Hawaii Volcano Explainer FILE - Volcanic ash and steam rises from Mount St. Helens, Wash., as it erupted, May 18, 1980. The ground is shaking and swelling at Mauna Loa, the largest active volcano in the world, indicating that it could erupt. Hawaii volcanoes like Mauna Loa tend not to have explosive eruptions like Mount St. Helens in Washington state. That's because Hawaii's volcanoes have magma that's hotter, drier and more fluid, and doesn't trap as much gas, according to Hannah Dietterich, a research geophysicist at the U.S. Geological Survey's Alaska Volcano Observatory.

The ground is shaking and swelling at Mauna Loa, the largest active volcano in the world, indicating that it could erupt. Kilauea is well-known for a 2018 eruption that destroyed 700 homes and sent rivers of lava spreading across farms and into the ocean. (AP Photo/Caleb Jones, File) (Caleb Jones)

Hawaii officials are warning residents of the Big Island to prepare for the possibility that the world's largest active volcano may erupt given a recent spike in earthquakes at the summit of Mauna Loa. Scientists don't expect the volcano to erupt imminently, but officials are reminding people lava could reach some homes in just a few hours when it does. (AP Photo/John Swart, File) (John Swart)

Spain Volcano Lava flows from a volcano on the Canary island of La Palma, Spain, Saturday Oct. 2, 2021. An erupting volcano on a Spanish island off northwest Africa has blown open another fissure on its hillside. Authorities were watching Friday to see whether lava from the new fissure would join the main flow that has reached the sea. The new fissure is the third to crack open since the Cumbre Vieja crater erupted on La Palma island Sept. 19. (AP Photo/Daniel Roca) (Daniel Roca)
