Mauna Loa's last volcanic eruption in Hawaii lasted three weeks in 1984, but some volcanoes erupt for months or years.
to see the dangerously beautiful scene, many want to know when Mauna Loa will stop actively erupting.
Scientists use techniques including looking at a volcano's eruptive history, seismographic detections of earthquakes, and monitoring ground deformation and changes in gas emissions to predict when an eruption is impending. Earthquakes and tremors almost always happen before an eruption, according to the Smithsonian Global Volcanism Program.
According to the U.S. Geological Survey, "increasing rates of earthquake activity and ground deformation on Mauna Loa began in late September, providing clues to the accumulating magma below the surface."
