, and thus a strong contender for the "deepest volcano" by activity, is on the Mariana back-arc, discovered in 2018 at depths of 4,050–4,450 meters (around 14,700 feet) below the Pacific Ocean, making it the deepest recorded eruption ever. Before that, West Mata volcano, near Tonga, was famous for the deepest eruption filmed (around 1,200m/3,900ft) and its extremely hot lava.
The West Mata volcano is ~1200 meters (~4000 feet) below the surface of the ocean, where cameras captured the deepest ocean eruption ever found.
Yellowstone Caldera activity remains at background levels, with 79 located earthquakes in December (largest = M2. 7). Deformation measurements indicate subtle uplift along the north caldera rim that appears to have started in July.
The long history of volcanism at Mount Mazama, the volcano that houses Crater Lake, suggests that this volcanic center will be active in the future. Future eruptions will likely occur within the caldera and probably beneath the water's surface.
WORLD´S LARGEST VOLCANIC REGION DISCOVERED IN ANTARCTICA
Experts have discovered as many as 91 volcanoes under Antarctic ice, the largest of which is as high as Switzerland's Eiger volcano, rising 3,970 meters above sea level.
Yellowstone's famous caldera, which last went off more than 640,000 years ago, can lay claim as North America's most well-known supervolcano. But it isn't the continent's largest — a more ancient one found near the small southwestern Utah town of Enterprise, was about 30 times bigger.
Aircraft flights in which he served as a navigator and expedition leader crossed the Atlantic Ocean, a segment of the Arctic Ocean, and a segment of the Antarctic Plateau. He is also known for discovering Mount Sidley, the largest dormant volcano in Antarctica.
Volcano field on Kruzof Island with Mt. Edgecumbe, Crater Ridge, and several smaller cones. After about 800 years of "dormancy" at Mount Edgecumbe, researchers observed hundreds of small earthquakes in April 2022.
The Cleetwood Cove Trail, the only access to the lake is closing until approximately 2029 for repairs. We decided to last minute to visit the park before the trail closure. The park will remain open. We did the 5hr boat tour and spent 3hrs on the island.
The model shows that the fallout from a Yellowstone super-eruption could affect three quarters of the US. The greatest danger would be within 1,000 km of the blast where 90 per cent of people could be killed. Large numbers of people would die across the country – inhaled ash forms a cement-like mixture in human lungs.
This comes out to an average of about 725,000 years between eruptions. That being the case, there is still about 100,000 years to go, but this is based on the average of just two time intervals between the eruptions, which is meaningless. Most volcanic systems that have a supereruption do not have them multiple times.
The hot springs at Yellowstone National Park have injured or killed more people than "any other natural feature" there, according to the National Park Service. As you might imagine, the damage is usually caused by entering or falling into the boiling thermal waters.
The Taftan volcano, located in Southeastern Iran, which has been classified as dormant for the last 700,000 years has begun to show signs of life. The 13,000 foot summit has risen around 3.5 inches from Jul. 2023 to May 2024.
Yes. Encounters between aircraft and clouds of volcanic ash are a serious concern. Jet engines and other aircraft components are vulnerable to damage by fine, abrasive volcanic ash, which can drift in dangerous concentrations hundreds of miles downwind from an erupting volcano.
1. Mount Vesuvius, Italy. Located near Naples and close to densely populated areas, Mount Vesuvius is infamous for the catastrophic eruption that buried Pompeii in 79 C.E. Today, millions live within its immediate area. With explosive eruptions and deadly pyroclastic flows, Vesuvius remains a top threat.
On 9 December 2019, the volcano on Whakaari-White Island near Whakatāne in the Bay of Plenty erupted, resulting in the deaths of 22 people and injury to 25 others, most of them critical. The bodies of two victims were not recovered.
7. Crater Lake, Oregon: Wild (2014) The movie “Wild”, starring Reese Witherspoon, chronicles one woman's journey as she tries to recover from a recent personal tragedy. Reese Witherspoon's character, Cheryl Strayed, decides to hike the 1,100-mile long Pacific Crest Trail alone.
For clean swimming lakes, consider Lake Superior (USA/Canada) for its vast, cold clarity, Lake Jocassee (USA) for waterfalls and lush surroundings, New Zealand's Blue Lake for world-record clarity, Australia's volcanic Lake Eacham/Barrine and silica-rich Lake McKenzie, or Europe's pristine options like Finland or Lake Bled (Slovenia), known for stunning alpine settings and pure waters. The cleanest lakes often feature volcanic origins, glacial melt, or silica sand beds that filter impurities, providing exceptional clarity and appeal.
In 1987 these images were taken at the bottom of Crater Lake by scientists in a deep diving rover vehicle.
When will Yellowstone erupt again? We do not know. Future volcanic eruptions could occur within or near Yellowstone National Park for the simple reason that the area has a long volcanic history and because there is hot and molten rock, or magma, beneath the caldera now.
When Humans Nearly Vanished: The Catastrophic Explosion of the Toba Volcano.
An active underwater volcano off the Oregon Coast that was predicted to erupt in 2025 is now expected to erupt mid-to-late 2026. The Axial Seamount volcano is located nearly a mile beneath the sea, approximately 300 miles off the Oregon Coast, just west of Astoria and along the Juan de Fuca Ridge in the Pacific Ocean.
Marie Byrd Land, a 620,000-square-mile collection of glaciers and rock formations, lies in the western portion of the southernmost continent. Because of its remoteness, no nation has ever claimed it.
On May 9, 1926, Commander Richard Byrd announced that he had been the first to fly over the North Pole in his Fokker trimotor airplane, the Josephine Ford. Byrd submitted his navigational records to the U.S. Navy and a committee of the National Geographic Society, who verified his claim.
