Lavas with low viscosity such as those erupted at Kilauea in Hawai’i Volcanoes National Park flow easily, with flow fronts that move up to 6 miles (10 km) per hour. Speeds in channels or lava tubes on steep slopes can be as fast as 19 miles (30 km) per hour.
18 kwi 2023 · Basaltic lava flows, particularly pāhoehoe flows, may have a variety of surface features including hornitos, levees, tumuli, pressure ridges, and squeeze-ups. Highly vesiculated region near the top of a basaltic lava flow in Craters of the Moon National Monument.
30 wrz 2021 · Lava is continuing to ooze out of the Kīlauea volcano on Hawaii's Big Island a day after it began erupting.
15 lip 2019 · Recent lava flows stretch out for miles in a rocky wasteland that more closely resembles the Moon than Earth. Huge waves send sea spray dozens of feet into the air along the wild, craggy...
23 paź 2023 · New age data for rhyolite lava flows erupted in Yellowstone caldera suggest that the eruptions occurred in tight clusters. These results change the way geologists think about lava flow events and volcanic hazards in Yellowstone National Park.
3 paź 2022 · Lava flows are outpourings of molten rock from a vent onto Earth's surface during an effusive volcanic eruption. Fluid basaltic lava flows may travel great distances from their vent. But more viscous (less fluid) types of lava are not able to travel as far, and form shorter and thicker lava flows.
