Mauna Loa is one of five volcanoes that together make up the Big Island of Hawaii, which is the southernmost island in the Hawaiian archipelago. It’s not the tallest (that title goes to Mauna Kea) but it’s the largest and makes up about half of the island’s land mass. It sits immediately north of Kilauea volcano, which is well-known for a 2018 erup...
The eruption began Sunday night at its summit after a series of large earthquakes. It then spread to vents that formed in a rift zone where the mountain is splitting apart and it’s easier for magma to emerge. These vents are on the mountain’s northeast side and lava emerging there could head toward Hilo, which is on the east side of the island. Ken...
Mauna Loa is not exploding like Washington state’s Mount St. Helens did in 1980, killing 57 people. That eruption sent ash soaring over 80,000 feet (24,384 meters) and raining down as far as 250 miles (400 kilometers) away. The magma in Mount St. Helens tends to be stickier and traps more gas, making it much more likely to explode when it rises. It...
Lava: Molten rock could cover houses, farms or neighborhoods, depending on where it flows. But lava from the northeast rift zone will likely take at least a week to reach populated areas, allowing...Volcanic gas: Mauna Loa is releasing volcanic gases, mostly sulfur dioxide. The gases are present in their highest concentrations in the immediate area around the summit crater or vents. But they a...Mauna Loa released about 15,000 tons of carbon dioxide per day during its 1984 eruption, according to USGS data. That’s equivalent to the annual emissions from 2,400 sport utility vehicles. Scientists say all of Earth’s volcanoes combined emit less than one percent of the carbon dioxide that humans produce each year.
Dec 1, 2022 · Mauna Loa - the world's largest active volcano - is erupting for the first time since 1984. Lava is flowing down the side of the volcano at a temperature of 1,000C, but experts say this does...
Dec 1, 2022 · 1 December 2022. Watch: Spectacular scenes as Hawaii volcano erupts. Mauna Loa - the world's largest active volcano - is erupting for the first time since 1984. Lava is flowing down the side of...
Dec 1, 2022 · Mauna Loa, Earth’s largest active volcano, abruptly woke up on November 27 after an almost 40-year nap. The volcano shot fountains of lava as high as 50 meters into the air, while rivers of...
Jun 8, 2023 · Kilauea, the second largest volcano in Hawaii, began erupting Wednesday morning, officials with the U.S. Geological Survey said in a statement. Kilauea, one of the world’s most active volcanoes, erupted from Sept. 2021 to Dec 2022. A 2018 Kilauea eruption destroyed more than 700 residences.
Jun 3, 2024 · Volcanic Activity Summary: Kīlauea volcano is erupting. A new eruption began at approximately 12:30 a.m. HST on Monday, June 3, likely about a mile (1-2 km) south of Kīlauea caldera and north of the Koa'e fault system and Hilina Pali Road, within Hawai'i Volcanoes National Park.
